Abstract
Permeation coefficients of urea and NH4 + across liquid membranes of glycerine esters were determined. The enzymatic hydrolysis of urea was chosen to show the selectivity of the membranes with respect to urea and ammonium ions. The mass transfer rate for urea was up to 15 times higher than for ammonium ions.Keywords
