Removal of Carbamazepine onto Modified Zeolitic Tuff in Different Water Matrices: Batch and Continuous Flow Experiments

Carbamazepine (CBZ) is the most frequently detected pharmaceutical residues in aquatic environments effluent by wastewater treatment plants. Batch and column experiments were conducted to evaluate removal of CBZ from ultra-pure water plant (WWTP) using raw zeolitic tuff (RZT) surfactant modified zeolite (SMZ). Point zero net charge (pHpzc), X-ray diffraction (XRD), fluorescence (XRF), Fourier Transform Infrared (FTIR) investigated for adsorbents physiochemical changes resulted modification process Hexadecyltrimethylammonium bromide (HDTMA-Br). XRD FTIR showed that RZT has created an amorphous surface with new alkyl groups on surface. The pHpzc was determined be approximately 7.9 SMZ. results indicated uptake SMZ higher than all sorption tests (>8 fold). capacity WWTP (0.029 0.25 mg/g) (0.018 0.14 ultrapure (1.6–1.8 equilibrium time matrix (47 h) much longer water. & (0.03, 0.33 (0.02 0.17 (1.5–2 fold) test.
