Biosorption textile wastewater employing lemon peel derivatives: data analysis and kinetic modeling

The present work aimed to evaluate the efficiency of an agro-industrial waste biosorbent in removal real textile wastewater. A model sample with methylene blue and remazol golden yellow at equimolar proportions was prepared be treated natura, carbonized, activated lemon peel beads. Activated demonstrated superior capacity rates. Characterization analyses investigated morphology physico-chemical properties biomaterial. pH (2.0) dosage (1.6 g.L-1) studies were carried out select parameters for further studies. In kinetic assays, equilibrium reached faster than RNL. fitting indicated Elovich describe biosorption dye while pseudo-first-order fit best data. intraparticle diffusion that more one step may limit kinetics. treatment wastewater, 94.22% dyes attained after 360 minutes operation selected operational conditions. Kinetics adsorption wastewater presented considerable models R² greater 0.93. An artificial neural network developed satisfactory (R2 = 0.990).
