电感耦合等离子体原子发射光谱法测定焊剂中的磷元素

ICP-AES method determination flux of P element

建立了焊剂中磷元素的电感耦合等离子体原子发射光谱（ICP-AES）的测定方法,样品经盐酸、硝酸溶解,于优化选定的仪器条件下测定磷元素.使用本方法与熔炼焊剂化学分析方法-钼蓝光度法测定磷量（JB/T7948.8-1999）结果一致.测定回收率均在96.0％～98.0％之间,标准偏差小于0.8％,该法操作简便,分析快速,结果准确,比钼蓝光度法更为快速。

To establish the determination method of flux in P using ICP-AES. Samples dissolved hydrochloric HC1-HNO3 dissolve. To optimize the selected instrument under the condition of P element. Using this method and the heat flux of chemical analysis molybdenum blue photometric method for determination of P amount （JB/T7948. 8-1999） consistent results. In the determination of recovery 96.0%～98.0%. The standard deflation is less than 0. 8%.The method is simple, rapid analysis theresults are accurate.More quickly than molybdenum blue photometeie method.
