Abstract: In this paper, using popcorn as raw material, through the combination of low temperature carbonization, activation, high temperature carbonization and chemical modification, ordinary popcorn was successfully transformed into carbon material with high specific surface area and porous structure, showing excellent adsorption properties. Through the experiment, the experimental results were analyzed and discussed, and the optimum process conditions were determined as follows: low temperature carbonization temperature 300℃, carbonization time 3h; The concentration of activator KOH was 1.5mol/L. High temperature carbonization temperature 900℃, carbonization time 3h. Under the experimental conditions, the removal rate of modified popcorn porous carbon to acid lake blue A dye can reach 93%, and the removal effect is remarkable.This study not only provides an economical and efficient strategy for waste resource utilization, but also establishes the structure-activity relationship of food waste-derived adsorbents, offering new insights for industrial wastewater treatment.
