摘要
本文采用王水、硫磷混酸溶解试样，研究了应用ＩＣＰ－ＡＥＳ技术测定耐磨合金钢中Ｎｉ、Ｃｒ、Ｍｏ、Ｖ、Ｗ、Ｚｎ、Ｃｏ、Ｌａ、Ｃｅ、Ｔｉ、Ｍｎ、Ｃｕ１２种元素的方法。试验了硫酸、磷酸用量对测定的影响和共存离子干扰，方法相对标准偏差为１．４０％—３．２２％，回收率为９６．０％—１０８．１％。对试样进行分析，结果满意。
A method for determination Ni,Cr,Mo,V,W,Zn,Co,La,Ce,Ti,Mn and Cu 12 element of wear resisting alloy steel by ICP AES were studied.The sample has been dissloved in aqua regia,sulphur & phosphorus mixed acid.It was effective ,Ni,Cr,Mo,V,W and other metal element of alloy steel were decomposed, tungstic acid didn′t separate out.Influence of the volume of sulphuric acid and phosphoric acid were tested.Coexitence ion each other didn′t interfere detection.The relative standard deviation are 1.40%-3.22%,stardard recoveries are 96.0%-108.1%.The method has been applied to analyse practical sample,the satisfactory results were obtained.
