Advanced techniques for bioinorganic and environmental speciation analysis for heavy metals.
Résumé
A review with 33 refs. concerning advanced techniques for bio-inorg. and environmental speciation anal. for heavy metals is given. Topics discussed include: metals and species of interest ( Sb, Cd, Cu, Zn, Cr, Pb, Hg); instrumental aspects (purge-and-trap thermal desorption, gas chromatog.-based, liq. chromatog.-based, and electrophoretic techniques); sample pretreatment for speciation anal. (sepn. from sample matrix, derivatization, pre-concn.); and speciation of individual elements (Cr, Pb, Hg, Sn, porphyrin-bound elements, metalloprotein-bound elements). [on SciFinder(R)]
