Rice consumption is a major dietary source of Cd and poses potential threat to human health. The aims this study were examine the influence Fe application on yield components, dynamics in pore water, translocation factors, daily intake, estimation health risks. A pot experiment was performed under glasshouse conditions where rice cultivars (Langi Quest) cultivated two dissimilar soils different...

Improvement of Chemical Properties Ex-Gold Mine Land Through Application Rice Husk Biochar and Chicken Manure. Ex-gold mining land that have been degraded so soil fertility is very low. Mining with an open system causes increase in the oxidation sulfuric minerals which reduces nutrient levels, it necessary to make efforts nutrients through addition rice husk biochar manure. The purpose study wa...

Pesticide is a pollution problem in agriculture. The usage of ZnCr2O4/CNS and H2O2 as additive liquid fertilizer has potency for catalytic pesticide degradation. Colloid condition needed easy spraying. Rice husk sawdust were used carbon precursor ZnCl2 activator. biomass–ZnCl2 mixtures pyrolyzed using microwave (400–800 W, 50 min). products dispersed water by blending then evaporated to obtain ...

Indian spinach (Basella alba) originates from Asia but is now grown in most tropical regions as a leafy vegetable crop. It is usually cooked but can also be used raw in salads. Rice hulls (or rice husks) are the hard protecting coverings of grains of rice. In addition to protecting rice during the growing season, rice hulls can be put to use as building material, fertilizer, insulation material...

a mild, efficient and fast method for the trimethylsilyl (tms), tetrahydropyranyl (thp) and methoxymethyl (mom) protection of alcohols and phenols in the presence of sulfonated rice husk ash (rha-so3h) is reported. all reactions were performed at room temperature in high to excellent yields. all the products are separated and compared with authentic samples and/ or identified using different ty...

background and purpose: recently, release of pollutants such as heavy metal ions to the environment becomes one of the most important problems for soil and water. the present study was conducted to introduce modified rice husk (rh) as a new low-cost adsorbent. materials and methods: in this study, tartaric acid modified rh (tarh), was used as an adsorbent for removal of ni(ii) and cd(ii) from w...

In the present study a strain of Bacillus subtilis-BS05 was grown in submerged fermentation of agricultural wastes for xylanolytic activity. Various agricultural wastes such as sugarcane bagasse, wheat straw, rice husk, soybean meal, corn cobs and wheat bran were evaluated for xylanolytic acitivity using different media (M-I, M-II, M-III & M-IV). Among all these tested substrates maximum xylano...

Spherical and needle-like cobalt nanoparticles incorporated on rice husk silica was synthesized by a simple, rapid and eco-friendly sol-gel route at room temperature. This was achieved by direct mixing of 20 wt.% Co with sodium silicate from rice husk under ambient conditions to form RH-20Co. The cobalt was found to be isomorphously substituted in the silica matrix. A good dispersion of cobalt ...
