Experimentally and theoretically approaches for Congo red dye adsorption on novel kaolinite-alga nano-composite

A comprehensive study combining experimental, computational, and field experiments was conducted to find out the most suitable catalysis method assist industries using Congo red dye get rid of this waste from industrial wastewater in Beni-Suef area. The adsorption potential kaolinite, Liagora farinose (Egyptian marine macroalgae) kaolinite modified by macroalgae assessed for removal aqueous solutions. kaolinite/alga nano-composite with a crystal size 40 nm fabricated wet impregnation technique. Our results indicate that surface modification kaolin an obvious increase toxic than individuals. Batch were applied both kinetics isotherms also explored order influence different experimental factors. percentage is highly affected adsorbent dose, working temperature, pH value. best temperature onto 40°C at > 7. maximum capacities found be 5.0, 7.0 10 mg/g alga nano-composite, respectively. Computational simulations studies have shown molecule on Kaolinite surfaces exothermic, energetically favourable spontaneous. well handled first-order diffusion model, while follow two kinetic models depending concentration. Finally, tests showed optimistic nearly 94% efficiency removing mixed dyes wastewater, which turn verified foundation new eco-friendly nano-adsorbents help reuse wastewater.
