Performance Test of Gelcasted Porous Ceramic as Adsorbent of Azo Dyes

Abstract

Has been done a research about performance test of gelcasted porous ceramic as adsorbent of azo dyes. The method of synthesis porous ceramic used was gelcasting method. The monomers used was acrylamide (AM) with crosslinkers was methylenbisacrylamide (MBAM). The polymer formed acts as a pore template. Variation of AM:MBAM ratio used at 6:1; 12:1; 18:1; 24:1. Characterization of gelcasted porous ceramic carried out were the density, porosity, morphology, and percent adsorption of ceramic to azo dyes. The results showed that the lowest density occurred at ratio 6:1 of 15.82 g/cm3 with the highest porosity of 36.86 %. The morphology test indicated the presence of open and closed pores in the ceramic body. The highest adsorption percentage occurred at the ratio 6:1 against to congo red, acid orange, and direct blue with adsorption percentage respectively 39.72%; 48,38%; 32,26%.
