磷化铁湿法消解方法的探究

Discussion on Wet Test Method of Iron Phosphide

探究了不同湿法消解磷化铁后试液的准确性。湿法消解磷化铁实验过程中,利用硝酸溶解,溶解不够完全;王水或混酸进行磷化铁消解,溶液较为完全,测试数据准确稳定。其中,王水消解方法测定准确,经济实惠,危险性小,消解耗时短。最终选择王水进行磷化铁试样的消解。

In the experiment of wet digestion of iron phosphide,the dissolution of nitric acid is not complete,and the digestion test of aqua regia and tetracarboxylic acid is complete,and the test data is accurate and stable.Compared with four acid digestion,aqua regia test is more economical,less dangerous and takes less time to digest.Using aqua regia to digest iron phosphide and test the contents of iron and phosphorus,the accuracy is high,the risk is low,the recovery rate is high and the stability is good.
