【Abstract】 A technique combing the flow injection on line preconcentration and separation with the atomic absorption spectrometric detection was proposed and its usage in the deter- mination of trace gold for ores and rocks of geological samples was studied Experimental con- ditions and parameters were investigated in detail. The method is simple, rapid and precise and it’s detection limit is 0. 018×10^-6.更多还原
