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。
吹掃捕集—氣相色譜法能很好地滿足地錶水、廢水中吡啶的分析要求,具有前處理簡單、對設備要求低、抗榦擾能力彊的優點,且有良好的線性關繫,相關繫數達到0.999以上,相對標準偏差為1.3%~4.1%,加標迴收率為80.1%~99.7%,方法檢齣限為0.015 mg/L。
취소포집—기상색보법능흔호지만족지표수、폐수중필정적분석요구,구유전처리간단、대설비요구저、항간우능력강적우점,차유량호적선성관계,상관계수체도0.999이상,상대표준편차위1.3%~4.1%,가표회수솔위80.1%~99.7%,방법검출한위0.015 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.
