摘　　要：Studies of carbon nanomaterials(CNM)synthesized from lignocellulosic biomass,and natural and technical lignins were carried out.For the first time,we suggested using stems of Sosnovsky hogweed,one of the most aggressive and poisonous invasive plant species,to produce CNM.The influence of the choice of raw materials and synthesis conditions on the sorption and surface-porous characteristics of the samples was evaluated.The main regularities of adsorption processes from aqueous media with a low concentration(0.625μg/ml)of uranium were established.We found that strong retention of uranium characterizes carbonized biopolymers(CBP)samples,a significant amount of which(67-70%)is not desorbed either by water or aqueous solutions of CH3COONH4 and HCI(1 M).In addition,we found out that the carbon nanomaterials we synthesized can adsorb mycotoxin T-2.The obtained results indicated a high innovative potential of CNM.
