摘要： The present disclosure provides a recycling method of amphiphilic surface-active pollutants in water, comprising: performing a polymerization reaction by illumination treatment on the amphiphilic surface-active pollutants in water to form a polymerization product; performing self-assembly on the polymerization product for aggregation to form a fluorescent material, and performing separation to obtain a recycled product. Through treatment of the amphiphilic surface-active pollutants by illumination, the present disclosure can realize the recycled utilization of the amphiphilic pollutants in the wastewater by one step of reaction, so that the amphiphilic surface-active pollutants can be converted into usable fluorescent materials, and the biological toxicity is greatly reduced. The obtained fluorescent material can be further used in the fields such as biological imaging as a recycled product, realizes detoxification of the pollutants and efficient conversion of organic carbon resources at the same time, provides a novel strategy for wastewater treatment and resource conversion, and achieves a win-win situation for economic benefits and environmental friendliness in the field of amphipathic organic pollution treatment and has a good application prospect.

摘要： The present disclosure relates to a treatment method of wastewater containing heterocyclic organics comprising the following steps: (1) adding a persulfate to the wastewater containing heterocyclic organics in a reaction vessel; (2) heating the reaction vessel to a reaction temperature in an inert atmosphere, then introducing an oxygen-containing gas until a reaction pressure is reached for reaction, and after the reaction is completed, cooling and filtering the reaction resultant to obtain a filtrate as a treated effluent and a filter residue; no catalyst is added to the reaction system. The treatment method provided by the present disclosure not only can significantly reduce the treatment temperature of the conventional wet oxidation, but also can control the amount of generated spherical polymer and the removal efficiency of organic pollutants by control of reaction conditions. Wastewater purification and organics recovery and reuse are achieved at the same time.

摘要： The present invention provides carbon quantum dots, preparation method and uses thereof. The preparation method of the carbon quantum dots comprises the following steps: (1) preparing a dispersion of carbon based material; (2) mixing a solution of halogenated quinone with the dispersion of carbon based material and preparing a dispersion of carbon based-halogenated quinone composite material by halogenated quinone grafting method; (3) adding a solution of H2O2 to the dispersion of carbon based-halogenated quinone composite material and carrying out reaction thereof, obtaining reaction products; (4) carrying out solid-liquid separation to the reaction products, with the resulting filtrate continuing to react, thus obtaining a dispersion of carbon quantum dots. This method adopts metal-free catalytic oxidation, the process of which is safe, convenient and low-cost, and is performed under a mild reaction condition without adding additional substances which are difficult to be separated. The obtained quantum dots have a good dispersibility and can be easily separated, also can achieve pollution treatment using pollutants. In addition, the prepared carbon quantum dots have a broad application prospect in the fields of organic pollutant degradation, electrochemical sensors, super capacitors, luminescent materials and photoelectric devices, etc.
