| 中文摘要: |
| 采用过滤法与吸收法联用的采样方法，测定燃煤电厂烟气中Pb，并通过试验考察4种不同的吸收液和4种不同采样流量对测定的影响。结果表明：01 mol/L HNO3、〖JP3〗体积分数为5%的HNO3+10%的H2O2和体积分数为16%的HNO3+〖JP〗25%的HCl 3种吸收液均对Pb起到良好的捕集作用，且测定结果相近。采样流量控制在20 L/min吸收效果最好。 |

| Pb emissions in the flue gas from coal fired power plant were determined by combining the sampling methods of filtration and absorption. The testing effectiveness of 4 kinds of absorbent and 4 sampling flows was studied through experiments. The results showed that 3 kinds of absorbent， including 0.1 mol/L HNO3， 5% V/V HNO3+10% V/V H2O2 and 1.6% V/V HNO3+2.5% V/V HCl， had good absorption effects， and the results were similar. The absorption effect was the best when the sampling flow was 20 L/min. |
