本文采用一种金属交换剂(metexchange),使铅从红细胞中释放出来,再用阳极溶出伏安法进行测定。由于本法不用对血样进行消化处理,不仅加快了分析速度,而且避免了消化血样时可能带来的污染或损失。 1.仪器及测试条件: AD-1型极谱仪(江苏金坛分析仪器厂),XWT-206型台式记录仪(10mV),CSF-50型超声处理机,工作电极:银基汞膜电极,参比电极:Ag/AgCl电极,富集时间:1分钟,扫描电压:
This article uses a metal exchange agent (metexchange), the release of lead from the red blood cells, and then determined by anodic stripping voltammetry. Because this law does not digest the blood sample, not only speeds up the analysis, but also avoids possible contamination or loss of blood samples when digested. 1. Instrument and test conditions: AD-1 polarographic instrument (Jiangsu Jintan Analytical Instrument Factory), XWT-206 desktop recorder (10mV), CSF-50 ultrasonic processor, the working electrode: silver-based mercury film electrode , Reference electrode: Ag / AgCl electrode, enrichment time: 1 minute, scanning voltage:
