Abstract

The results of ICP spectrometer measurements of low concentrations of lead and copper in aqueous solutions with preliminary concentration of a sample by means of a flow-injection system are presented. A significant decrease in the detection limits of the indicated elements has been obtained. The influence of different methods used for mathematical processing of the results of measurements on the error in determining elements in aqueous solutions has been investigated.
