利用表面活性剂胶束增溶分光光度法测定铝,已有大量报导,并已应用于金属、合金及矿石中铝的测定。然而资料中,钙的允许量一般在500～2500微克间,钙量更多对测定铝是否有影响,未见进一步的探讨。本文就纯钙中铝的直接光度测定,进行了必要的条件实验,在铝-铬天青S(CAS)二元体系的基础上,比较了氯化十六烷基吡啶(CPC)、溴化十六烷
The use of surfactant micellar solubilization spectrophotometry for the determination of aluminum has been reported extensively and has been used in the determination of aluminum in metals, alloys and ores. However, the data, the allowable amount of calcium is generally 500 to 2,500 micrograms, more calcium on the determination of whether the impact of aluminum, no further discussion. In this paper, the necessary conditions for the direct photometric determination of aluminum in pure calcium were investigated. Based on the binary system of aluminum-chromium azure S (CAS), the effects of cetylpyridinium chloride (CPC), brominated Hexadecane
