摘要
文章介绍了萃取法对湘潭电化的锰液（锰泥）的萃取与反萃取行为及实验效果的研究.室温下,采用P204的煤油皂化液为萃取剂,pH 3.5～4.0,皂液比为1∶2.0～2.5.经GB/T5750.6-2006方法分析,萃取率达98.2％.同时对水相酸度、萃取剂浓度、搅拌时间等因素对Mn2＋的萃取率的影响进行了研究.结果表明采用该方法能有效地回收锰,精处理的废液达到排放标准.
In the paper, electrification extraction and back extraction behavior and experimental effect on Manganese liquid from electrochemistry factory was studied. At room temperature, P2O4, used as extract agent to extract kerosene-liquid with a liquid soap ratio in 1 ： 2.0-2.5 at pH 3.5--4.0 at 98.2 % extract rate （analyzed by GB/T5750.6-2006 method.）. Simultaneously, acidity of aqueous phase, concentration of extract agent, extraction duration effects on the extraction rate of Mnz＋ is investigated. Results show that this approach can effectively recover Mn2＋, fine treat liquid waste meets the discharge standard.
