摘要
采用离子色谱法测定废气中的丙烯酸,几种常见的无机阴离子对分析无干扰。方法在0.100 mg/L～10.0 mg/L范围内线性良好,对有组织废气和无组织废气的检出限分别为0.04 mg/m3和0.003 mg/m3,废气平行样品测定值的相对偏差为3.4%～10.5%,加标样品的回收率为91%～102%。
Acrylic acid in exhaust was determined by using ion chromatography. The common inorganic ani- on did not produce interference to the sample analysis. Calibration curves for acrylic acid of the method exhibited linearity in a range between 0. 100 mg/L and 10.0 mg/L. Detection limits were 0.04 mg/m3 for controlled emis- sion and 0. 003 mg/m3 for uncontrolled leakage. The RSD of duplicated exhaust samples ranged from 3.4% to 10.5%. Spiked recoveries of samples ranged from 91% to 102%.
