This paper focuses on the functions of the elements such as the pH of solution, dosage of extraction solvent, dosage of salt, concentration of polymer, time of extraction.
主要讨论了溶液酸度、萃取剂用量、盐用量、聚合物浓度、萃取时间等因素的影响。
In here, in solution you have all these molecules of solvent, molecules of salt, molecules of acid, or whatever, pH that are going to be around to buffer the pH.
在这里，溶液里包含了所有这些溶剂分子，盐分子酸分子和其它东西，可以用来缓冲。
