摘要:
选用对氯苯酚固体和市售对氯苯酚标准溶液分别配制成2种可吸附有机卤素(AOX)标准溶液和标准样品进行实验。结果表明,使用对氯苯酚固体配制的AOX标准溶液,其分析曲线和带标分析结果良好,检出限为6.6 μg/L,加标回收率为80.1%~106%;使用市售对氯苯酚标准溶液配制的AOX标准样品,其测定结果均在参考不确定度范围内,加标回收率为94.0%~103%,测定值与真值的相对误差为-6.0%~2.5%。可见,选用对氯苯酚作为标准物质和标准样品应用于环境地表水和工业废水中AOX监测分析的质控过程是可行的。

Application of P chlorophenol in Water Environmental Monitoring of Absorbable Organic Halogens
DOU Yan-yan, WANG Bao-qin
Abstract:
In this study, solid p chlorophenol and commercially available standard solution and standard sample of p chlorophenol were used to prepare reference materials in absorbable organic halogens (AOX) determination. The results showed that both the analyzing curve and the reference material’s results were satisfactory using the self prepared AOX standard solution. The detection limit of this method is 6.6 μg/L with spiked recovery ranging from 80.1% to 106%. All the measurements fall into the acceptable limits using the reference material prepared from commercially available standard solution of p chlorophenol, and the spiked recovery ranged from 94.0% to 103%,the relative error between the measured value and the true value ranging from -6.0% to 2.5%.Therefore, it is feasible to use p chlorophenol as the reference material for AOX analysis on surface water and industrial waste water.
