titleOfInvention | Preparation method of multifunctional composite hydrogel |
abstract | The invention discloses a preparation method of multifunctional composite hydrogel, belonging to the field of high polymer materials. The product of the invention is characterized in that the product not only can effectively carry out qualitative detection on the heavy metal ions in the water, but also can absorb the heavy metal ions in the water. The adsorption removal rate of the product of the invention on low-concentration heavy metal ions such as nickel, chromium, lead, mercury and the like in wastewater reaches more than 90%. The preparation of the product of the invention does not need special equipment, is easy to realize industrialization and has low product cost. After the composite gel product adsorbs heavy metal ions, the adsorbed heavy metal ions can be efficiently recovered by cleaning through a cleaning solution, more than 95% of the adsorbed heavy metal ions can be washed away at one time, and the gel can be reused. |
