title: Applying magnesium hydroxide coprecipitation method for trace analysis to dialysis concentrate.
abstract: A magnesium hydroxide coprecipitation technique for determination of Cd, Co, Cu, Mn, Ni in dialysis concentrate is described. The analytes are concentrated from 10 ml of dialysis concentrate into 1 ml of 1 M HNO(3) and subsequently determined by graphite furnace atomic absorption spectrometry. Coprecipitation parameters and matrix effects are discussed. The precision, based on replicate analysis, is around 5% for the analytes, and recovery is quantitative, based on analysis of spiked samples and solutions including matrix components.
