Preparing Nanosilica Particles from Rice Husk Using Precipitation Method
نویسندگان
چکیده
Nanosilica was extracted from rice husk, which locally collected the Iraqi mill at Al-Mishikhab district in Najaf Governorate, Iraq. The precipitation method used to prepared powder husk ash, after treating it thermally 700°C, followed by dissolving silica alkaline solution and getting a sodium silicate solution. Two samples of final were study effect filtration on purity sample X-ray fluorescence spectrometry (XRF). result shows that filtered have above while non-filtered around structure analysis investigated diffraction (XRD), found has an amorphous nature. Also, broad peak ( particle size distribution determined Atomic force microscope (AFM), results gave average diameter equals dimension range , B.E.T. confirms high surface area 618 . FT-IR Spectra experimental data showed presence hydrogen-bonded silanol group (Si–O–H) siloxane (Si–O–Si) proved particles.

Consecutively Preparing D-Xylose, Organosolv Lignin, and Amorphous Ultrafine Silica from Rice Husk
Rice husk is an abundant agricultural by-product reaching the output of 80 million tons annually in the world. The most common treatment method of rice husk is burning or burying, which caused serious air pollution and resource waste. In order to solve this problem, a new method is proposed to comprehensively utilize the rice husk in this paper. Firstly, the D-xylose was prepared from the semic...
