RSM-CCD design of volcanic ash/ rice husk ash based phosphate geopolymer for crystal violet adsorption: kinetics and isotherms

Abstract In this work, the application of central composite design (CCD) was used to optimise the synthesis of volcanic ash/ rice husk ash-based phosphate geopolymers. The effects of three factors namely, volcanic ash fraction, rice husk ash fraction and phosphoric acid concentration on porosity str...
