The raw materials, auxiliary materials and production process of a typical copper smelting factory were investigated, the emission characteristics of exhaust gas pollutants produced by the production process were studied. To test the samples by graphite furnace, firstly in order to unify the digestion system in the experiment, the applicability of three different method was verified by experiments. According to the results, the recovery of nitric acid-perchloric acid digestion system is a relatively good, so it can be recommended. The testing results show linear range, detection limit and detectability of the method could meet the requirements of environmental monitoring.
