Abstract
A preparation method for a nanopore starch-based adsorbent. The method mainly comprises: constructing a large number of lamellar crystals on surfaces of starch granules, and inducing the formation of a nano-scale pore channel structure by means of the lamellar crystals. A large number of control tests have proved that the flaky crystals have direct influence on the formation of the nano-scale pore channel structure. The construction of a pore channel structure in a starch matrix material greatly increases the specific surface area, and improves the adsorption properties. In addition, the method is beneficial to the introduction of functional particles (magnetic particles), and avoids the problem of pore channel blockage due to first forming pores and then introducing functional particles.
