摘要
在废干电池利用中需要准确测定汞含量。研究了在酸性条件下,采用双硫腙萃取滴定法测定汞含量,并对铁锰锌的影响、浸出酸的影响、硫化铵除汞的效果等进行了试验。结果表明,该法操作简单、结果可靠。
The content of hydrargyrum needs to be determined accurately in the use of waste dry battery. In this research the content of hydrargyrum is determined using dithizone titration-extraction method in the acidic condition. Meanwhile, the effect on iron, manganese, zinc and acid leaching, as well as the effect of ammonium sulfide on the hydrargyrum removal is tested. The results show that this method is simole and reliable.
