Speciation of chromium through aqueous two-phase extraction of complexes of Cr(III) with 4-(2-pyridylazo)resorcinol and Cr(VI) with 1,5-diphenylcarbazide

Speciation of chromium through aqueous two-phase extraction of complexes of Cr(III) with 4-(2-pyridylazo)resorcinol and Cr(VI) with 1,5-diphenylcarbazide

A green, sensitive and selective methods are described for the preconcentration and speciation of chromium species in natural waters. The developed methods are based on the environmentally friendly aqueous two-phase extraction with a system consisted of ammonium sulfate and polyethylene...
