Aflatoxins in food and feed with prominent toxic effects have jeopardized public health for decades. This investigation intends to explore synthesized SDS-modified chitosan as new generation of binder for removal of aflatoxin using a straightforward ionic cross-linking approach. The primary objective of this technique was to enhance affinity and adsorption capability of SDSCS towards aflatoxins.

Article Synopsis
- * Two doses of the agent (30 mg and 90 mg per cow per day) were evaluated over different incubation periods (1, 4, and 24 hours), with analytical methods showing significant reductions in mycotoxin levels.
- * Results indicated that the lower dose (30 mg) effectively bound several toxins, suggesting it may be sufficient for protective effects, although complexities in toxin interactions within the rumen complicate definitive conclusions. *

This research investigates the efficacy of sp. biomass as an effective adsorbent for the removal of AFB and OTA from aqueous solutions. Several factors, including contact time, adsorbent dosage, pH level, and initial mycotoxin concentration, were analyzed to evaluate their impact on adsorption efficacy.

A magnetic nanoadsorbent was prepared via a novel one-pot magnetization method by employing natural carboxymethyl cellulose (CMC), polyaniline (PANI) nanotube, and graphene oxide (GO) for the effective adsorption of aflatoxins B1 (AFB1) and B2 (AFB2) from rice samples. This synthesized adsorbent combines the multifunction of CMC, PANI, and GO and shows improved extraction performance. FT-IR, XRD, FE-SEM, VSM, and TGA analyses were used to investigate the successful synthesis of the nanocomposite.
