【Abstract】 A method has been presented for the determination of trace lead in polyethylene plastics. In 0.4 mol/ dm³ solution of hydyochloric acid containing 0.04% Triton X-100 the anodic stripping peak height of lead is increased. The detection limit is 1×10^-9g/ml. This is a rapid and sensitive method for the determination of lead in polyethylene plastics.更多还原
