采用氢氧化镁共沉淀法测定透析液中的镉、钴、铜、锰、镍。将10 ml透析浓缩液中的分析物浓缩至1 ml 1 M HNO3中，随后通过石墨炉原子吸收光谱法测定。讨论了共沉淀工艺参数和基体效应。基于重复分析，分析物的精密度约为5%，基于加标样品和溶液（包括基质组分）的分析，回收率为定量。
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 HNO3and 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.
