Removal of Cresol Red by Adsorption Using Wastepaper

The utilization of less expensive and more effective adsorbents derived from a variety basic materials has been investigated. research aimed to investigate the feasibility employing waste paper as adsorbent remove cresol red (CR) dye wastewater through adsorption mechanism. Langmuir, Jovanovic, Freundlich model were observed for isotherms models, while pseudo-first-order pseudo-second-order examined kinetic models. results indicated that increasing dose contact time gave no significant effect capacity increased with pH until it reached maximum at 8, raising starting concentration leads in increase (16.7 mg/g). When experimental fitted using models model, was discovered those accurately represented by data, high correlation coefficient (R2) 0.974 0.963.
