Studies on Atomic Absorption Spectrophotometric Analysis of Chromium in Urine by Trioctylamine
|
|
|
|
|
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.
@ES The results is as following:
@EN 1. Effects of various acids on the extraction of Cr with MIBK including TOA are good in order HNO3, H2SO4, HCI in distilled water sample and its proper concentration of HCI is 0.2N.
