The development of a technique in analytical chemistry for the determination of trace toxic elements in water by neutron activation analysis

Abstract

Techniques in preconcentration of some trace toxic elements from water samples based on co-precipitation with Fe(OH)₃ and/or adsorption on activates charcoal have been develop for the analysis of As, Sb, Mo, W, Co, Cr(VI), Cd, Zn, Hg and Se by neutron activation. After the reliability of developed techniques was checked, they were applied to investigate some trace elements in various kinds of water samples. The limit of detection was found in the range of 0.01-0.1 μg./l. For the concerning elements.
