@@@@The sample is dissolved by hydrochloric acid and nitric acid,perchloric-acid to deduct carbon and oxide impurity elements,hydrofluoric acid to deduct the influence of silicon, then trisodium citrate as the complexing agent. Under alkaline conditions(Ph8~9),With dimethylglyoxime complexing nickel element to form a stable precipitate. The precipitate was weighed after drying at 120℃,then calculate the nickel content.The method has the characteristics of being easy to operate, fast, accurate, low-cost, @@@@and more suitable for the efficient analysis of large numbers of samples.
