AAS

Tried to run AAS today..trying to learn A-Z step, starting from switching on the plug, gases, flame, check on sensitivity, troubleshooting and running few standards...

various lamps (depends on ur metal of interest)

plug

the acetylene

air compressor

AAS, use only acetylene and Nitrous oxide gases but it depends on the metal of interest..could detect only 1 metal at a time. need to have its own metal lamp before can proceed with experiment. If we want to run Nickel and Manganese, have to make sure we have those lamps..Need to prepare ultra pure water (UPW) and nitric acid for washing (3-5%).

It doesnt require long time for warming up, only about half an hour..likewise ICP, it requires at least 3 hours and more complicated during start up. I found out that using AAS, could make my life easier..heheh but the problem is, it could not detect metals at more than 5ppm.Cancel using AAS, so we end up just trying to familiarize with it..

Nickel 20ppm R1

Not that healthy anymore..

I have gastric since I was in Diploma..Terrible one starts when I was in Semester 4 if Im not mistaken..I didnt go to class, and always have to go to clinic to take medicines..

When I was in Degree, I didnt have much problem with my stomach...maybe coz im leading a happy life..? hehehe no stress at all..enjoying work, classes, assignments, good relationship with family, friends and lecturers...but still I have to take medications if things get worst...sometimes, especially fasting month..Ill get my medicine HISTAC, from Pusat Kesihatan...2 tablet a day, 1 for sahur and one for buka puasa..thats how my life works with medicine...

But now, its getting worst..previously I only have the feeling of unease at the lower abdomen, u can feel like 10 people is trying to pull ur nerves in stomach...I can feel the pain, its so painful..

Now, its the feeling of acids u know like, moving upward from ur stomach to the esophagus and to your mouth..its so painful..sometimes, ull feel like u cant eat anything, when u even drink, feels like choking, when u eat, u can feel that its so pedih la..

So i went to the clinic this morning to get some medicines, they gave me..

1. Pariet 20mg rabeprazole sodium (controlled medicine)
2. Maalox Plus Tab gelusil tab
3. Buscopan 10mg

need to finish it allllll!!!! huhu oh, by the way, the DR. asked me...

makan lambat? stress? bnyk keja? hahaah its all TRUE!

Mock viva..

Mock viva was held at our lab, old civil building..

Viva for 2 colleagues, its for the preparation of the viva for masters..

Lot of things been stressed out by Prof, will update later..no time to type now...will get back to u all!

Questions been asked by Prof:

1. How do u know that this method is cheaper?
2. Have u make any comparison?
3. relevance of objective to your work?
4. of all heavy metals, y only nickel?
5. there are a lot of contaminated area, y x study other metals?
6. which is more advantages? production of methane or sulphide?
7. y nagaoka?
8. how u know mpb or srb?
9. if u get it from someone else, how can u verify whether it is correct?
10. how much surpluss of H2S in your experiment?
11. where did it go if sulphide does not fully react with heavy metals?
12. look at the mass balance n explain
13. y decide 3ppm Cu?
14. y choose pearson?
15. possible pathway for sulphide oxidation?
16. how did u know that the assumption is correct?
17. what are the probles associated with sulphide?

at least i got the overview on the questions been asked by panels n i can prepare some answers..hope my viva time, i can answer all question ask by panel confidently although it seems impossible..! ill try my best from now on to understand what im doing, look back at all the basic things and try to generate on question just to trigger me..! he..:-)

House-MESSY??

Emmmm...im all by myself? hahaha...so meaning that im alone in my house for quite some time...sure when mom come back and she is gonna be truly shock...hahaha

Coz i usually dont have time to do some cleaning..

Too focus and too dedicated to my work..haha

so to avoid that, I do some cleaning today...coz i want to clean up the toilet, so i clean up the hall n kitchen too..throwing unwanted things, sweep, mop the floor, washing my clothes n some many things n im sweating..which is GOOD...makes me feel healthier and not always feeling sleepy..hehe

will continue on cleaning up house tomorrow, now its bathing time and after that I can go to the dumpster downstairs to dump everything!!

National Postgraduate Seminar 2011

Event was held at Lecture Hall B, Level 6 Faculty of Civil Engineering from 14th-15th June..

I presented my paper yesterday, the 1st presenter at 10.30am..

Guess who's my panel???

• Dr Aminuddin
• Prof Dr Ruslan Hassan

Dr Amin was evaluating me for the very 1st time, for Prof Ruslan, its his 2nd time..

Ive presented the same paper as the ICCE one..So most likely the same except I need to elaborate more as the time for this presentation is 20 minutes compared to ICCE, only 10 minutes... I think the presentation was okay...give a big clap to me!!! yaaaa!

few questions been asked:

1. What are the mechanisms/interaction between both metals and sulphide?
2. need to also consider time/duration in order to make it better
3. how does it mix..?
4. only 1 metals?
5. what are other metals?
6. y need to have sterilized?, doesnt look necessary..

Preparation of dilution water for BOD

Pipetting chemicals

Adding chemicals

Adding distilled water till the mark

Leave it for 1 hour

Preparing the dilution water for BOD...

4 chemicals added with each 1ml per 1L of water..

so if yours requires 4L of water, just add 4mL for each chemicals...

Calculated by, each BOD bottle requires 300mL so times with your samples...

simple! if u have 8 samples like mine, 300mL times by 8..so around 2.4L rite? I prepare 3L of dilution water then...

Sampling and BOD

Samples taken, approx 30L..heavy

Labelling and separating the samples for each testing; BOD, COD, SS.

Purging nitrogen gases for 30minutes for both reactors

Prepared samples for BOD

For BOD5

Testing with DO meter

huhu...start my day with sampling at Indah water treatment plant at Section 7, Shah Alam.

Sampling starts at 8.30am, waiting for the worker to assist me..

Then, after sampling..have to send Nik to old lab for autoclave...Filled up my reactor with wastewater and take few sets of samples for other testing as well..

Done with that, proceed with BOD, for both reactors and wastewater characterization..

My day is filled with lab work and Im happy today coz nothing happen that would interfere my work..

Happy+Tired, heheh...

Sad..huhuh I cried!

GERMS!!!!

BAD GERMS!!! HUH!

• Hate the fact that u cannot even do a thing when u r sick!
• Hmm....thats what happen to me for the past, hmmm let me count. I feel so sick on friday, almost 5 days!!!! What???? and Im here, sitting at home, cant think or do anything!!! damn...
• I just wish Ill get my life back, get good health so that I can proceed with my work..Am i right?
• I have this running nose, headache, backpain..everything lah..like all the germs are all over you, attacking u n i can feel it..Can I? or just my imagination? but its true...huhuhu
• sometimes feel hot and sometimes cold..
• Even Ive take medicine, it just wouldnt work..

Early June with a no mood situation

Oh my, Its June already..Not much lab work that Ive done..Im way back already..so many things happen..urgh, mad, mad all day long...

Sampled wastewater from Indah water treatment plant at Sek 7..., went back to the lab, having difficulties that all technician are mc, went for courses, off for holiday...

I have to re-do sampling coz i cant do my BOD test, which definitely make me damn mad, i transported 30L of samples and now it is all a waste..waste of time and energy.!!!!!

To whom should i complaint? if u guys r on leave, just let other people hold ur lab keys lah..easier what...now no spare keys, nobody knows bout it and Im mad again, reason which i cant really accept!!!!

Ive to cancelled everything, all that Ive planned, cancelled!!! huhuhu
