Оптимизация условий осаждения железа, никеля, титана, хрома, молибдена, кобальта, тантала, вольфрама и алюминия при ИСП-АЭС определении содержания галлия и германия

Abstract

For the first time a new approach for solving the problem of separation of trace analytes (Ga, Ge) from matrix elements (Fe, Ni, Ti, Cr, Mo, Co, Ta, Al and W) was suggested. Matrix elements provide an interfering effect on the results of gallium and germanium determination employing the ICP-AES analysis. It was found that required deposition conditions of macroamounts (Fe, Ni, Ti, Cr, Mo, Co, Ta, Al and W) should meet 0.082 mole K2C2O4 and 0.34 mole HF.
