摘　　要：采用1,10-邻菲啉分光光度法测定芦荟中痕量铁,在pH为2～9的溶液中试剂与铁生成红色的络合物.本方法可有效的消除共存离子的干扰,准确度和灵敏度高.分析结果表明,芦荟中铁的含量为8～10μg,回收率为96.7%～100.0%.The micro amounts of iron in aloe has been determinaed by spectropholometry system of 1.10-phenanthrolme.In pH 2～9 buffer solulion,A Kind of red complex were prepared by1.10-phenanthrolme and Fe(Ⅱ).This method could avoid interference of some coexistind ions,The accuyracy and sensitivity were inproved. The results in aloe is 8～10 μg/g ,The recoveries of the method are 96.7%～100.0%.
