摘要
本试验采用三价铁盐在碱性条件下生成氢氧化铁吸附磷，并使之与其他成份分离.对氢氧化铁沉淀加盐酸溶解后，用吸光度法测定，效果可靠。
This experiment changes trivalent ferrum into the absorbtion phosphorus of ferric hydroxide, under basicity condition and dissociates it from other components. It can he measured with absorbtion spectrophotometry after hydrochloric and dissolves ferric hydroxide. The result is reliable.
