摘　　要：将凝胶层析与荧光分光光度法相结合进行饮用水中铝形态的分析.结果表明,凝胶层析对胶体态铝和溶解态铝有较好的分离效果.依据衍生试剂8-羟基喹啉(8-HQ)和铬蓝黑R(EBBR)与不同铝形态结合强度的差异,通过荧光分光光度法可分析饮用水中的单核铝、无机单核铝,再结合硝酸消解可测定饮用水中的总铝、溶胶态铝和胶体态铝.对饮用水中铝形态的分析表明:清华大学地区的地下水和北京市给水管网末端水的总铝含量均在50μg·l-1以下,无机单核铝为饮用水中铝的主要存在形态.In this paper, gel-separation chromatogram and fluoremetry were applied to analyse different forms of aluminum in drinking water. The resuhs show that gel separation chromatogram has a good separation effect on colloidal Al and soluable Al. According to the binding ability difference between 8-hydroxylquinoline/EBBR and different Al forms, monomeric Al, inorganic monomeric Al, colloidal Al, soluable Al and total Al in drinking water were analysed. Experiment results show that the total Al in Tsinghua university underground water and Beijing municipal drinking, water are both below 50μg·l^-1 and that monomeric AI is the main aluminum form.
