As the global energy transition accelerates, vanadium—often referred to as the “vitamin of metals” and the “MSG of modern industry”—is experiencing unprecedented demand growth. In addition to its indispensable role in steelmaking, chemicals, aerospace, and pharmaceuticals, vanadium redox flow batteries…

In the fields of coal coking, BTX (benzene, toluene, and xylene) production, and fine chemicals manufacturing, BP wastewater has long been a challenging issue for environmental engineers. High concentrations of phenols, aromatic amines, sulfur-containing organic compounds, and ammonia nitrogen make…

With the rapid advancement of global industrialization, the generation of zinc-containing waste—such as zinc dross, spent batteries, and electroplating sludge—continues to increase year by year. These wastes are not only an environmental challenge but also a valuable “urban mine” rich…

N-Methyl-2-pyrrolidone (NMP), as an excellent polar solvent, is widely used in high-end manufacturing industries such as lithium batteries, semiconductors, and polymer materials. However, the large volume of NMP-containing wastewater generated after its use not only creates environmental pressure but also…

Naphthalenesulfonic acid is an important chemical intermediate based on a naphthalene ring structure linked with sulfonic acid groups. It is widely used in the production of dyes, pharmaceuticals, pesticides, concrete water reducers, and other chemical products. During the manufacturing process…

Battery black mass, obtained after crushing and sorting spent lithium-ion battery cathode materials such as lithium nickel cobalt manganese oxide (NCM) and lithium cobalt oxide (LCO), contains valuable metals including nickel, cobalt, lithium, and manganese. However, these metals are closely…
