| titleOfInvention | Modified biomass ash material and preparation method and application thereof |
| abstract | The invention discloses a preparation method of a modified biomass ash material, which comprises the following steps: (1) weighing biomass ash and potassium hydroxide with certain mass; (2) uniformly mixing biomass ash and potassium hydroxide, then transferring the mixture into a centrifuge tube, soaking, oscillating in water bath, taking out, and naturally cooling to room temperature; (3) centrifuging, filtering and separating the prepared centrifugal tube, washing with deionized water, and drying to obtain alkali modified biomass ash; wherein the mass ratio of the biomass ash to the potassium hydroxide is 4: 2-4: 5. Also discloses modified biomass ash prepared by the preparation method and application thereof in adsorbing and passivating heavy metals. The biomass ash is modified by potassium hydroxide, and the modified biomass ashThe biomass ash Si-O-Si number is increased compared with that before modification, and aluminosilicate (Ca (Al) 2 Si 2 O 8 ) The unique structure of the biomass ash greatly improves the adsorption effect of the biomass ash on heavy metals. |
