摘要
探讨了砷矿石、锑矿石等有色金属矿石中银的测定方法。矿样用盐酸－硝酸－氢氟酸消解，氢溴酸－高氯酸去除基体干扰，原子吸收分光光度法测定，结果满意。
Through the atomic absorption spectroscopy(AAS) is usually used to measure Ag in nonferrous ores, the digested method is very important for the upgrade of measuring precision. In order to accurately measure micro or macroAg, the samples were digested by HClHNO3HF and removed matrix interference from As and Sb by HBrHClO4. Then, they were put into flame or graphite furnace to directly analyze. With advanced equipment, a perfect result are obtained using the rteatment process.
