Disclosed is a radiant catalytic ionization detoxification system including a gas-liquid mixer configured to gas-liquid mix air carrying radiant catalytic ionized Reactive Oxygen Species with liquid material to be detoxified, and a reaction tube configured to circulate the mixed gas-liquid mixture. The detoxification system of the present disclosure is applicable to water sterilization or aflatoxin removal in edible oils. The radiant catalytic ionization chamber in the system can provide the system with air containing Reactive Oxygen Species, wherein mesh panels coated with photocatalytic materials are configured inside the chamber body, which configuration not only increases the photocatalytic material content per unit volume, but also expands the light-exposed surface area due to uniform distribution of the photocatalytic materials on the mesh panels. The system uses a U-shaped tube as the reaction tube, and the length of the reaction tube can be freely designed according to the practical detoxification requirements.

Radiant catalytic ionization detoxification system and application thereof and radiant catalytic ionization detoxification method

Disclosed are a SA@CDs/g-CNcomposite material, a method for preparing same, and an application of the same to aflatoxin removal, which belong to the technical field of organic materials. The method for preparing a SA@CDs/g-CNcomposite material includes: adding a CDs/g-CNcompound into water, and uniformly dispersing same through ultrasonic treatment; adding sodium alginate, intensely stirring and fully mixing a mixture, and forming a pregel solution; transferring the fully mixed pregel solution into a mold, and freeze-drying the pregel solution to obtain sponge; and soaking the sponge in a CaCl) solution for gel, performing washing with deionized water, performing freeze-drying, and obtaining the SA@CDs/g-CNcomposite material. The SA@CDs/g-CNcomposite material prepared according to the present disclosure can effectively remove residual aflatoxin in foods, and is wild in effect, environmentally-friendly and safe.
