Spectrophotometric Determination of Chromium in Piperonal Fluorone Microemulsion Medium

ZHONG Ming hua, MO Chun sheng, LIN Chun hua (Institure of Chemistry and Biology Science,Jiangxi Normal University,Nanchang 330027,China)  
The colour reaction of chromium with piperonal fluorone in microemulsion has been studied.Its apparent molar absorptivity is 9.5×10 4 L·mol -1 ·cm -1 (measurement wavelength 595 nm,reference wavelength 525 nm).Beer′s law is obeyed in the range of 0~7/25 μg/mL for chromium.This method can be applied to the determination of chromium in steel with satisfactory results.
