Speciation of chromium in seawater by ICP-AES with dual mini-columns containing chelating resin.
A method for the preconcentration and speciation of chromium in seawater was developed. On-line preconcentration and determination were carried out by using inductively coupled plasma atomic emission spectrometry (ICP-AES) with dual mini-columns containing a chelating resin. In this system, Cr(III) was collected on the first column. The effluent containing residual chromium from the first colum...
متن کاملOn-line preconcentration system using mini-column packed with a chelating resin for the characterization of seasonal variations of trace elements in seawater by ICP-MS and ICP-AES.
An on-line column preconcentration technique coupled with inductively coupled plasma-mass spectrometry (ICP-MS) and -atomic emission spectrometry (ICP-AES) was developed using a mini-column (ca. 3 mm i.d., 40 mm length), that was packed with chelating resin (0.2 g) of iminodiacetic acid groups, Muromac A-1. After the preconcentration step, the column was washed with ammonium acetate buffer (pH ...
متن کاملChromium Speciation in Water by HPLC/ICP-MS
Chromium exists primarily in two forms: trivalent and hexavalent. Trivalent chromium is present in the cationic form as Cr+3 and is an essential nutrient, but hexavalent chromium is toxic and exists as an anion, either as chromate (CrO4 -2) or dichromate (Cr2O7 -2). Therefore, the analysis of total chromium does not always provide a true indication of the effects of chromium present in a sample...
