Established by the air collecting environmental microporous membrane in copper, microwave digestion of the membrane, the method for determining the flame atomic absorption method. In the sampling volume was 60 L, the minimum detectable concentration of copper was 0. 008 mg/ m3 , the recovery was 94% ~ 103. 3% . This method was effectively to control losses and contamination of the sample digestion method, high efficiency, less dosage of acid, small environmental pollution, sample blank value was low, which could meet the environmental monitoring of copper in air analysis.
