液一液萃取在适当的条件下,能把高度选择性跟富集微量物质的能力,以及从大量复杂组份中分离其中少量组份的能力相结合.往往有可能找到这样的条件,仅需一次萃取就可以专一地并基本上定量地从混合物中将某一特殊成份分离出来.对于处理大量样品来说,它比沉淀法也显得更为容易.

Liquid-liquid extraction, under appropriate conditions, combines the high degree of selectivity with the ability to concentrate trace materials and the ability to separate small amounts of a large number of complex components. It is often possible to find such conditions that only A single extraction allows for a specific and essentially quantitative separation of a particular ingredient from the mixture, which is easier than the precipitation method for handling large numbers of samples.
