During the production and processing, smelters produce a large amount of arsenic-containing wastewater, which makes it very difficult for enterprises to manage their environment and treat wastewater. Many smelters will carry out organic wastewater treatment operations. This type of wastewater…

How to efficiently extract copper from copper sulfate solution has become a core demand of hydrometallurgy, electronic waste recycling, chemical industry and other industries. Traditional methods such as replacement method and electrolysis method have pain points such as low efficiency,…

In the field of pharmaceutical intermediate synthesis and API purification, n-butanol, as a commonly used extraction solvent, often faces three major technical challenges in the extraction and separation process with the mother liquor water phase: low phase separation efficiency leads…

At present, the commonly used methods for treating nickel-containing wastewater are: chemical precipitation (using hydroxide or sulfide as precipitant), electrolysis, ion exchange, adsorption and oxidation-reduction. Although the above methods are effective in removing nickel ions, they all face problems such…

Dichloromethane (DCM) is the core solvent for the extraction of pharmaceutical intermediates. It has the advantages of strong solubility and moderate boiling point. However, the traditional process generally has problems such as high solvent residue (>500ppm), low separation efficiency (single-stage…

The working principle and performance of the centrifugal extractor are fundamentally different from the operating principle of the reactor. When choosing equipment, you should choose the appropriate extraction equipment according to the specific extraction needs. When choosing equipment, you should…
