【Abstract】 The optimum conditions for determining trace of cobalt and nickel in high purity lead by FAAS were studied. Parrent lead was separated by hydrochloric acid precipitation. The filter liquor was evaporated to volatilise excessive hydrochloric acid and concentrate cobalt and nickel. FAAS′s measurement limits of cobalt and nickel are above 0 3 μg/g and 0 12 μg/g, respectively. Satisfactory results were obtained by using the method in determination of trace of cobalt and nickel in refined lead product and semi product of a lead smeltery.更多还原
