以废TFT-LCDs面板酸浸液为研究对象，对其进行浓缩、萃取，分析回收铟过程中的影响因素。研究表明，随着浸出液浓缩倍数的增加，P204萃取In3+的能力下降。通过调整浓缩液酸度，In3+的萃取率可达99%以上。伴随In3+同步浸出的Fe3+、B3+、Al3+对铟萃取产生一定的影响，但是单一离子对萃取率的影响低于5%。

The influencing factors of indium extraction from waste TFT-LCDS lichant were analyzed in this article. The results showed that the extraction capability of P204 declined with the increase of concentration times of lichant. By adjusting the acidity of concentrated lichant , indium extraction rate could reach 99%. Fe3+、B3+、Al3+ in the lichant left impact on indium extraction, while the effect of each ion on indium extraction rate was below 5%.
