Pengaruh Rasio Sio2/Na2o Dan H2o/Na2o Terhadap Bola Geopolimer Berpori Berbahan Dasar Pofa (Palm Oil Fly Ash) Sebagai Adsorben

---

ABSTRACT
Palm Oil Fly Ash (POFA) is a solid waste from palm oil that has a high silica and alumina content. This shows that POFA can be used as a raw material for making geopolymers. Geopolymers are polymers made from non-organic natural materials. Geopolymers have the potential to be used as adsorbents in both powder and spheres form. This study aims to analyze the effect of the SiO2/Na2O and H2O/Na2O ratios on the porous geopolymer spheres as adsorbents and to test their adsorption capacity on peat water. Porous geopolymer spheres were synthesized with a SiO2/Na2O ratio of 2.4; 2.7; 3 and a H2O/Na2O ratio of 12, 14, 16. Characterization of porous geopolymer spheres was carried out using XRF, XRD, FTIR and BET tests. The highest dye removal result obtained was 82,71% with an adsorption capacity of 15.98 mg/g, surface area of porous geopolymer spheres is 23,365 m2/g, the total pore volume is 0,087cm3/g, and the average pore size is 7,406 nm.
Keywords: Adsorption, H2O/Na2O ratio, Palm Oil Fly Ash (POFA), peat water dyes, porous geopolymer spheres, SiO2/Na2O ratio.
