Journal ArticleDOI
A simple method for production of pure silica from rice hull ash
TL;DR: A simple method based on alkaline extraction followed by acid precipitation was developed to produce pure silica xerogels from rice hull ash (RHA), with minimal mineral contaminants as discussed by the authors.
Journal ArticleDOI
An improved method for production of silica from rice hull ash.
TL;DR: The improved method involved production of silica aquagel by adding silicate solution to pH 1.5 hydrochloric, citric, or oxalic acid solutions until the pH 4.0 was reached and silica xerogels produced by the improved method had sodium content of 0.52% and 0.22%, respectively.
Journal ArticleDOI
Silica gel from rice hull ash : Preparation and characterization
Savita R. Kamath,A. Proctor +1 more
TL;DR: In this article, a method to recover silica from rice hull ash and produce silica gel, and to determine the physical and chemical properties of the rice hull silica Gel (RHSG) relative to Trisyl 300, was developed.
Journal ArticleDOI
Adsorption of soy oil free fatty acids by rice hull ash
A. Proctor,Sevugan Palaniappan +1 more
TL;DR: In this article, it was shown that free fatty acids can be adsorbed from a soybean oil/hexane miscella by inorganic rice hull ash, and that a 1% dose was effective in diminishing free fatty acid concentrations but acid activation reduced the adsorption.
Journal ArticleDOI
X-ray diffraction and scanning electron microscope studies of processed rice hull silica
TL;DR: The structure and composition of processed rice hull ash were studied to better understand its adsorption of the soy oil components, lutein and free fatty acids as discussed by the authors, and the silica-rich ash was composed largely of low order cristobalite and tridymite in the form of opal CT, with variable particle size.
