The present study aims to investigate the dye decolorization efficiency of brown seaweed Dictyota bartayresiana against reactive blue 19 (RB19) dye. process variables namely and biosorbent concentration, pH incubation time were optimized through BBD based RSM for achieving enhanced decolorization. experimental data well fitted into Freundlich isotherm proving heterogenous adsorption RB19. Temkin Dubinin – Radushkevich models showcased endothermic chemisorption mediated RB19 onto D. bartayresiana. pseudo second order kinetic model exhibited assisted Weber Morris proved that intra particle diffusion was not rate limiting step in Thermodynamic studies revealed spontaneous, feasible biosorption. Interaction between assessed UV-Vis, FT-IR SEM which confirmed Desorption regeneration 73% desorbed first cycle using 0.1 M NaOH as eluent with 68% reduced subsequent cycles highlighting reusability biosorbent. Toxicity assessments untreated treated solution examined on microflora, brine shrimp fenugreek results nontoxic nature solution. Thus, this provides valuable insights utilization an eco-friendly affirms its safe use various biological applications.
