Adsorptive Removal of Reactive Blue-23 (RB-23) from Aqueous Solutions by Low-Cost Adsorbent and Nano-Particle: Comparative Evaluation.

Abstract

The most difficult task is determined to be the treatment and disposal of wastewater from textile mills, particularly colored effluents. Researchers from all around the world have attempted to remediate dye effluents with nanoparticles and inexpensive adsorbents. The investigation conducted to assess the viability of extracting RB-23 from aqueous solution utilizing ZIV (nanoparticles) and rice husk, a low-cost adsorbent, under various experimental circumstances, is presented in this work. Additionally, an effort has been made to fit isotherm models to the experimental data. According to the analysis, the data, within the bounds of statistical significance, fit into both the Langmuir and Freundlich isotherms. Additionally, the data presentation and analysis showed that the pseudo second order kinetic model had a high correlation coefficient and corresponded extremely well with the experimental data. When testing under ideal circumstances, it has been shown that nanoparticles adsorb more color than Rice Husk.
