Abstract
An overview is given of current analytical methodologies for arsenic s peciation in environmental samples. Most of these are conventional ins trumental methods - mainly chromatographic techniques (HPLC, GC, etc.) coupled with a variety of detectors. However, methods using micro-org anisms are increasingly being applied for the removal of metal ions an d other metal species from aqueous solutions. The use of the alga Chlo rella vulgaris is proposed for the separation of arsenic(lll) from the other arsenic species. The arsenic concentration is measured by hydri de generation atomic absorption spectrometry. (C) 1998 Elsevier Scienc e B.V.
