Studies on Atomic Absorption Spectrophotometric Analysis of Chromium in Urine by Trioctylamine
Trioctylamine을 이용한 뇨중 크롬의 원자흡수 분광분석에 관한 연구
Abstract
As chromium in urine remains as oxychromic acid ions, chromium was extracted by using ion pair formed by anion exchanger trioctylamine. then after it is noted whether this TOA-MIBK method is effective or not for the chromium analysis by using flame method of Atomic absorption Spectrophotometric Analysis. The result is as following. 1. Effects of various acids on the extraction of Cr with MIBK including TOA are good in order
