Abstract: |
The present invention relates to a preparation method of ammoniated mycelium adsorbent, in particular, it provides a preparation method of mycelium adsorbent whose surface has positive charge. Said invention can make macromolecular polymer containing lots of amino-group be grafted on the mycelium surface by means of two-step simple chemical reaction so as to greatly raise the density of adsorbent surface amino-groups. Its preparation method includes the following steps: using mycelium as raw material, firstly, adding mycelium into an organic solvent of cross-linking agent and making reaction for 8-24h, the volume weight ratio of cross-linking agent and mycelium is 0.5-4ml/g, then adding mycelium into an organic solvent containing amino-group macromolecule, the weight volume ratio of amino-group macromolecule and organic solvent is 5-20g/100ml, heating to 80-100deg.C and making reaction for 10-24h so as to obtain the invented ammoniated mycelium adsorbent. |
