Modification of sago based membrane for pervaporation separation of cesium formate

Pervaporation separation process has been established as an important separation unit in chemical engineering. Pervaporation is widely used for dehydration o f aqueous mixtures and is expected to find further progress in organic/organic separation and the organic-water separation. In this study 3 di...
