摘要
吹扫捕集—气相色谱法能很好地满足地表水、废水中吡啶的分析要求,具有前处理简单、对设备要求低、抗干扰能力强的优点,且有良好的线性关系,相关系数达到0.999以上,相对标准偏差为1.3%~4.1%,加标回收率为80.1%~99.7%,方法检出限为0.015 mg/L。
Purge and trap-gas chromatography can satisfy analysis requirements of pyridine in the surface water and waste water,has a simple pretreatment equipment requirements low,the advantages of strong anti-jamming capability,and there is a good linear relationship.The correlation coefficient is up 0.999,the relative standard deviation is 1.3% to 4.1%,the recovery rate is 80.1 percent to 99.7 percent,and the detection limit is 0.015 mg/L.
