摘要

An analytical scenarion was developed for determining micro- (trace i elements in water with ultralow mineralization using inductively coupled plasma mass spectrometry in combination with the method of single- and multielement standard additions. The conditions of instrumental analysis were described. Groups of trace elements that can be determined by the method of single- and multielement additions (concentrations 0.05-100 #mu#g/kg) calculated on the basis of element distribution in the studied water were recommended; the additions were introduced by gravimetry. Internal standards for the test element isotopes used to calculate concentrations were selected, and correlation equations were derived. Performance characteristics of the results of analyses were estimated.
