Im currently preparing metal solution to be spike into the wastewater sample. As u can see the blue bottle is called 'Scott bottle' contains heavy metal (nickel. So the solution is actually wastewater from Mawar College in Uitm Shah Alam..
After preparing the solution, i need to spike each septum bottle with 4ml of nickel..
Need to inject the nickel solution with syringe, so have to be very careful...
