Contribution to the Modeling of a Biosorbent Derived from Cocoa Pod Shells on the Methylene Blue Index

The objective of this study is to improve the preparation a biosorbent from cocoa pod shell by an experimental plan. shells underwent drying and grinding followed chemical impregnation with sodium hypochlorite. process was optimized based on analysis methylene blue index as function four factors: temperature, mass material, hypochlorite agitation temperature preparation. This plan reveals that under conditions varies 201.24 402.61 mg/g. Statistical data shows size factor strongly influences index. Also, interactions between have significant influence adsorption capacities biosorbent. application design amount hypochloride stirring preponderant effect model which adequate. optimal values for are 00 (X1), -0.6519 (X2), -1.0 (X3) (X4).
