汞是剧毒元素,尿汞是诊断汞中毒的一个生化指标。目前,尿汞的测定多用双硫腙法和冷原子吸收法,原子吸收法、阳极溶出法也有报道。本文采用镀金膜电极微分电位溶出法测定尿汞,样品处理简单,简便易行,干扰小。试验部分一仪器与试剂MP-1型微分电位溶出分析仪(山东电讯七厂)
Mercury is a highly toxic element and mercury in urine is a biochemical indicator of mercury poisoning. At present, the determination of urinary mercury and more with dithizone method and cold atomic absorption method, atomic absorption method, anodic dissolution method has also been reported. In this paper, gold-plated membrane electrode differential potentiometric stripping method for the determination of urinary mercury, sample processing is simple, simple and easy to use, small interference. Experimental part of an instrument and reagent MP-1 differential potentiometric dissolution analyzer (Shandong Telecom seven plants)
