Abstract:Pd-Ag-Cu-Au-Pt-Zn alloy is an important material widely used in spacecraft control system . It is great significance that establish an accurate and efficient detection method about its contents for improvement material performance and lower the cost.The alloy was dissolved by HNO3-HCl(1+3) with sealed-digestion at 140℃±10℃ and dilute solution, determination of copper, gold, platinum, zinc content in Pd-Ag-Cu-Au-Pt-Zn alloy by inductively coupled plasma optical emission spectrometry (ICP-OES). at optimal instrument operating conditions that power are 1300W; flow of nebulization gas 0.9 L/min; flow of auxiliary gas are 0.7 L/min; flow of plasma gas are 15 L/min;pump rate 1.5 L/min; observation in axial direction. It is selection wavelength Au 208.209nm、Cu 327.393nm、Pt 299.797nm、Zn 206.200 nm to result computation. The result show that content determination of copper, gold, platinum and zinc is free from interference.and results of precision and adding standard recovery 98.11%~100.30%, the results of precision 0.15%~0.26%. Compared with the complicated traditional national standard method, the measurement results are in good agreement. It is an accurate and simple method with good applicability.
