摘  要：
用微波消解法对空气滤膜和废气滤筒进行前处理,通过电感耦合等离子体发射光谱法测定了铬、铜、镍的浓度,并对测定结果进行了分析。结果表明,对空气样品中铬、铜、镍分析时微波消解法的检出限分别为0.006μg/m3、0.003μg/m3、0.04μg/m3,精密度分别为1.5%、3.2%、3.5%,加标回收率分别为104%、105%、103%。对废气样品中铬、铜、镍分析时,微波消解法的检出限分别为2.0μg/m3、0.8μg/m3、1.0μg/m3,精密度分别为3.5%、4.4%、4.3%,加标回收率分别为104%、107%、106%。同时对有证滤膜进行了测定,结果均合格。微波消解法测定的铬、铜、镍含量有较好的检出限、精密度和准确度,与电热板消解法不存在显著性差异,均适用于空气和废气颗粒物中的铬、铜、镍的测定。

摘  要：
The air filter membrane and exhaust gas filter cartridge were pretreated by microwave digestion,and theconcentration of chromium,copper and nickel was determined by inductively coupled plasma atomic emission spec-trometry,and the results are analyzed.The detection limits of microwave digestion in the analysis of chromium,cop-per and nickel in the air samples were 0.006,0.003,and 0.04 g/m3 respectively,and the precision was 1.5%,3.2%and 3.5%,respectively,and the recovery rates were 104%,105% and 103%,respectively.The detection limits of themicrowave digestion method for the analysis of chromium,copper and nickel in the waste gas samples were 2,0.8,and 1 g/m3 respectively,and the precision was 3.5%,4.4% and 4.3% respectively,and the recovery rates were104%,107% and 106%,respectively.Meanwhile,the measured results of certified filter membrane were all qualified.It is found that the content of chromium,copper and nickel determined by microwave digestion method has good de-tection limit,precision and accuracy,and there is no significant difference from the electrothermal plate digestionmethod.It is suitable for the determination of chromium,copper and nickel in air and waste gas particles.
