- Abstract
The thin-film composite membrane is aptly named as thin polyamide layer on the asymmetric polysulfone membrane. These membranes have salt rejection abilities, and the order is NaCl > CaCl2. Addition of NaCl increases (17.39% for 500 mg/L for Memb-II), whereas CaCl2decreases (5.94% for 500 mg/L for Memb-II) atrazine separation. Surfactant-mediated filtrations showed mixed results. Sodium lauryl sulfate (SLS) results better atrazine separation. SLS (200 mg/L) increases 29.72% separation for Memb-II. Contrary to SLS, Cetyl trimethyl ammonium bromide shows little negative influence (10.91%) and for Triton-X-100 (19.3%) it shows more deterioration effect for the same membrane, keeping the same concentration.
