Abstract:

Pesticide is an important input in agricultural production. Due to the restricting elements such as pesticide improper use, pesticide resistance and environmental factors, the effective utilization rate of pesticide is low. Pesticide pollution of soil can lead to soil dysfunction, and the exposure of pesticide may cause acute, chronic and long-term harm to human health. As a new material, biochar can be used to fix/degrade pollutants and minimize the risk of soil pollution with its high aromatic character, excellent absorbability and environmental friendliness. In this paper, the characteristics and formation mechanism of biochar, its adsorption mechanism of pesticides and the pathway of functionalization are briefly discussed by summarizing the research results at home and abroad.

Key words: biochar, pesticide, environment, modification, adsorption
