  • METHOD OF FABRICATING A COMPOSITE MEMBRANE CONTAINING A METAL ION ADSORBENT
    Publication number: 20150034860
    Abstract: A method of fabricating a composite membranes containing a metal ion adsorbent, the method comprising the following steps: mixing a metal ion adsorbent powder and a solvent to form a mixture, wherein the solvent is capable of dissolving cellulose; mixing the mixture and cellulose to form a gel blend; removing the solvent from the gel blend, and drying the gel blend to obtain a composite membrane containing a metal ion adsorbent. By means of mixing metal ion adsorbent and cellulose by phase inversion to obtain the composite membrane containing a metal ion adsorbent, the composite membrane containing a metal ion adsorbent can remove heavy metal ions from industrial wastewater.
