Stripping agent is used in a liquid membrane system. A stripping agent is a chemical specie which is added to the product phase of a liquid membrane to react, in the membrane/product interface, with the target specie or with the complex target specie carrier, giving a membrane insoluble product or simply releasing the target specie in the product phase. In order to improve the effectiveness of the liquid membrane separation processes, by maximizing both the extraction velocity (flux through the membrane phase) and the reception capacity of the diffusing specie in the product phase, a stripping agent is added to the product phase. This agent quantitatively reacts, in the membrane phase/product phase interface, either directly with the diffusing specie to yield a membrane insoluble product, preventing it from diffusing back through the membrane (facilitated transport type 1), or with the complex formed between the target specie and a carrier (added to the membrane phase to transport...
