Abstract:
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.

Claim (Index 1):
A preparation method of a carbon quantum dot, comprising steps of:\n 1) washing raw biomass material by deionized water and then further cutting the raw biomass material into small pieces and drying the raw biomass material at 60\u00b0 C. for 24 hours; preparing 1-100% solid-to-liquid ratio of biomass/water mixed suspension; 2) heating the mixed suspension at 100-200\u00b0 C. for 2-10 hours to obtain biomass base CQDs (Carbon Quantum Dots) solution with hydroxyl group and carbonyl groups; and 3) filtering and drying the biomass base CQDs solution to get biomass base carbon quantum dots powder, so as to protect fine structure and surface functional groups of the biomass base carbon quantum dots.
