該研究團隊利用理論計算方法對苯氧乙酸及其二聚體的結構及氫鍵二聚體鍵能進行了優(yōu)化計算，利用分子中的原子理論對稀土和苯氧乙酸的官能團成鍵強度進行了分析(Ind.Eng.Chem.Res.,2016，DOI:10.1021/acs.iecr.6b01077)。該研究有助于為新型萃取劑的設計和優(yōu)化提供理論指導。在此基礎上，該研究團隊針對現(xiàn)有稀土分離工藝存在的問題，開展了離子液皂化研究(ACSSustain.Chem.Eng.,2016，4,1573-1580)，這一新型技術有助于避免傳統(tǒng)皂化工藝中大量酸堿消耗及皂化廢水。研究表明，離子液協(xié)同萃取過程中的反膠團可有效提高稀土的萃取效率(AIChEJ.,2016,62,2163-2169)，此類協(xié)同體系在吸附材料中的協(xié)同因子顯著高于液液萃取(ACSSustain.Chem.Eng.,2016,4，616-624)。在現(xiàn)有研究工作基礎上，該團隊開展的工業(yè)試驗正在順利進行。
