Optimization of Remazol Black B Removal Using Biochar Produced from Caulerpa scalpelliformis Using Response Surface Methodology

Optimization of process conditions for the removal Remazol Black B was investigated using response surface methodology (Box–Behnken design). The biodecolorization dye studied biochar produced from waste biomass Caulerpa scalpelliformis (marine seaweeds). reactions were optimized by varying sorbent dosage, solution pH, temperature, and initial concentration. results indicated that efficiency 80.30% attained at an operating condition 4 g/L (sorbent dosage), 2.0 (solution pH), 35°C (temperature), 0.25 mmol/L (initial concentration). regression coefficient developed model calculated to be 97% which shows good fit model.
