In the fields of chemical engineering and environmental protection, potassium permanganate, a common strong oxidant, is experiencing an unprecedented wave of innovation. With the tightening of environmental protection policies and technological progress, the production process of potassium permanganate is developing in a greener and more efficient direction, and its application fields are also expanding from traditional disinfection and water treatment to high-tech directions such as alkaline wastewater treatment and metal activation catalysis.
01 Production Process Innovation: From Relying on imports to Independent research and development
The production technology of potassium permanganate is undergoing a profound green transformation. For a long time, environmental issues in the production process of potassium permanganate have been a pain point in the industry, but this situation is changing.
Chongqing Changyuan Chemical Group Co., LTD., as the world's largest producer of potassium permanganate, is constantly carrying out technological innovation. The company has developed an efficient method for preparing potassium permanganate. By modifying the raw materials and optimizing the production process, it has achieved multiple goals of cost reduction and efficiency improvement. In terms of specific production processes, domestic enterprises have already possessed the world's most advanced potassium manganate preparation technology. The production of potassium manganate mainly consists of two methods: solid-phase calcination and liquid-phase oxidation. Through continuous production practice and improvement, the production technology has made considerable progress. Purity determines success or failure. Many low-priced potassium permanganates on the market contain impurities such as chlorides and iron ions, which are prone to oxidation and deterioration, and may even produce harmful by-products. The laboratory-grade high-purity products have been confirmed by third-party testing institutions to have a purity of 99.5%, and the content of heavy metals is more than ten times lower than the national standard limit.
Comparative tests show that the high-purity product dissolves rapidly, the solution is clear, and its stability is nearly 40% higher than that of ordinary industrial-grade products.
02 Frontier Application Expansion: From water Treatment to High-tech Fields
Breakthrough in alkaline wastewater treatment
In the field of water treatment, the application of potassium permanganate is no longer limited to traditional disinfection and oxidation. A research team from Nanjing Tech University has developed a potassium permanganate intercalated magnesium-aluminum layered dihydroxide (MgAl-MnO4-LDH), successfully solving the problem that the oxidation efficiency of potassium permanganate is limited under alkaline conditions. This new material can maintain excellent phenol oxidation efficiency within a wide range of pH 6.35 to 12. At pH 10, the removal rate of 50ppm phenol is as high as 70.51%, which is 14 times that of potassium permanganate with the same manganese content. This provides an efficient and reliable technical solution for treating alkaline phenolic wastewater generated in industries such as coking, papermaking, and gas production.
Metal oxide activation technology
In the research project "Activation of Potassium Permanganate by Metal Oxide-type Lewis Acids", Professor Xu Aihua's team from Wuhan Textile University solved the problem of the activation efficiency of potassium permanganate in related reaction systems and explored the possibility of metal oxide-type Lewis acids in optimizing the performance of potassium permanganate and expanding its application fields. This research provides a new idea for the efficient activation of potassium permanganate and is expected to further expand its application scope.
03 Precise Application in aquaculture and disinfection fields
Optimization of fishing net disinfection technology
The problem of fishing nets serving as carriers for microbial transmission has long plagued the aquaculture industry. Researchers developed a 96-well microplate method to systematically evaluate the disinfection effect of KMnO4 (10-100 ppm) against Vibrio parahaemolyticus and drug-resistant Escherichia coli. Research has found that treatment with 30 ppm KMnO4 for one minute can effectively inactivate pathogens without damaging the nylon net material, providing important technical support for the biosecurity of aquaculture. This high-throughput screening method of microplates not only significantly enhances the efficiency of optimizing disinfection parameters, but also provides an economical and efficient solution for blocking the spread of pathogenic and drug-resistant bacteria in aquaculture.
04 Global Markets and Future Trends
With the tightening of environmental protection policies, the market concentration of the potassium permanganate industry has continued to rise, and the development of technology and processes has driven industrial upgrading. Chongqing Changyuan Chemical Group, as the largest potassium permanganate manufacturer in China and also the world's largest, accounts for over 60% of the global production capacity. The global market for high-purity potassium permanganate also shows a stable growth trend. According to market research reports, the main application of high-purity potassium permanganate is as an oxidant in industries such as pharmaceuticals, water treatment, metal surface treatment, and disinfectants.
In the future, with the promotion of green production processes and the expansion of new application fields, the potassium permanganate industry will continue to develop towards high quality and high added value.
