Özet

Current study aimed to utilize agricultural waste, wheat husk to produce valuable materials. Amorphous silica (similar to 88 % purity) was extracted from acid leached wheat husk, and used in the synthesis of zeolite NaA. Crystallization factors were analysed at different temperatures (40-100 A degrees C) and durations (1-3 days) without using template. Crystallization conditions showed slight effects on the structural properties of the final product. The wheat husk silica based zeolites had a BET surface area and particle size ranging from 0.48 to 1.21 m(2) g(-1) and 0.60 to 3.00 A mu m, respectively. Results indicated that the wheat husk silica can be used to produce advanced materials for various industrial purposes.
