Preparation of hierarchically biomass from waste for regeneration of extracted organic phases
The discharge of discarded organic phases often carries the risk of polluting the environment. The recycling and utilization of organic phases can reduce the negative impact on the environment and the consumption of natural resources. This manuscript reports a method for preparing biomass porous carbon using discarded mungbean pods and applying it to capacitive deionization (CDI) technology for organic phase regeneration. During the preparation process, porous carbon was prepared using potassium carbonate as an activator, NaCl/KCl mixed salt as a template and flux, and dopamine as a nitrogen source. The biomass-graded porous carbon prepared has a high specific surface area (2862.36 m2 g−1), rich pore structure, and good electrochemical performance (specific capacitance of 480.5 F g−1 at a current density of 1A g−1), making it suitable for ion adsorption and desorption processes in CDI technology. The CDI regeneration extraction organic phase experiment verified that the extraction ability of the regenerated extracted organic phase of the material in the extraction experiment can reach 99.6% of that of the fresh extractant. The results indicate that biomass-graded porous carbon has high ion adsorption capacity and good regeneration performance, which can achieve the recycling of organic phase.
