| Abstract: | Gold in industry waste is determined by activated carbon concentrationa and atomic absorption spec trophotometry. First, sample must be selected. Secondary, organism in the sample is oxidized with mixed acid, and gold in it is dissolved with aquaregia. A part of test solution is taken in order to concentrate gold completly with activated carbon. The activated carbon adsorpted gold is washed with HC1 and NH4HF2, and meantime some impurities in it are removed. The results of this method are in conformity with the those of fire assaying. But the method is characterized with a low analytical cost, little pollution, fast analysis and relative standard deviation less than 1.20 % . |
