Sample preparation for chromium speciation

Speciation of Cr(III) and Cr(VI) in environmental samples by solid phase extraction on Ambersorb 563 resin

“…Chromium is a major water pollutant, usually as a result of some industrial pollution including tanning factories, steel works, dyeing or chromium plating, wood preservation, etc. and artificial fertilizers [3,4]. For this reason, determination of chromium in environmental samples as natural water, waste water samples and soil samples has become very important.…”

Speciation of Cr(III) and Cr(VI) in Environmental Water Determined by Selective Separation and Preconcentration on the PBST-RSP

“…In water, chromium can usually be found in two different oxidation states including hydrated Cr(III) and Cr(VI) species with different physiological effects [2]. Cr(III) is a trace element essential for maintaining glucose, cholesterol, and fatty acid metabolisms in biological cells [3][4][5]. But Cr(VI) with a high oxidation potential and relatively small size can easily permeate through biological cell membranes, and is known as a carcinogenic and mutagenic substance for humans [3].…”
