| Abstract: | With the purpose of rapid and accurate determination of Fe3+ and Al3+ in aluminum sulphate used as water purifying agent,the feasibility of re-titration with copper salt complexed with ethylene diamine tetraacetic acid(EDTA) was studied and the factors affecting the method were investigated.The results show that under the optimized conditions,the recovery rate of standard addition is in the range of 95.2%-103.5%,continuous determination of Fe3+ and Al3+ in aluminum sulphate can be achieved,and the method is characterized by rapidness,simplicity and accuracy. |
