This study contains a lab-scale investigation into the feasibility of applying an adsorption technique to treat wastewater polluted with lead metal simulated that exhaust from battery manufactory. Rice husks have been prepared for use in three forms; natural rice without any activation, activated carbon pretreated Sulfuric acid H2SO4, and other Potassium hydroxide KOH. Activated using KOH provi...

Experiments were conducted to determine the effects that different methods for the preparation of modern plant samples have on the resulting phytoliths using rice husks (Oryza sp.). The methods that are commonly used in phytolith extraction include (1) dry ashing, (2) acid extraction (3) a combination of both techniques. The results showed that processing methods have an impact on the morpholog...

Textile effluents are major industrial polluters because of high color content, about 15% unfixed dyes and salts. The present paper is aimed to investigate and develop cheap adsorption methods for color removal from wastewater using waste materials activated carbon and activated rice husk-as adsorbents. The method was employed for the removal of Safranin-T and the influence of various factors s...

Tiiiv interesting letter from Dr. Rajandra Prasad on the above subject in the May number of the Indian Mcdical Gazette was found by nic a very opportune one, as similar cases occurred in Bulsar. On 16th June, 1929, in the afternoon I was sent for to render artificial respiration to 3 patients. The history was as follows:?A rice mill had a disused well in its compound, which for some reason or o...

This paper presents the results of an experimental study on evaluation ofphysical and thermal properties cementitious composites based plant biomass (rice husks palm tree fibers). Composites produced are cement mortars with total replacement sand by aggregates rice (B) or fibers (F). Three content (D1, D2 D3) two granulometries (coarse mixture fine mixture) were used for manufacturing studied s...

Heavy metals are widely used in textile industries and significant losses occur during the manufacture and processing of textiles, and these lost heavy metals are discharged in the effluent. Adsorption of heavy metals is a new technology for treatment of wastewater containing different types of selected heavy metals. In this study, adsorbents Carbonized Rice Husk (CRH) and Activated Rice Husk (...

This review contains the main research directions, which are directly aimed at converting materials based on rice husks particularly, for their role medicine and biotechnology. Especially in developing countries, more than 95% of produced. Although numerous studies have been conducted production various from husks, existing scientific information is still widely scattered literature. Therefore,...

The aim of the present study was to evaluate the effect of cocoa husks feeding on liver composition of the Italian heavy pig. Cocoa husks are by-products derived from chocolate production and have a high content of proteins, lipids, and NDF. Cocoa husks are also rich in antioxidants, polyphenols in particular. Eight finishing pigs were divided into 2 groups: control group fed a traditional diet...

The contamination of paddy soils by arsenic (As) is a serious problem in rice production areas across the world. This study investigates the effect selenium (Se) has on the formation of iron plaques on the outside of rice roots and the accumulation of As in rice plants. A soil combined sand pot experiment having four concentrations of Se (0, 1, 5 and 10 mg kg -1 ) and two concentrations of As (...
