Abstract

MANUFACTURE OF SILICA GEL FROM COCONUT WASTE WITH THE INFLUENCE OF EXTRACTION TIME AND SODIUM HYDROXIDE CONCENTRATION

*Kiagus Ahmad Roni, 2Elfidiah, Heni Juniar and Desi Andrayani

ABSTRACT

Silica gel is a material known for its high thermal and chemical stability, good selectivity and resistance, and can be used repeatedly so that it is more economically advantageous. So far, quartz sand is a raw material used in producing silica, but for the process of processing quartz sand requires a fairly high temperature, high cost, and a complicated process. Therefore, it is necessary to find alternative raw materials to obtain silica with a cheap and simple process. Coconut coir ash can be used as an alternative material that contains silica. This research was conducted to determine the effect of extraction time and concentration of NaOH on silica gel produced from coconut coir ash. In addition, the vapor absorption capacity at that condition was 800 mg/g.
