Determination of Arsenic,Copper,Manganese,Molybdenum,Phosphorus and Silicon in Ferrotungsten

Determination of arsenic,copper,manganese,molybdenum,phosphorus and silicon in ferrotungsten by inductively coupled plasma atomic emission spectrometry.

A simultaneous determination method of arsenic,copper,manganese,molybdenum,phosphorus and silicon in ferrotungsten by inductively coupled plasma-atomic emission spectrometry was established.The samples were dissolved with oxalic acid and hydrogen peroxide.The matrix elements(W and Fe) and other coexisting elements had no interference with the testing elements.Under the optimal conditions,the detection limits of arsenic,copper,manganese,molybdenum,phosphorus and silicon were 0.009,0.006,0.000 1,0.000 3,0.005 and 0.002 μg/mL,respectively.The standard addition recoveries were 95 %-108 %,and the relative standard deviation(RSD,n=3) was 0.1 %-3.3 %.The proposed method has been applied to the determination of certified reference material,the results were in good agreement with the certified values.
