| titleOfInvention | Preparation method of hybrid film adsorbent for removing heavy metal ions in water |
| abstract | The invention discloses a preparation method of a hybrid film adsorbent for removing heavy metal ions in water. The preparation method is characterized in that: in an inert atmosphere or in air, at 0 ~ 150 DEG C, a crosslinking agent as a reactant is added into a polyvinyl alcohol water solution with the mass percent concentration of 0.1% ~ 10%, and the mass ratio of polyvinyl alcohol: crosslinking agent is 1:0.01 ~ 0.1, under the effects of a dilute acid with the molar concentration of 0.001-0.1M, a cross-linking reaction is performed to obtain a solution, a silane coupling agent is added into the solution, and the mass ratio of polyvinyl alcohol (PVA): silane coupling agent is 1:0.1-1.0, a sol-gel reaction is performed to obtain a product, the product is statically stood for defoaming, and then is coated with a film to obtain a film sheet, and the obtained film sheet is dried to obtain the hybrid film adsorbent for removing the heavy metal ions in the water. The hybrid film adsorbent prepared by the preparation method is good in film forming performance, has strong adsorption selectivity to Pb<2+>, Cu<2+> and other heavy metal ions in the water, and can be used for adsorption and removal of the heavy metal ions in the water. |
