Biosorption of Acid dye by Jackfruit Leaf Powder: Isotherm, kinetics and Response surface methodology studies

A green adsorbent derived from Jackfruit leaf powder (JLP) was used to eliminate Acid Yellow 99 (AY 99) dye an aqueous medium in this study. We checked the effect of pH, biomass dosage, and temperature (process parameters) on adsorption potential AY explored using CCD model integrating RSM approach. At a pH 2.5, biosorbent dosage 4 gL-1, 30°C temperature, maximum removal preferred. ANOVA incorporated observe importance experimental variables their interactions. The solution (A) dose (C) had greatest effects decolorization 99, according findings. identify most important factors, which included two independent (A C) quadratic terms (A2 C2). kinetic data were effectively interpreted pseudo 2nd order with film diffusion combination, indicating chemisorptions phenomenon. Following Langmuir isotherm, utmost capacity for determined be 418.15 mg g-1 initial concentration. findings showed that JLP could employed as useful its medium.
