Abstract
The goal of the current work was to prepare magnetite/bentonite nanocomposite and testing for expulsion effectiveness of cationic methylene blue (MB) and anionic methyl orange (MO) dyes, phenol and Ni2+ from industrial wastewater in individual and combined systems. Batch experiments have been done to observe the best adsorption by altering various parameters such as temperature, pH, the dose of adsorbent, initial pollutants concentration and contact time. The results demonstrated that the optimum pH for removing (MB) was 9.0, (MO) was 4.0, phenol was 7.0 and 4.0 for Ni2+. The optimum concentration, temperature, contact time and adsorbent dose were 100 mg/L, 80 oC, 120 min and 1g of adsorbent, respectively. The sorption process was modeled utilizing Langmuir and Freundlich equations. The adsorption isotherm demonstrated a superior fit to Freundlich than Langmuir equation. The analysis was also modeled using the pseudo-first and second order equations. The pseudo-second-order equation gave better fit with an R2 value; 0.999 for all pollutants. This implies that our proposed magnetite\bentonite nanocomposite can be utilized as a cheap and excellent adsorbent for expulsion of cationic and anionic dyes, phenol and cationic heavy metal ions from industrial wastewater.
