有机试剂在吸附(溶出)伏安法中的应用,是60年代末提出的。由于有机离子所具有的特效性及待测离子的电化学特性,它们形成的络合物能在吸附(溶出)伏安法中提高待测离子的富集效率,使被测离子的选择性、灵敏度得到改善。随后,不少化学工作者对这工作进行深入研究、利用不同的有机试剂对钴和镍、锑、钼等离子进行探讨和测定。本文以三苯甲烷类染料——结晶紫大阳离子为沉淀剂、使与锑(V)氯铬阴离子缔合、在电极表面形成难溶化合物、而吸附富集,并进行阴极溶出。根据这一性质,测定了水样中的锑。在有机试剂吸附(溶出)
The use of organic reagents in the adsorption (dissolution) voltammetry was proposed in the late 1960s. Due to the special effects of the organic ions and the electrochemical properties of the ions to be measured, the complexes formed by them can enhance the efficiency of the ions to be detected in the adsorption (stripping) voltammetry so that the selectivity, Sensitivity improved. Subsequently, many chemical workers conducted an in-depth study of this work, the use of different organic reagents for cobalt and nickel, antimony, molybdenum plasma to explore and determine. In this paper, triphenylmethane dyes - crystal violet large cations as precipitating agent, with antimony (V) chloride chromium anion association, the formation of insoluble electrode surface compounds, and enrichment by adsorption, and cathodic dissolution. According to this property, the antimony in water samples was determined. In organic reagent adsorption (dissolution)
