The chemical reaction method is The program is as follows. C6H5OH 7O2=6CO2 3H2O By measuring the chemical oxygen demand (COD) in the phenol wastewater before and after the reaction, the removal of the chemical oxygen demand (COD) in the phenol wastewater is calculated Rate to characterize the activity of the catalyst.4 Reagents or materials4.1 Phenol. The purity is greater than 99.0%. 4.2 Deionized water. secondary water specified in GB/T 6682. 4.3 Oxygen. The purity is greater than 99.5%. 4.4 Nitrogen. purity greater than 99.5%.5 Test device5.1 Device The schematic diagram of the catalyst activity test device for wet catalytic oxidation of organic wastewater is shown in Figure 1. 5.3 Check Under normal circumstances, the parallelism and reproducibility of the test device are measured at least once a year with reference samples or reserved samples. The provisions of Chapter 7 and Chapter 8.6 samples6.1 Laboratory samples Obtained according to GB/T 6679. 6.2 Sample Take an appropriate amount of laboratory samples and place them in an agate mortar and grind them, so that all the samples pass through a 75μm test sieve (according to GB/T 6003.1- 2012 R40/3 series), put the ground sample into a weighing bottle, dry it at 110℃±5℃ for 5h, take it out and place it in a desiccator, cool Bring to room temperature and set aside. 6.3 Sample Weigh 1g catalyst sample, accurate to 0.001g, and set aside.7 Test procedureWarning---The test materials and reagents involved in this standard have toxic, flammable, and explosive hazards to human health and safety, and must be strictly To prevent the test device from leaking, open flames are strictly prohibited on the site, and necessary fire extinguishing equipment and exhaust equipment should be equipped with preventive facilities; the autoclave is strictly prohibited The disassembly operation is carried out under pressure; this standard does not reveal all possible safety issues, the user should strictly follow the relevant regulations and use it correctly, and is responsible Take appropriate safety and health measures. 7.1 Raw material preparation Weigh 5g of phenol, accurate to 0.1g, and place it in a 1000mL volumetric flask. Place the volumetric flask in a 75℃ water bath and use deionized water Make the volume to 1000mL. 7.2 Filling the reactor Add.200 mL of raw materials and catalyst sample (6.3) to a 500 mL autoclave in sequence, close the cover, and tighten the nuts evenly After that, connect it to the test device. 7.3 Leak test Open the nitrogen valve, introduce nitrogen to the test device, increase the pressure of the test device to 2.0MPa, and close the inlet and outlet valves of the test device. As in If the pressure drop within 30min is less than 0.05MPa, the test device is considered to be sealed. Open the outlet valve of the test device to reduce the pressure of the test device to normal Press and insert the temperature measuring thermocouple into the thermowell. 7.4 Gas replacement and activity measurement Replace the test device with nitrogen three times. After the exhaust pressure is reduced to normal pressure, change to oxygen, replace three times, and then exhaust and reduce the pressure to normal pressure. The kettle should be heated. When the reaction kettle is heated to 180°C, oxygen is introduced, and the pressure of the test device is increased to 2.0MPa within 1 min, and controlled and maintained The pressure of the reactor is 2.0MPa, the temperature is 180℃±2℃, and the stirring speed is 1200r/min. After 1h, the test was ended. 7.5 Parking Turn off the oxygen, turn on the cooling water, and release the pressure after the reactor has cooled to below 60°C. After replacing the test device with nitrogen three times, sample and divide After analysis, clean the reactor body with deionized water. 7.6 Determination of Chemical Oxygen Demand (COD) Take the product collected in 7.5 as the test sample. Draw 10.00mL of the tested sample, place it in a 100mL volumetric flask, and dilute to After 100mL, according to GB/T 32208, determine the chemical oxygen demand (COD) in the product (in terms of mass concentration). Follow the above steps at the same time, Determine the chemical oxygen demand (COD) in raw materials.8 Test data processingThe catalyst activity is calculated based on the removal rate E of chemical oxygen demand (COD), calculated according to formula (1). E=ρ1 -ρ2 ρ1 ×100% (1) Where. ρ1---The chemical oxygen demand (COD) in the raw material, in milligrams per liter (mg/L); ρ2---The chemical oxygen demand (COD) in the product, in milligrams per liter (mg/L). Take the arithmetic average of three consecutive determination results as the determination result, and the range of the three determination results should not exceed 3%. 0202- T/ ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 38602-2020_English be delivered?Answer: Upon your order, we will start to translate GB/T 38602-2020_English as soon as possible, and keep you informed of the progress.
