FIA DETERMINATION OF COD IN ENVIRONMENTAL WATER BY STOP-FLOW TECHNIQUE;
流动注射停流法快速测定环境水样中COD
A flow injection analysis with stopped flow technique for the simultaneous deter- mination of aluminum and iron is developed based on the formation of Al (Ⅲ), Fe (Ⅲ)- chrome azurol S-cetylpyridinium bromide blue ternary complex in weak acidic solution and double standard addition.
在弱酸性溶液中,基于铝、铁与铬天青S、溴化十六烷基吡啶形成蓝色三元络合物,采用两次标准加入法,建立了流动注射停流技术同时测定铝、铁的新方法。
