在伏安分析仪上,锆(Ⅳ)在0.15M盐酸-5.0×10~(-6)M水杨基萤光酮(SAF)-5.0×10~(-7)M溴化十六烷基三甲基铵(CTMAB)体系中有一灵敏的络合吸附波。锆(Ⅳ)浓度在2.0×10~(-8)M～2.4×10~(-7)M范围内,与导数波高成线性关系。水杨基萤光酮及锆(Ⅳ)与水杨基萤光酮络合物都在悬汞电极上被吸附,络合剂的还原峰电位为—0.74V,络合物的还原峰电位为—0.94V。当加入一定量的表面活性剂溴化十六烷基三甲基铵后,峰形变好,峰宽变窄,并且灵敏度有所提高。
On a voltammetric analyzer, zirconium (IV) is dissolved in 0.15 M hydrochloric acid - 5.0 x 10 ~ (-6) M salicylfluorone (SAF) - 5.0 x 10 ~ (-7) M cetyltrimethylammonium bromide Ammonium (CTMAB) system has a sensitive complex adsorption wave. The concentration of zirconium (Ⅳ) is in the range of 2.0 × 10 -8 M to 2.4 × 10 -7 M, which is linear with the derivative wave height. The salicylfluorone and zirconium (Ⅳ) and salicylfluorone complexes were adsorbed on the hanging mercury electrode. The complexing agent had a reduction peak potential of -0.74V and a complex reduction peak potential of -0.94V. When a certain amount of surfactant Cetyltrimethylammonium Bromide is added, the peak shape becomes better, the peak width narrows, and the sensitivity is improved.
