homogeneous liquid–liquid extraction 是什么啊？

| homogeneous liquid–liquid extraction 是什么啊？翻译过来好像是均相液液萃取，哪位童鞋可不可以给我解释一下呀？它的萃取过程？要优化哪些参数？ |

给找出文献中的解释，你看看！ Homogeneousliquid–liquidextraction is a simple and powerful preconcentration method that reduces the extraction time, disposal costs, consumption and exposure to the organic solvents. This method extracts the solute in a homogeneous solution into the very small sedimented phase formed from the solution by the phase-separation phenomenon. The ternary component solvent system and the perfluorinated surfactant system are the two usual modes of homogeneousliquid–liquidextraction. In homogeneousliquid–liquidextraction, the initial condition is homogeneous solution, namely, there is no interface between the water phase and the water-miscible organic solvent phase. In other words, the surface area of the interface is infinitely large initially. Accordingly, no vigorous mechanical shaking is necessary. The procedure is simple and requires only the addition of the reagent 这里有两篇温馨啊，里面有具体的方法，操作，你可以看看！ http://115.com/file/bevnst2a#b001581o.pdf http://115.com/file/e7x1qsl2# 1-s2.0-S0003267007008744-main.pdf |
