Research progress and application prospect of humic acid grafted copolymer
This paper reviews the development status of graft copolymers and the research progress of hu-mic acid copolymers.Humic acid has a variety of oxygen-containing functional groups,such as carboxyl group,phenol hydroxyl group and other groups,and humic acid molecules have the abilities of redox,hy-drophilic,complex,adsorption,dispersion and easy graft copolymerization modification.Humic acid copol-ymers were introduced from different uses.Because of their low cost,green and safe characteristics,they have broad application prospects in industry,agriculture,animal husbandry and medicine.
