Optimization of toxic biological compound adsorption from aqueous solution onto Silicon and Silicon carbide...

The subject of this paper is removal of Aflatoxin B₁ as toxic biological compound adsorption onto Silicon (Si) and Silicon carbide (SiC) nanoparticles in aqueous matrices using Response surface methodology. The surface frame of Si and SiC nanoparticles were comminuted by XRD, TEM, SEM, and BET. Experiments were steered well-found by Box-Behnken plan (BBD). Experiments of batch method were performed to prognosticate the reaction equilibrium of Aflatoxin B₁ removal. The response surface methodological approach was used. In the agreeable perusal, effect of adsorbent dosage, temperature and pH on the Aflatoxin B₁ adsorption from aqueous matrices using Si and SiC nanoparticles has been investigated. The interplay of the changeables and their implication was studied using the analysis of variance. The optimum adsorbent dosage, pH, and temperature were obtained to be 0.04g, 9.0 and 278K, respectively and adsorption of Aflatoxin B₁ was 42.50 and 46.10mg/g for Si and SiC nanoparticles, respectively.
