| Abstract: | A simple and rapid m}athod for the determination of Cd at low levels down. to 0.01ug Cd/l in seawater by anodic stripping voltammetry with a precision RSD of 6% and recovery of 92.5% is described. The method was based mainly on the principle of the positive "coordinating effect" of metallic ions during plating.In analysis, a sensitive AD-1 model polerography of Chinese manufacture and its mercury-film electrode was used without any preliminary treatment of the sample. The deoxygenation process was simply performed by adding 3 drops of saturated Na2SO3 solution to 50m1 of seawater sample without passing N2-gas.The total time for a plating and stripping cyae was 6 min. |
