Conversion of rice husk ash to zeolite beta
Waste Management, 2006White rice husk ash (RHA), an agriculture waste containing crystalline tridymite and alpha-cristobalite, was used as a silica source for zeolite Beta synthesis. The crystallization of zeolite Beta from RHA at 150 degrees C in the presence of tetraethylammonium hydroxide was monitored by XRD, FTIR and (29)Si MAS NMR techniques. It was found that zeolite

Preconcentration of gold by rice husk ash
Minerals Engineering, 2000Abstract The goal of this research was to develop a new, efficient adsorbent of gold-thiourea complex, [Au(CS(NH 2 ) 2 ] + . In this experiment, rice husk was heated at three different temperature: 300°C, 400°C and 500°C. Rice husk ash heated at 300°C adsorbed gold thiourea complex, whereas rice husk ash heated at 400°C and 500°C did not.

Use of rice husk ash in concrete
International Journal of Cement Composites and Lightweight Concrete, 1984Abstract Rice husk ash was prepared as a pozzolana by a special process such that the final product conformed to engineering requirements in terms of physical and chemical properties, and the silica remained in an amorphous form with a minor amount of unburnt carbon.

Rice-husk (RH) is an agricultural by-product material. It constitutes about 20 % of the weight of rice. It contains about 50 % cellulose, 25–30 % lignin, and 15–20 % of silica. When rice-husk is burnt rice-husk ash (RHA) is generated. On burning, cellulose and lignin are removed leaving behind silica ash.

Study on concrete with rice husk ash
Innovative Infrastructure Solutions, 2018Rice husk ash (RHA) possesses high pozzolanic activities and very suitable as partial replacement of cement in concrete. This paper presents a comparative study on use of RHA as partial replacement of cement in concrete specimens. Review of the researches on physical, mechanical and structural properties of concrete containing RHA as partial ...

Removal of humic acids from synthetic wastewater by rice husk ash and modified rice husk ash
In this study, titanium dioxide was loaded with chromium together with either platinum or rhodium in attempt to improve its photocatalytic activity for water splitting. Titanium dioxide was synthesized via a sol-gel method and the metals were loaded by incipient wetness impregnation technique. The amount of chromium added was varied between 0 to 1 % (w/openaire +1 more source
