Preparation of sodium silicate from bagasse fly ash was performed as per the modified methods of Ruengrung et al 11 18.648 g of bagasse fly ash (74.23% SiO 2 ) was mixed with 22.601 g of sodium carbonate (Na 2 CO 3 , Kemaus, NSW, Australia) for 30 min. After calcining at 850 °C for 1 h, using a heating rate of 10 °C/min, a blue solid product was obtained.…”

“…The use of zeolites and hydrated sodium calcium aluminosilicate may, however, result in the release of toxic components, including heavy metals or dioxins . On the other hand, activated carbon, which is one of the most popular adsorbents due to its low cost, possesses excessively fine pore characteristics that may limit the transport of the larger molecules of AFB1 into the pores . Selection of a suitable adsorbent material remains a challenge for AFB1.…”

Effect of the Structure of Highly Porous Silica Extracted from Sugarcane Bagasse Fly Ash on Aflatoxin B1 Adsorption

et al. 2023

Sugarcane bagasse fly ash is industrial waste produced by incinerating biomass to generate power and steam. The fly ash contains SiO2 and Al2O3, which can be used to prepare aluminosilicate. This latter material exhibits high potential as an adsorbent in various applications, including the livestock industry where issues related to contamination of aflatoxins in animal feeds need to be addressed; addition of adsorbents can help decrease the concentration of aflatoxins during feed digestion. In this study, the effect of the structure of silica prepared from sugarcane bagasse fly ash on physicochemical properties and aflatoxin B1 (AFB1) adsorption capability compared with that of bentonite was investigated. BPS-5, Xerogel-5, MCM-41, and SBA-15 mesoporous silica supports were synthesized using sodium silicate hydrate (Na2SiO3) from sugarcane bagasse fly ash as a silica source. BPS-5, Xerogel-5, MCM-41, and SBA-15 exhibited amorphous structures, while sodium silicate possessed a crystalline structure. BPS-5 possessed larger pore size, pore volume, and pore size distribution with a bimodal mesoporous structure, while Xerogel-5 exhibited lower pore size and pore size distribution with a unimodal mesoporous structure. BPS-5 with a negatively charged surface exhibited the highest AFB1 adsorption capability compared with other porous silica. However, the AFB1 adsorption capability of bentonite was superior to those of all porous silica. Sufficient pore diameter with high total pore volume as well as high intensity of acid sites and negative charge on the surface of the adsorbent is required to increase AFB1 adsorption in the in vitro gastrointestinal tract of animals.
