Recovery method of trace metal ions in aqueous solutions as nano-particles by reversed micellar extraction

将纳米级反胶束分子组装用于液-液萃取金属离子，同时利用反胶束作为反应中心制备纳米粒子。目标金属离子可以从含有许多金属离子作为杂质的水溶液中提取并转化为其纳米粒子。此外，通过阴离子表面活性剂和分子萃取剂的组合，在不降低目标金属离子浓度的情况下，成功地控制了反胶束的尺寸。

Nanometer-sized molecular assembly of reversed micelles was used for liquid-liquid extraction of metal ions and utilized as a reactive site to produce nano-particles at the same time. A target metal ion can be taken from an aqueous solution containing many metal ions as impurities and transformed into its nano-particle. In addition, the size of reversed micelles was successfully controlled without decreasing concentration level of the target metal ion by the combination of an anionic surfactant and a molecular extractant.
