摘要
介绍了总有机卤素(TOX)的分类及可吸附有机卤素(AOX)的测定步骤,讨论了AOX测定过程中的影响因素,明确了吸附柱所用活性炭的技术要求和测定结果的计算方法。试验结果显示:对于纯水中AOX加标量为20μgC l-/L的水样,其平均回收率为99.5%;对于AOX加标量为100μgC l-/L的水样,平均回收率为97.6%;对于饮用水中AOX加标量为50μgC l-/L的水样,平均回收率为97.2%。试验结果表明,活性炭吸附/燃烧/微库仑滴定方法可准确测定水中AOX的含量。
The classification of total organic halogen （TOX） , the principal and detailed procedure for the determination of adsorbable organic halogen （AOX） were briefly introduced, and the influencing factors during the determination of AOX were also discussed. The technical requirement for the activated carbon used in the adsorption columns and the calculation method of the result were definitely expressed. The recovery results show that the average recovery is 99.5% at 20 μgCl^-/L AOX and 97.6% at 100 μgCl^-/L AOX in pure water as well as 97.2% at 50 μgCl^-/L AOX in tap water. The result indicates that the method combining activated carbon adsorption/combustion/microcoulometric titration is a reliable and accurate one for measuring AOX in water.
