Distribution of Chromium Species and Physico-Chemical Analysis of Various Industrial Effluents in Hyderabad and Jamshoro, Pakistan

This research aimed to quantify the speciation of chromium in different industrial effluent samples Hyderabad and Jamshoro, Pakistan. The hexavalent (Cr(VI)) was determined by microsample injection system flame atomic absorption spectroscopy (MIS-FAAS). total measured MIS-FAAS after oxidation trivalent (Cr(III)) Ce(SO4)2 an acidic medium (0.07 M H2SO4). content Cr(III) difference method (total – chromium). In textile fabrics industries, Cr observed 400 1600 times higher than US-EPA WHO regulatory limit (0.10 mg/L) discharge. food plastic Cr(VI) found be high as compared Cr(III), chemical well industries. (0.05 all selected but within (170 discharges.
