摘要
The sample is decomposed with sodium hydroxide and acidified,Fe and Ti,etc,are separated under the existence of EDTA.Al is coordinate with excessive EDTA in the weak acid solution.The excessive EDTA is titrated with Zn standard solution,then EDTA coordinate with Al is replaced with villiaumite.Finally,the replaced EDTA is titrated with the Zn standard solution.
