| titleOfInvention | Preparation method and application of iron-enriched biological carbon of cattail roots |
| abstract | The invention provides a preparation method of iron-enriched biochar from typha root, which comprises the steps of screening mature cattail with strong growth, cleaning, adding into an incubator, self-cleaning for two weeks in distilled water and Hoagland's nutrient solution, and adding FeSO 4 ·7H 2 Changing the culture solution for 1-2 months by using O solution, and adding deionized water for comparison; cutting the roots of the plant with the iron element added to the cattail and the blank control group of deionized water, drying until no moisture exists, pumping air in a crucible under a closed condition, introducing nitrogen until the pressure inside and outside the tube is balanced, adjusting the flow rate of the nitrogen to be 15-25mL/min, and sintering at the temperature of 500-900 ℃ to obtain biochar; grinding the biochar, pouring 3-6mol/L NaOH solution, stirring at 70-85 ℃ for 1-3h, filtering, washing with water, standing, pouring out scum, and drying to obtain the copper-enriched biochar from ciliate desert-grass. The technical scheme of the invention applies the prepared cattail root iron-enriched biochar to remove methylene blue. |
