摘要
随着我国城镇污泥处理技术不断发展,汞的安全性检测至关重要。通过连续浸提-原子荧光光度计测定污泥中汞形态,结果显示汞元素各形态在本实验条件下线性良好,检出限低,RSD在1.4%~7.8%,加标回收率在72.0%~122%,具有较强的适用性,可以为标准CJ/T 221—2023《城镇污泥标准检验方法》在后续修订过程中对于汞形态的测定提供参考。
With the ongoing advancement of urban sludge treatment technologies in our country,the safety assessment of mercury is of paramount importance.The determination of mercury species in sludge is conducted through continuous extraction followed by atomic fluorescence spectrometry,the results showed that the mercury species had good linearity under the experimental conditions,with low detection limits,RSD ranging from 1.4%to 7.8%,and spiked recovery rates ranging from 72.0%to 122%.It has strong applicability and can provide a reference for the determination of mercury species in the subsequent revision of the standard CJ/T 221—2023"Standard Test Methods for Municipal Sludge".
