A comparative study of sorbents based on several natural biopolymers and their carbonized products - few-layer graphenes obtained under the self-propagating high-temperature synthesis process - was conducted using the example of mycotoxin T-2 sorption. The studies show that the efficiency of mycotoxin T-2 sorption by few-layer graphenes in all indicators, including the irreversible sorption indicator, significantly exceeds similar characteristics for the original biopolymers (sulfate lignin, microcellulose, pine bark, birch lignin). The adsorbents were also studied using the low-temperature nitrogen adsorption method. Keywords: mycotoxin sorption, mycotoxin T-2, lignin, few-layer graphene.
