摘要
比色法连续测定磷酸中铁、铝的含量 ,是在一定酸度条件下 ,试液中的Fe3+ 和Al3+ 与试铁灵 (又名7 碘 8 羟基喹啉 5 磺酸 )反应 ,生成金属 有机配位体络合物。分别在 3 65nm和 5 90nm波长下进行比色 ,求得磷酸中铁、铝的含量。本法精密度和准确度较好 ,具有简便、快速、连续测定的优点。
Samples were reacted with 7 iodo 8 hydroxylquinoline 5 sulfonic acid in the medium of acid to form metal orgnic liand compounds,which were measured with colorimetry in 365 nm and 590 nm respectirely to determin ferric and aluminium.The methoal was precise,accurate,simple,rapid and could be determined successively.
