“…Previous reports have shown the potential of raw rice husk and rice husk ash as adsorbent materials for metals in aqueous media [18][19][20]; however, chemical and physical changes on the material are required to optimize their adsorbent capacity [21]. This study was aimed to evaluate the Cd (II) adsorption capacity onto different adsorbent materials obtained from rice husk chemically and thermally treated (not necessarily as ash).…”

Chemically and thermally treated rice husks were evaluated as a potential decontaminant of toxic Cd (II) in aqueous media. Rice husk (RH), a by-product from rice milling, was chemically treated with HCl and NaOH. Then, thermal treatments to 300, 500, and 700∘ C were applied. The chemical composition and morphological characteristics of RH were evaluated by different techniques. The specific surface area analysis of RH samples by BET nitrogen adsorption method provided specific surface areas ranging from 6 to 14 m 2 /g. SEM, FTIR, and EDX analyses of RH were carried out to determine the surface morphology, functional groups involved in metal binding mechanism, and C/O and C/Si ratios, respectively. The maximum Cd (II) adsorption capacity was 28.27 mg/g at an optimum pH, 6.0. The kinetic studies revealed that adsorption process followed the pseudo-second-order kinetic model.

“…Soltani et al [27] spotlighted the applications of RH in different fields and discussed the uses of RH silica to synthesize some advanced non-oxide ceramics, silicon, and nano SiO 2 , and their different fabrication processes as well as the process parameters. Liu et al [28] elaborated the pozzolanic and adsorbent characteristics of RHA in a study. Shen (China) [29] reviewed current growth in the preparation of RH silica and its applications in environmental and energy functional materials.…”

Use of waste or by-products from different industries and the agricultural sector has received increasing attention in the scientific, technology, ecological, economic and social spheres in recent years. Rice husk (RH) is a by-product of rice milling and rice husk ash (RHA) is generated by combustion in a separate boiler. Both RH and RHA are abundantly accessible in rice growing countries such as China, India, Brazil, the USA, and Southeast Asia. RH has therefore been recycled by burning it for energy production. This generates RHA, which contains a huge quantity (85-95%) of amorphous silica. Over the past two decades, RHA has been used extensively in numerous fields for manufacturing of different silicates, zeolites, catalysts, nanocomposite, cement, lightweight construction materials, insulators, and adsorbents. This paper presents a comprehensive overview on the processing of nano-silica from RH/RHA. It tries at the same time, to present a critical review of the application of RHA as an ingredient for the production of various ceramic materials, e.g. refractory, glass, whiteware, oxide and non-oxide ceramics, silica aerogel and SiO 2 /C composites. In summary, amorphous silica derived from RHA or RH provides a potential alternative to conventional silica sources (e.g. quartz) for the manufacture of value-added ceramics for practical applications.

“…The other compounds for the rice husk ask low, it is show that after burning of rice husk, all impurities remove. Liu et al, 2013 [9] has mentioned that removing organic matter occured only heat at moderate temperatures to avoid the fusion of the SiO 2 product. In biological system, the six metals common come such as Na, Mg, Al, K, Ca, and Fe, and also Si, were detected simultaneously with the mass spectrometer.…”

The current development of the packaging industry is increasing as well as the dependence of non-renewable oil-based materials encouraging researchers to look for alternative polymeric strengthening materials from biomass. Especially used from agricultural waste because it is cheap and widely available in nature and it can be renewed. In this study, agriculture waste used were rice husk and rice husks ash that prepared as organic nanofillers for the development of polymer nanocomposites. XRF analysis showed that rice husk ash has the highest silica (SiO2) content of 89. 835%, while rice husk has SiO2 contents of 82.540%. From XRD analysis on 2 theta there is a crystalline silica region at 22° and this analysis shows the sample is amorphous. FTIR analysis showed Si-H at peak 2339 cm−1 in rice husk and 2129 cm−1 for rice husk ash.
