Extraction and spectrophotometric determination of zirconium(IV)
Description
A sensitive and selective method for the extraction and spectrophotometric determination of Zr(IV) with N-p-chlorophenyl-3,4,5-trimethoxycinnamohydroxamic acid (PTCHA) has been developed. The binary complex of Zr(IV)-PTCHA is extracted from 2-6 M HCl into chloroform, having a maximum absorbance at 385 nm; molar absorptivity 2.1 x 104 1 mol-1 cm-1. A ternary complex with xylenol orange (Zr-PTCHA-XO) have been studied in chloroform-ethanol media, which absorbs at 540 nm; molar absorptivity 4.3 x 104 1 mol-1 cm -1. The present method is applied for the analysis of zirconium in standard samples. 15 references, 3 tables
