The present invention relates to the technology of material surface modification and the preparation adsorption new material, which involves the preparation of CQDs and the application of CQDs on modifying water purification function material. Firstly, the CQDs with rich functional groups and specific graphene structure has been prepared based on the low-cost biomass. Then, modified the traditional adsorbent by prepared CQDs under the in situ synthesis process. Secondly, synthesis the CQDs basic on the organic waste-water under low-temperature hydrothermal treatment process. Then, prepared the CQDs modified water purification material by collecting the CQDs under the flocculation process. This invention can be used in the widely used in the field of modification and preparation of functional materials, because of it not only gives a new method to synthesis low-cost and high performance water purification material, but also provide a new idea to treat high toxicity and refractory organic waste-water. |
