The synthesis of nanoparticles silica oxide from rice husk, sugar cane bagasse and coffee husk, by employing vermicompost with annelids (Eisenia foetida) is reported. The product (humus) is calcinated and extracted to recover the crystalline nanoparticles. X-ray diffraction (XRD), transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HRTEM) and dynamic light ...
abstract- as the world's population has grown and become more urban and affluent, waste production has raised drastically. wastewater reuse has been identified as a way to alleviate water scarcity and improve crop productivity and environmental sustainability. to address the issue, a soil column experiment was carried out in a 3 × 3 factorial randomized block design including three treatments o...
This study evaluates the adsorption of bisphenol-A (BPA) from aqueous solutions using nanosilicaobtained from rice husk. Nanosilica (79 nm) was extracted from acid and thermal treated rice huskwaste. The rice husk nanosilica (RHS) was fully characterized through X-Ray DiffractionSpectroscopy (XRD), Scanning Electron Microscopy (SEM), X-Ray Fluorescence Spectroscopy(XRF) and Fourier Transmittanc...
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...
Present study dealt the removal of Cr(VI) in a tannery industry wastewater using rice husk silica powder as an adsorbent.The experimental investigations have been carried out by using rice husk silica powder for different adsorption dosage, different contact time and different pH against the initial Cr(VI) concentration of 292 mg/L. The maximum percentage removal of Cr(VI) in a tannery industri...
ADEROLU, Ademola Zaid, Eustace. A. IYAYI and Abiodun A. ONILUDE, 2007. Changes in nutritional value of rice husk during Trichoderma viride degradation. Bulg. J. Agric. Sci., 13: 583-589 Possible improvement in nutritional status of rice husk using Trichoderma viride a fungus was investigated over a period of 40 days. Proximate composition was significantly (P<0.05) improved with microbial treat...
This paper assesses the feasibility of two industrial wastes, fly ash (FA) and rice husk ash (RHA), as raw materials for the production of geopolymeric pastes. Three typologies of samples were thus produced: (i) halloysite activated with potassium hydroxide and nanosilica, used as the reference sample (HL-S); (ii) halloysite activated with rice husk ash dissolved into KOH solution (HL-R); (iii)...
The need to improve the access to safe water is generally recognized for the benefit of public health in developing countries. This study's objective was to identify critical parameters which are essential for improving the performance of ceramic pot filters (CPFs) as a point-of-use water treatment system. Defining critical production parameters was also relevant to confirm that CPFs with high-...
Ionic liquids have been employed to deconstruct and fractionate lignocellulosic biomasses because of their capacity to dissolve cellulose. However, there is limited literature reporting the use of ionic liquids in biomass saccharification, which mostly involves the addition of acid or water that conceals the true action of ionic liquid in saccharification. This article assesses the performance ...
This study aimed to compare the inactivation rate and the mechanisms of pathogenic bacteria in three matrixes (sawdust, rice husk and charcoal) during the composting process. The inactivation rate was evaluated with Escherichia coli strain and the damaged parts and/or functions were evaluated with three different media. Normalized inactivation rate constant in three media and from three matrixe...
