Known test methods were used for detn. of Ag, Au, Pd, Pt in the title waste materials. Model solns. of the precious metals and waste matrix elements (Al, Cu, Fe, Zn) were used for confirmation of the method efficiency. The analytes were sepd. from the matrix model solns. by copptn. on Ni and Te substrates and ion exchange with strongly basic anion exchange resins. The pptn. with dimethylglyoxime was effective for sepn. of Pd only. The inductively coupled plasma optical emission spectroscopy was used as anal. tool.
