| Abstract: | A method for the determination of cobalt and nickel by FAAS analysis was presented.Four acids were adopted to dissolve samples by controlling the acidity around 4%.The determinations were monitored with state-level standard samples.The method proved to be rapid and simple.It can be applied to measure sulfide phase positive ultra-basic rocks,iron oxides phases and mild acidic rock phases.For the various rock samples,the leaching rate of cobalt is 90%～100%,nickel is 96%～100%.The detection limit is ω(Co,Ni)/10_6=0.001-0.005. |
