【摘要】 <正> 化学修饰电极近年来的研制十分活跃,它已渗透到各种不同的学科领域。现在已制成多种修饰电极,用于分析化学中,例如几种测定银离子的电极。本实验室在完成聚丙烯脒硫氰酸盐和聚丙烯酰胺肟两个修饰电极的基础上,又成功地将二硫代氨基甲酸盐树脂(DCBR)修饰到石墨电极上,用于银离子的分析,现将试验及结果介绍如下。更多还原

【Abstract】 Dithiocarbamate resin chemiclly modified graphite electrode has been fabricated and applied to the analysis of siliver ion in the aqueous media. Its detection limit of Ag+ is 1.0× 10~5M. Experimental results indicated that coexisting ions, such as Na+, K+, Ca2+ , Mg2+ , Fe2+, Zn2+, Bi3+ , Cu2+, Pb2+, Pt2+ , Au3+ , Ir3+, Ru4+ , Pd2+ do not interfere with the determination of siliver ion.更多还原
