In this study, the modified rice husk was tested to remove Cu(II) from water. Batch experiments were carried out to evaluate the adsorption characteristics of the modified rice husk for Cu(II) removal from aqueous solutions. The adsorption isotherms, thermodynamic parameters, kinetics, pH effect, and desorbability were examined. The results show that the maximum adsorption capacity of the modif...

Rice husk and sawdust were selected as the raw materials for a study of biomass char yield in the range of 600 to 900 °C. It was found that temperature was the primary factor affecting the biomass char yield. The yield of the rice husk and sawdust chars decreased significantly with increasing temperature. As the residence time increased, the biomass char yield decreased. The smaller the size of...

Asian countries rely massively on rice to feed and sustain its massive population. For long the staple food has provided nourishment masses classes. Rice is grown in large quantities countries. A by-product of cultivation husk. The husk grain mainly utilized as a fuel for boilers mills. uncontrolled burnt referred ash consists majorly silica. silica used wide variety commercial industrial appli...

Rice husk (RH) is a biomass resource that contains about 20 mass% silica. In Southeast Asia countries, RH used as fuel for thermal power plants, and it produces large amount of ash (Rice Husk Ash: RHA), industrial waste. Furthermore, our research group has reported consolidated zeolite A could be prepared from RHA raw material. Zeolite hydrophilic micropore in the structure adsorption builder d...
