For the development of the closed extraction process of phosphorus from soil with acid / alkali solution the extraction equilibrium of phosphorus and the bipolar membrane system were studied. Phosphorus was extracted under pH 2 and above pH 11 regardless of kind of acid / alkali used for the extraction, which were HCl, HNO3, H2SO4, NaOH, KOH, NH3aq. In the acid condition the phosphorus was extracted with Al, Ca, Fe and in the alkali condition phosphorus was extracted with Al. It was demonstrated that the bipolar membrane system, which was a closed process for producing both acid / alkali from salt, was useful for the extraction phosphorus from soil.

为开发酸/碱溶液密闭萃取土壤中磷的工艺，对磷的萃取平衡和双极膜系统进行了研究。在pH 2和pH 11以上的条件下，无论用于提取的酸/碱的种类是HCl、HNO 3、H2SO 4、NaOH、KOH、NH3 aq，磷都被提取。在酸性条件下，磷被Al、Ca、Fe萃取，在碱性条件下，磷被Al萃取，表明双极膜系统是一种从盐中产生酸/碱的封闭过程，适用于土壤中磷的萃取。
