摘    要:本文研究了水中痕量铍的稳定性大小,与水中酸度、与水中存在的沉淀物种类及量以及与贮存容器有关,为了使标准溶液与水样中痕量铍不致因容器表壁吸附或沉淀物吸附而损失,经试验采用聚乙烯瓶盛装最好,并用盐酸或硝酸调至溶液酸度为pH1-2为好。

关 键 词:  测定  稳定性

Abstract:In this article the action and the stability of trace Beryllium in water is studied, which arc related to not only the acidity, but also the kinds and quantities of precipitates in water and the container. In order to provcnt the standardized solution and the trace of Bcrillium in water sample from lose for the adsorption on the surface of the container and the absorption of the precipitates, we had belter use the polyvinyl flask as the container and adjust solution acidity to the pHl-2 range with the hydrochloric acid or the nitrate.
Keywords:stalilily  traces or Be
