| titleOfInvention | Preparation method for zinc ion adsorption material |
| abstract | The invention belongs to the technical field of water treatment, and relates to a preparation method for a zinc ion adsorption material. According to the invention, alternanthera philoxeroides is modified, and the particular technology comprises the steps of cleaning, grinding, modification through a mixed solution of propenoic acid and nitrilotriacetic acid trisodium salt, and treatment through dimethylamine. The adsorption material for the zinc ion, prepared through the invention, has the following advantages: (1) the adsorptive selectivity in regard to the zinc ion is strong; (2) the prepared adsorption material for the zinc ion is organic matter and is degradable; (3) the alternanthera philoxeroides is rich in organic acid, phenolic compounds, coumarin, and saccharides, and the components are fully utilized to adsorb the zinc ion, so that the adsorption amount of the zinc ion is increased to 46 mg/g, that is, one gram of adsorption material can adsorb 46 mg zinc ion, and the adsorbed amount is 20 times as that adsorbed by activated carbon. The zinc ion adsorption material can be applied to zinc-containing waste water treatment for an electroplate plant, and the market prospect is wide. |
