摘　　要：设计了不同酸度、不同温度、接触空气等条件的贮存方案 ,对含铬形态化合物水样的贮存和铬形态稳定性进行了研究。认为 ,酸化水样不利于铬形态的稳定 ,低温、密闭对铬形态水样的保存有利。A series of reserving water sample containing chromium species scheme,different water sample,different acidity,different temperature,different contacting with air,were studied.The results are that acidified water sample is disadvantageous to the stability of chromium,sealing up and low temperature is advantageous to reserve the water sample of chromium species.The results of the reserving method and the stability of chromium species are of great useful for inspecting water quality.

关 键 词：铬 形态 贮存 稳定性
