The effect of cation–π interactions in electrolyte/organic n

发布时间：2024-07-05 05:07

　　The rejection properties of a nanofiltration organic membrane were investigated using KCl solutions,NaCl solutions,NaCl/benzyl alcohol hybrid solutions and KCl/benzyl alcohol hybrid solutions.The presence of benzyl alcohol(3.7 mol · m^-3)caused a decrease in electrolyte rejection within the range of 0 to 6%.The mechanism of the decrease was discussed.The cation–π bond was assumed to form in the hybrid solution and to further induce the partial dehydration of the cation.The steric and c...
