Abstract
A preparation method for a combined modified straw active particulate carbon adsorption material and use of same. The preparation method for the combined modified straw active particulate carbon adsorption material comprises the following steps: 1) mixing straw powders, distilled water, a binder and a composite mineral, then pelletizing same, and then placing same in a tube furnace for pyrolysis to prepare straw particulate carbon; 2) introducing an inert gas into a modification reagent, adjusting the pH value combined and 3) soaking the straw particulate carbon into the combined modification solution for 30 min, and performing cleaning and drying, so as to obtain a combined modified straw active particulate carbon adsorption material. The combined modified straw active particulate carbon has a good adsorption effect on phosphate group in low-pollution water.
