Abstract Tetramethylurea (TMU) is a good solvent for organic substances and has received little attention
as compared to other solvents. The TMU is a polar solution and is one of the molecules with an
amphiphilic character. In the present work, an attempt has been made to use TMU as an
additive in the preparation of nanofiltration membranes to improve the hydrophilicity of the
membrane. The polysulfone membrane has been modified by incorporating different
concentrations of TMU (0, 0.5, and 1 wt.%) in order to check the rejection of atrazine in water.
