Název v původním jazyce

Simultaneous Determination of Inorganic Arsenic, Antimony, Selenium and Tellurium by ICP-MS in Environmental Waters Using SPE Preconcentration on Modified Silica.

Popis výsledku v původním jazyce

This paper deals with a simplified multielement profiling of inorganic arsenic, antimony, selenium and tellurium in the form of 75As, 82Se, 121Sb and 125Te by ICP-MS for amounts less than 10 ug/L. Internal standards such as 72Ge and 209Bi were successfully used for the suppression of both influence of macro elements Na+, K+, Ca2+, Mg2+ or Al3+, and interference of limited concentrations of heavy metal ions. Modified silica sorbents Separon SGX C18, C8, CN, NH2, RPS and Phenyl were tested for the preconcentration of As, Sb, Se and Te (0.25-5 ug/L) in the form of ion associates with cationic surfactants from 50-250 mL sample volume. 1-etoxycarbonyl-pentadecyltrimethylammonium bromide (Septonex 0.005 mol/L) was suitable for this purpose in the presence of4-(2-pyridylazo) resorcinol, 2-pyrrolidinecarbodithioate and 8-hydroxyquinoline-5-sulphonic acid. The quantitative retention occurred at pH 7 and the mixture of acetone with ethanol in ratio 1:1 in the presence of 0,1 mol/L HCl was used
