Abstract
A preparation method of a crop straw-based seawater desalinator and a product thereof, and the preparation process is as follows: (1) crushing crop straws, and screening the crushed crop straws through a mesh sieve to obtain straw powder; (2) calcining the straw powder at a high temperature under nitrogen protection to obtain biochar, and then putting the biochar into a ball mill for ball milling to obtain ball-milled biochar; (3) adding the straw powder into a sodium hydroxide solution for reaction, and centrifuging a reactant to obtain a viscous product; and (4) stirring the viscous product uniformly with the ball-milled biochar to obtain a mixture, pouring the mixture into a mold, and freezing and drying the mixture to obtain a seawater desalinator. The evaporator features high evaporation rate and the photothermal conversion efficiency, and the ion concentration of the water body after evaporation is greatly reduced.
