Determination of Trace of Elements in Lead Crystal Glass by Axial View ICP-AES

The sample of lead crystal glass was dissolved with HF and HClO4,and contents of 15 trace elements,including Al,As,Ba,Ca,Er,Fe,Mg,Nd,Ni,Sb,Sn,Sr,Ti,Zn and Zr in the sample solution,were determined by axial view ICP-AES.The output voltage and flow rate of spraying gas of the ICP-AES instrument were studied and optimized.Values of detection limit (3s) of the method found were less than 0.03 mg·L-1.The proposed method was applied to the analysis of sample of lead crystal glass,giving values of RSD′s (n=6) for the 15 elements in the range of 0.01%-2.10%.
