Abstract

The invention relates to the technical field of carbon quantum dot preparation, and discloses a device for preparing carbon quantum dots by a semi-automatic electrochemical stripping method, which comprises a base, a reaction tank is fixedly mounted at the top of the base, a fixed table is fixedly mounted at the top of the reaction tank, and a clamping plate is fixedly mounted at the top of the fixed table. A reciprocating stirring mechanism is arranged in the base, a fixed mounting mechanism is arranged on the clamping plate, and a liquid level control mechanism is arranged in the reaction tank. According to the device for preparing the carbon quantum dots through the semi-automatic electrochemical stripping method, the PCB connects the first carbon rod and the second carbon rod through the wire to form a loop, if the current flowing through the carbon rods is abnormal in the preparation process, the circuit part has a reminding function such as buzzer buzzing and disconnection of a branch circuit where the carbon rods are located, and the carbon quantum dots can be prepared through the mounting holes in the clamping plate. The temperature sensor is connected with the PCB through a wire, and the temperature sensor is arranged in the reaction tank and can monitor the reaction temperature of a solution in the tank.

Description

technical field [0001] The invention relates to the technical field of carbon quantum dot preparation, in particular to a device for preparing carbon quantum dots by a semi-automatic electrochemical stripping method. Background technique [0002] Carbon quantum dots (Carbon Quantum Dots, CQD) are composed of dispersed spherical carbon particles with extremely small size (below 10 nm) and a new type of nano-carbon material with fluorescent properties. Carbon quantum dots have many advantages such as excellent optical properties, good water solubility, low toxicity, environmental friendliness, wide source of raw materials, low cost, and good biocompatibility. Carbon quantum dots are widely used, and have good application prospects in many fields such as biological imaging, environmental monitoring, chemical analysis, ion detection, catalyst preparation, energy development, and safety equipment. Appropriate size, low cost and good biocompatibility of carbon quantum dots are cr...

AI Technical Summary

Problems solved by technology

Compared with the existing preparation equipment, the temperature is not easy to control during the reaction process, which will affect the reaction rate, and the reaction solution is volatile as the temperature rises, so it needs to be replenished in time to adjust the concentration of the solution, and the liquid needs to be added manually, which takes a lot of time

It is cumbersome to take out the product from the reaction tank, and it is inconvenient to clean the carbon particles at the bottom of the deposit

During the reaction process, due to the black color of the solution, the carbon rod consumption is unknown, so it cannot be monitored and replaced in time
