Effect of Brij 35 and saponin surfactants on adsorption of diethylstilbestrol as anemerging estrogenic contaminant by clinoptilolite in batch and fixed-bed columnexperiments
Abstract:In this study, natural clinoptilolite was modified by saponin and Brij 35 surfactants to remove diethylstilbestrol (DES) from wastewater in batch and continuous systems. The optimum pH, amount of adsorbent, contact time, and temperature were 11, 10 g/L, 12 h, and 35°C, respectively, for the process. The equilibrium data agreed well with the Langmuir isotherm for natural clinoptilolite (NC), natural clinoptilolite modified by Brij 35 (NC-Brij), and natural clinoptilolite modified by saponin surfactants (NC-sapo… Show more
