| Abstract: | A method for determination of Au,Ag,Pt and Pd in Co -r ich Mn-crust samples by ICP-AES was studied. A combined preconcentration metho d using anion-exchange resin and activated carbon was used. The detection limit s (ng/g) of Au, Ag, Pd, and Pt are 1.3, 0.4, 0.6 and 4.8,respectively. The recov eries with standard addition for Au,Ag,Pt and Pd range from 89.0%~110.3% with precision of 3.5%~7.8% RSD(n=4). The method shows advantages of high accura cy, simple and convenient operation. The method has been applied to the determi nation of Au,Ag,Pt and Pd in Co-rich Mn-crust samples with satisfactory resu lts. |
