Coconut husk fibre and rice straw were found to be able to remove significant amount of Cr (III) ions from aqueous solutions. Its removal is a function of pH and concentration. The optimum pH range for maximum uptake is between 4 and 6 for both substrates. The adsorption capacity was found to be 0.55 and 0.30 millimole Cr (III) / g substrate for coconut husk and rice straw respectively. The ads...

Due to rapid growth in population and industrialization, some new technologies are made for waste utilization and cost reduction in industrial processing by using rice husk (lignocellulosic biomass) as a valued material. In this paper various industrial and domestic application of rice husk and rice husk ash are discussed. Rice husk act as adsorbent for removing heavy metals from wastewater. In...

This study was conducted to evaluate the properties of cement bonded particleboard made from rice husk and sawdust. Sawdust and rice husk fine boards were made using two ratios of cement and particles of 70:30 and 80:20, but rice husk coarse was made with a ratio of cement and particle of 80:20. The density of sawdust and rice husk fine boards in a ratio of cement and particles of 70:30 was 960...

Abstract Ammonium ions (NH 4 + ) are commonly found in contaminated water and a contributing factor to eutrophication. Carbonized rice husk, derived from various biomass sources, possesses porous structure, its characteristics influenced by the feedstock pyrolysis conditions. Hence, this study aimed investigate applicability of carbonized husk as an absorbent for NH removal. The adsorption kine...

In this study, adsorption of zinc onto the adsorbent (untreated rice husk and NaOH-treated rice husk) was examined. During the removal process, batch technique was used, and the effects of pH and contact time were investigated. Langmuir isotherm was applied in order to determine the efficiency of NaOH-treated rice husk used as an adsorbent. The zinc adsorption was fast, and equilibrium was atta...

Moving towards sustainable agriculture implies exploring the interconnections between farming and the environment, and soil is a key component of sustainability. Mulching is one of the methods to protect and enhance the productivity of the soil. We studied here the effect of mulching applied to mandarin tree rows for weed control in two localities near Tortosa, Spain, to compare its performance...

Using the mixture of carbonized rice husk and shungite from Kazakhstan Koksu deposit experimentally determined oil sorption capacity contaminated soil with originating in Karazhanbas field, a set Artificial Neural Network (ANN) models were built for predictions. The ANN architecture design, training, validation testing methodology performed, prediction was evaluated. successfully trained captur...

The present study was conducted to prepare dietary fiber rich chicken meat rolls and patties. The combination of two different sources of dietary fiber has been used viz. rice bran and psyllium husk. Three different levels of rice bran and psyllium husk viz. 10% rice bran and 2% psyllium husk, 10% rice bran and 4% psyllium husk and 10% rice bran and 6% psyllium husk were tried. The sensory char...

Soil stabilization has become a major issue in construction engineering and the researches regarding the effectiveness of using industrial wastes are rapidly increasing. The present experimental work briefly describes the suitability of the locally available Rice Husk Ash (RHA) to be used in the local construction industry in a way to minimize the amount of waste to be disposed to the environme...

rice husk is as an organic solid waste material that has high adsorbing capacity in removal of heavy metal ions from wastewater, and can be very effective in treating industrial aqueous solutions that are important sources of water and soil pollution. in this study, the removal of zn(ii) and cr(vi) ions from aqueous solutions using rice husk was investigated. the investigated parameters include...
