Isothermal and thermodynamic study of the adsorption of coomassie brilliant blue G-250 dye from aqueous solutions by modification Iraqi Porcellanite Rocks

This study was incorporated (Iraqi Porcelanite Rocks alteration) Iraqi Porcelanite Rocks melamine formaldehyde polymer. Remove Coomassie Brilliant Blue G-250dye from fluid arrangement due to its strong adsorptive properties. pH, connect time, ionic strength, temperature, and Adsorbent mass were all investigated. The highest adsorption efficiency was recorded at was set at 99.00 %with 15 mg/L dye, 10 minutes contact time, 0.0050g of adsorbent, and 298 K. End information utilizing Temkin, Langmuir and Freundlich models were dissected at various temperatures going at, and the adsorption thermodynamic boundaries were contemplated. Where ΔG values demonstrate a programmed interaction, ΔH.
