摘要
以ＺＹＭ混合溶剂为萃取剂，对含４．５％甲酸的废水进行萃取试验，结果表明，ＺＹＭ具有良好的热稳定性和再生性，对废水中的甲酸有较高的萃取率。采用本萃取技术，不但具有显著的环境效益，而且还可回收甲酸，获得较好的经济效益。
A test for extracting 4.5% of formic acid in wastewater with a mixed solvent (named ZYM)has been carried out. The result shows that ZYM has a good thermostability and can be regenerated with a high extraction efficiency for formic acid contained in wastewater.The process can eliminate environmental pollution via recovering formic acid from wastewater with better economic benefit.
