Preparation of porous porous bodies by gelcasting method and the analysis of its properties using the response surface method to remove methylene blue from aqueous solution

Zeolite were formed through agar gelcasting method.Response surface methodology ( RSM ) is proposed as a  tool for rapidly optimizing the activation parameters in order to obtain the highest porosity of samples. 40 % of zeolite and 1 wt %  of agar was selected as optimal conditions. porous bodies with an optimal combination of 54.4% porosity , density 0.9 g / cm3 , and  compressive strength of 6.67MPa  were made  and  observed that there is a slight difference between predicted  values by the software and the measured values.  Longer time to mixing from 1 / 5 min to 3 min , the porous body has 67.17 % porosity , density 0.69 g / cm3 , and compressive strength of 5 / 3 MPa .XRD and SEM analysis was used  to investigate the  phase and structural changes at 800 C. The highest percentage of adsorption of methylene blue at 4ppm concentration after 72 h was 98.94 %.
