Quantittative determination of cr (vi) by diphenylcarbazide reagent

Abstract: 

A quantitative method of Cr (VI) - determination by using diphenylcarbazid reagent was studied in detail. This method exhibits a very high sensitivity in analyzing Cr(VI) in water samples. The optimal condition for the determination of Cr (VI) was established. If in the samples, the much excess of Cr (VI) compared with DPC the maximum absorbance of color complex would be reduced. This is very important problem when use of the method in practice.
