微库仑法测定污泥中可吸附有机卤化物(AOX)
|
摘要
建立了一种污泥样品中可吸附有机卤化物的测定方法。通过HNO_3-NaNO_3-活性炭体系震荡提取污泥中的有机卤化物,采用微库仑法测定AOX含量。结果表明,该法精密度和准确度较好,加标回收率达到95.6%,精密度RSD2.1%～3.1%。本法是测定污泥样品中可吸附有机卤化物的高效方法。
A method for determination of adsorbable organic halogens(AOX) in sludge samples was established. Organic halogens in sludge samples were shocked and extracted by nitric acid-sodium nitrate-activated carbon, and the halogens were determined by microcoulometry. Results showed that accuracy and precision of this method were good, the recovery ratio amount to 95.6% and the RSD range from 2.1% to 3.1%. this method for determination of AOX in sludge samples is efficent.
