摘要/Abstract

摘要： 前言近年来表面活性剂用于分光光度法测定微量金属离子浓度有很大发展,但发表的论文以阳离子型居多。鹤见近夫^[1]用阳离子活性剂测定微量锆,对测定条件做了系统研究,并对干扰离子的掩蔽进行了讨论。

Abstract: A method of Spectrophotometric determination of small amounts of zirconium with chrome azurol S (CAS) in the presence of non-ionic surfactants TritonX-100 was investigated. The color of zirconium complex is blue in a pH range from 5.7 to 6.6 at 605 nm and is stable for at least 120 minutes. Beer's law is obeyed up to concentration of 1.25 μ g/ml of zirconium. The molar extinction coefficient of the complex at 605 nm is 3×10⁴ mol^-1 cm^-1. The complex composition of zirconium to CAS was confirmed to be 2:3 by continuous variation method. A number of ions which interfere with the determination can be masked by the addition of various masking agents.
