摘要

Textile industry produces huge amounts of wastewater containing synthetic dyes and impurities. Contaminants include toxic dyes, which can be found in dyeing wastewater. In textile industry, various dyes such as acid, basic, reactive, disperse are used for dyeing. The aim of this study was to evaluate adsorption of Acid Blue 74 by electrospun PA-6/Modified zeolite nanofibrous composite. Design of the Response Surface Method (RSM) of Box-Behnken model (BBD) was used to determine the optimal conditions for the removal of Acid Blue 74. The effect pH, temperature, stirring speed, dye concentration, and adsorbent dose were investigated. The investigation of kinetic and isotherm model showed that the reaction kinetics follows the pseudo-second-order model and the PA-6/Modified zeolite nanofibrous composite adsorption process follows the Freundlich model. As a result, the PA-6/Modified zeolite nanofibrous composites can be considered as an effective material in removing Acid Blue 74 from wastewater.
