Abstract
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 (0.625 μg/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.
期刊介绍：
Carbon Resources Conversion (CRC) publishes fundamental studies and industrial developments regarding relevant technologies aiming for the clean, efficient, value-added, and low-carbon utilization of carbon-containing resources as fuel for energy and as feedstock for materials or chemicals from, for example, fossil fuels, biomass, syngas, CO2, hydrocarbons, and organic wastes via physical, thermal, chemical, biological, and other technical methods. CRC also publishes scientific and engineering studies on resource characterization and pretreatment, carbon material innovation and production, clean technologies related to carbon resource conversion and utilization, and various process-supporting technologies, including on-line or off-line measurement and monitoring, modeling, simulations focused on safe and efficient process operation and control, and process and equipment optimization.
