阳极溶出伏安法测定塑料制品中的铜和铅
Anodic Stripping Voltammetric Determination of Cu and Pb in Plastics
【摘要】 <正> 铅等重金属的化合物常用作塑料的稳定剂。由于铅等重金属对人体有害,因此研究塑料制品中铅、铜含量对人体健康的影响是环境卫生学急待解决的问题。本文介绍的方法中,0.5M HCl既作为干法灰化塑料残渣的溶解液,同时又是测定铜、
【Abstract】 In this paper a solution of 0.5M HCl was used as both the solvent for plastic ash indry pcocess and supporting electrolyte for the determination of Cu and Pb.The best oringinalsolution of 0.5M HCl-5×10-5M Hg2+ was selected. The sultable concentration for Cu and pbdetermination wete<100ppb.The peak potentials for Cu and Pb are--0.22 and--0.45 respectively.The lowest limit for determinationis 1μg/l.
