导数极谱法测定硫酸锰中的微量铅
Determination of Trace Pb in Manganese Sulphate by Micro Lead
【摘要】 在硫酸锰样品中,直接加入盐酸-氯化钠混合底液,铅产生一个良好的还原波,峰电位在-0 6V,在示波极谱仪上可直接用导数极谱法测定,该法简便、快速,回收率95 35%~100 50%,相对标准偏差2 09%~4 07%。
【Abstract】 In the sample of Manganese Sulphate, the mixture of hydrochloric acid-sodium chloride is added in. Lead will produce a fine returning ware. The highest-electricity power position is at-06 V. Derivative polarographic way can be directly used in the determination of oscilloscope polarographic instrument. This way is simple and quick. And the recycling rate is 9535%~10050% as well. Only the loss of the relative level is within 209%~407%.
