The photochemical reaction instrument is divided into the following categories: 1. Micro reactor: It can minimize the harm of the experiment to the experimenter, the reaction volume is 5 ~ 15ml, the cold trap, the reactor, the lamp source is 5.5W Low voltage, cold light source mercury lamp, 220V model. 2. Small-volume reactor: A high-efficiency UV mercury lamp is used as the lamp source. Among all the radiation energy, the ultraviolet energy: 40-48%, the visible light: 40-43%, and the rest is balanced by infrared light, from 250ml to 5000ml. The volume type is optional, there are many types of filters. The power supply is available. The output power can be adjusted. The protection cabinet has an observation window, and there are protection filters, various types of reaction vessels and light source volume: 250mL, 500mL, The 1000mL kettle body has a single-walled, jacketed, jacketed container with a bottom discharge valve. The optional protection box is controlled to open on the outer wall of the box. The operator can operate the reaction process with minimal radiation to achieve protection. The purpose of personnel 3. Parallel reactors: Small parallel reactors can perform 8 parallel reactions at the same time, the transillumination table cannot rotate, and there is a fan at the bottom to blow up the heat. Large parallel reactors can conduct 51 parallel patterns at the same time, divided into inner and outer circles , The inner ring can hold 18 borosilicate filter tubes and the outer ring can hold 33 tubes. The potassium chromate and sodium cyanide content of all filter tubes is less than 3%, which can effectively improve the parallel The efficiency of the reaction. The transillumination table can be rotated, so that each sample receives the same energy at the same time, and the reaction conditions of each sample can be unified (such as temperature, light energy, etc.) to achieve the reproducibility of the test conditions
4. Photocatalytic oxidizer (ultraviolet light) Used to determine the content of inorganic substances in nitrogen oxides, carbon oxides, and phosphorus compounds, and to pass excess oxygen into the slag dissolved in water, while irradiating at the same time, within one hour Convert phosphorus trichloride into cations and oxides into CO2. Other applications include metal-containing organic matter, determining the TNT content in water, and providing organic-free samples for agriculture and fertilizer analysis. The main components include: a sample rack that can hold 12 sample tubes, or a coil wound on the lamp jacket, the material passes through the coil to achieve the purpose of irradiating the material. 1200W medium-pressure mercury lamp, the power supply can set the time and irradiation power. 5. The thin-film photochemical reactor (falling film) special glass reactor can be used for falling film photochemical reaction. The specific principle is to pump the reacted materials to a high place through the pump and enter the upper edge of the reaction channel when the high place After the flange, the material is illuminated by the light source as it flows down the wall of the tube. It can be taken from the bottom while reacting. The flow rate can be controlled between 35cc / min ~ 300cc / min, the minimum volume of the reactor is 100ml, the maximum volume is 2L, and the reactor can withstand the pressure of 0.7Kg / cm2.
