| Abstract: | Applied 200 g/L ammonium sulphate solution 10 mL and 5 mL ammonia water as dissolvent,EDTA titration method was used to determine zinc oxide,and after 5min,the sample was dissolved completely.The impurities of zinc and iron oxide did not interferes with the determination of zinc oxide.The result was identical with the traditional method,and the RSD was less than 0.11%. |
