Coconut husk as potential sources for silica production


Anuar, Muhammad Fahmi and Yap, Wing Fen and Mohd Zaid, Mohd Hafiz (2018) Coconut husk as potential sources for silica production. In: 2nd International Symposium on Advanced Materials and Nanotechnology (i-SAMN 2018), 15-16 Aug. 2018, The Everly Putrajaya, Malaysia. (pp. 26-27).

Abstract / Synopsis

Silica can be extracted from agriculture waste. In this study, the waste coconut husk (CH) burned in controlled environment inside electrical furnace at temperature of 700 °C. These ashes were chemically treated by using two different methods of extracting silica. XRF analysis of coconut husk ash revealed that the content of SiO2 varies between 8-11 % and increased up to 90 % after chemical treatment. XRD analysis indicates that silica obtained after acid treatment was in crystalline state while by using alkali treatment it was in amorphous state.
