Abstract

The effect of both citric acid and hydrochloric acid on the Si-K-HAs gel characterization was studied with various pH gelation. The Si-K-HAs gel obtained from acidification of the mixture of potassium silicate and potassium-humic substance solution by polymerization process. The humic substance was obtained from peat extraction while silica obtained from geothermal sludge extraction, both using potassium hydroxide solution as solvent. The volume ratio of potassium silicate to humic substance solution studied in the range of 1:1, 1:2, 1:5 dan 1:10. The Si-K-HAs gel dried and powdered samples were characterized by IR spectra, X-ray diffraction, and SEM-EDX. The different of type of acid caused the composition and characteristic of Si-K-HAs on product also difference.
