Preparation method of porous inorganic filling materials-fixed quinone compound

The invention discloses a preparation method of a porous inorganic filling materials-fixed quinone compound, belonging to the technical field of water treatment in environmental engineering. The method comprises the following steps of: selecting porous inorganic filling materials such as ceramsites, volcanics and the like; plating gamma-aluminum oxide on the surface of the materials; aminating, so that the surfaces of the porous inorganic filling materials contain a certain quantity of primary amidogen; putting the aminated materials into hydrochloric solution to have reaction for protecting the primary amidogen; and putting the reacted porous inorganic filling materials into sodium hydroxide solution, adding sulfonyl chloride group-containing anthraquinone compound which is dissolved in dichloromethane, and reacting for 6-10h under the room temperature to fix the water-soluble quinone compound. The quinone compound-containing macroporous polymer is applied to an anaerobic reactor to be capable of improving the biotransformation speed of an organic matter which is hardly degraded. The method covalently fixes the quinone compound on the macroporous polymer of a biologic carrier, so that the redox medium is easily contacted with the microbe, thereby overcoming the problem of the secondary pollution since the water-soluble quinone compound flows out with the water.

Novel method for analyzing tyrosinase activity using carbon quantum dots as fluorescence probes

The invention discloses a novel method for analyzing tyrosinase activity using carbon quantum dots as fluorescence probes, characterized in that when an assay system contains only tyrosinase or dopamine ,the fluorescence of the carbon quantum dots remains stable; and when the assay system contains tyrosinase and dopamine simultaneously, the tyrosinase catalyzes the oxidation of dopamine to producequinonoids, resulting in quenching of the fluorescence of the carbon quantum dots; based on which a fluorescence analysis method for detecting tyrosinase is established. The novel method for analyzing tyrosinase activity using carbon quantum dots as fluorescence probes has the advantages of being fast, sensitive and simple. Further, the quenching of the fluorescence of the carbon quantum dots hasa good linear correlation with the concentration of tyrosinase, and the detection limit is as low as 0.039 U / mL. Meanwhile, a recovery rate of tyrosinase in actual human serum samples is in a range from 93.3% to 112.7%. Therefore, the novel method for analyzing tyrosinase activity using carbon quantum dots as fluorescence probes is expected to be an effective method for clinically detecting tyrosinase.
