| Abstract: | A simultaneous determination procedure for multielements of micro amounts of Na, K, Ca, Mg, Cu, Fe, Co, Ni, Mn, Zn and Cd in lithium carbonate by ICP-AFS has been presented. The standard addition method can be used to eliminate the matrix and interelement interferences. The detection limits of some elements to be determined can be improved with a concentric flow pneumatic nebulizer and further using methane as reductant. |
