Determination of mercury in mineral samples by employing a high temperature volatilization technique and activation analysis

Abstract

A high temperature volatilization technique was applied to lower the detection limit for the determination of mercury in mineral samples by neutron activation analysis to the 10-15 pg range. Activated charcoal was used to trap evaporated mercury. Geologic standard samples and weathering crusts from limestone buildings were analyzed. The data obtained indicate how the concentration of air pollutants varies. © 1991 Akadémiai Kiadó.
