Abstract
The invention discloses an amylase auxiliary laccase modified millet straw adsorption material as well as a preparation method and application thereof, and belongs to the technical field of adsorbent materials. The preparation method of the amylase and auxiliary laccase modified millet straw adsorption material comprises the following steps: soaking cooked millet straw in an amylase solution, taking out the millet straw, soaking the millet straw in a laccase solution, and then performing enzyme deactivation, cleaning and drying to obtain the amylase and auxiliary laccase modified millet straw adsorption material. The used raw material, namely the millet straw, is used as agricultural waste, is rich in resources and active groups such as cellulose and lignin, and has good adsorption potential. According to the invention, the millet straw is used as a raw material, a bio-adsorbent for efficiently adsorbing nicotine is developed through technologies such as modification, and the millet straw adsorption material with high adsorption capacity is prepared through an optimized preparation process, so that the millet straw adsorption material is beneficial to guaranteeing human health, and the millet straw agricultural and forestry wastes are utilized in a low-energy-consumption and environment-friendly and efficient manner.
