Abstract

Abstract: A method of spectrophotometric determination of trace Cr（Ⅵ）with salicyl-fluoroketone in CTMAB micelle was described. The coexist interferential ions such as Fe³⁺, Cr³⁺ and Co²⁺ etc. were masked by diethylenetriminepentaacetic acid (DTPA), then Cr（Ⅵ）was successfully determined. The standard deviation of 0.246(n=10)，relative standard deviation of 2.56%，and recovery ratio of 93.00%-110.0% were obtained. This result is satisfactory for determination trace Cr（Ⅵ）in environment water samples.

Key words: spectrophotometry, salicylfluoroketone, cetyltrimethylammonium bromide, Cr（Ⅵ）, environment water samples
