Adsorbent properties and aqueous characteristics are very important parameters in the removal efficiency (RE) of environmental pollutants. The main goal of this study was to investigate the effects of pH, particle size and porosity of raw rice husk and its silica on removing lead and hexavalent chromium (Cr+6) from aqueous solution. The raw rice husk was collected from north of Iran and the ric...

Abstract Purpose Rice is a staple crop worldwide and silicon (Si) hyperaccumulator with Si levels reaching 5–10% of its mass; this can result in desilication Si-deficiency if plant residues are not managed correctly. also uniquely subject to arsenic (As) cadmium (Cd) contamination depending on soil conditions. Our goal quantify the effects rice husk (a Si-rich milling byproduct) amendments diff...

Background: There are some reports on the positive effectsof dietary insoluble fiber on the performance of broilers. Objectives: This study was carried out to determine theeffect of inclusion rate and particle size of rice husk in the diet of broilerson the ileal and cecal bacteria populations and small intestine morphology. Methods: The experimental diets  consisted of a control husk-free diet...

in this study, rice husk and sodium silicate solution were used to produce particleboards. sodium silicate was used as bonding aid by 25, 20, 15, 10, 5 and zero percent (based on rice husk dry weight). to modify the mechanism of bondability, one percent of 4,4’-diphenylmethane diisocyanate (mdi) was added for every five percent less sodium silicate solution. the effect of diisocyanate on bondab...

The research is potentially attractive for converting silica rich biomass into useful materials. Silica containing specimens prepared by the thermal method and deposition from rice production waste (straw and husk) were evaluated for their ability to remove different strains of microorganisms from the water. The strains of microorganisms with different cell shape and size were chosen for invest...

This study was aimed to the examination of the effect of tillage row spacing and bush spacing on the performance and components of Phaseou vulgaris var. (line: cos16). The investigation was conducted as cut terraces and in terms of complete random blocks in three replicates at Brujerd Agricultural Research and Natural Resources in the agricultural year 2009-2010. Here, the main terraces with th...

Good seed growth is a factor in the success of oil palm cultivation due to genetic pre-nursery factors field, so that provision nutrients initial plays an important role determining overall appearance seedlings during its growing period. This study aims determine effect by applying Uera fertilizer and rice husk charcoal organic field. The experiment was carried out from October 2020 May 2021 ex...

Mini-cutting technique of tree species is an effective method maintaining desirable features plant matrices and uniformity. The objective the present research was to determine substrate concentration indolebutyric acid (IBA) more suitable for mini-cuttings Carya illinoinensis rooting. experiment carried out in a greenhouse with mist, from February May 2018. used experimental design blocks facto...

In this study, carbonized apricot stones and rice husk were utilized as feedstock for the synthesis of CuO-loaded sorbents removal carbon dioxide (CO2) from gas mixtures. The specific surface area increased with increasing carbonization temperature, resulting in a porous structure enhanced sorption capacity. presence pores development porosity confirmed by SEM images. CuO nanoparticles well-dis...

Urea fertilizer as a nitrogen source is used widely and globally. However, N loss through ammonia volatilization from applied urea has become major drawback to agriculture. A pot experiment was conducted determine the effect of rice straw biochar on (1) total N, soil exchangeable NH4+, available NO3− (2) uptake P, K in plants. The treatments evaluated were: (S: Soil only, U: + 175 kg ha−1 urea,...
