Abstract
A carbon fixation material for adsorbing heavy metals in soil and a preparation method thereof are provided. The carbon fixation material includes modified biochar, calcium silicate, aluminum sulfate, hydroxymethyl cellulose and urea. The modified biochar is prepared by preparing biochar from agricultural and forestry waste, and modifying the biochar with ferric chloride and a mercapto silane coupling agent. The carbon fixation material has excellent carbon fixation capacity, the biochar is prepared by processing agricultural and forestry waste, the material source is green and environmentally friendly, can reduce environmental pollution. After modified by ferric chloride and mercapto silane coupling agent, the biochar has excellent adsorption amount and adsorption capacity for heavy metal ions and has strong retention capacity after adsorption, the modified biochar can be widely used in soil carbon fixation and heavy metal pollution treatment.
