In steel production, stainless steel production generates a large amount of pickling sludge, which contains high concentrations of valuable metal ions such as Fe3+, Cr3+, and Ni2+. If this large amount of sludge is not promptly treated, it will seriously…

Centrifugal extractor is a commonly used extraction equipment for extracting organic matter from organic wastewater in chemical plants. It uses solvent extraction to effectively remove organic matter in wastewater, reduce COD, and facilitate subsequent biochemical treatment. H-acid is a very…

In the fields of chemical industry, pharmaceuticals, bioenergy, etc., n-butanol is an important solvent and chemical raw material, and its efficient and high-purity separation and recovery are crucial. However, the azeotrope formed by n-butanol and water complicates traditional distillation separation…

With the booming development of industries such as electroplating, metallurgy, and battery manufacturing, the treatment of large amounts of zinc-rich waste acid has become an environmental and resource problem that needs to be solved urgently. Traditional chemical precipitation methods are…

In cutting-edge fields such as and high-purity metal preparation, tributyl phosphate (TBP) plays an irreplaceable role as a highly efficient and selective extraction agent. With its unique molecular structure, TBP can precisely “capture” target metal ions in solution, enabling the…

Sulfolane, a highly effective solvent, is widely used in the chemical and pharmaceutical industries. However, its wastewater discharge has become a major environmental challenge for these companies. Traditional recovery methods are inefficient, energy-intensive, and result in significant solvent loss, leading…
