Spectrophotometric Determination of Haxavalent Chromium in Bago River Water

In this research, hexavalent chromium in Bago River water was determined by spectrophotometric method. Collections of the samples were carried out during December 2019. Six sampling sites were chosen and the samples were collected in a clean plastic bottle. The distance between the first sample collection site and the last site is about 4.7 km. For chromium determination, spectrophotometric method based on the formation of coloured complex between Cr (VI) and 1,5-diphenylcarbazide were used. Firstly, the wavelength of maximum absorption (max) of the colour complex was determined and the max value was found as 540 nm.
