In chemical production, wastewater treatment, and salt lake resource development, the precise removal of chloride ions has always been a key factor in determining product quality and environmental compliance. Chloride-containing solutions are often characterized by strong corrosiveness, a high tendency…

In the synthesis and purification processes of pharmaceutical intermediates, manufacturers generally face three major technical challenges: difficulty in breaking emulsified layers, resulting in slow phase separation; significant evaporation of organic solvents, causing environmental and cost pressures; and degradation or loss…

With the rapid development of the global new energy industry, lithium, as the core raw material for power batteries, has become increasingly strategic. Among various lithium resources, salt lake brine lithium resources have become an important feedstock for global lithium…

For aniline manufacturers, wastewater treatment is not only a necessary step to comply with environmental regulations but also a potentially overlooked source of value. Aniline production wastewater typically contains a certain concentration of nitrobenzene—a chemical intermediate widely used in the…

With the rapid development of the PCB manufacturing industry, alkaline etching solution has become one of the largest sources of wastewater generated during the production process. This wastewater contains a high concentration of copper ions. Direct discharge not only causes…

Ethyl acetate is a widely used organic solvent in the fine chemical industry. Due to its slight mutual solubility with water, the ethyl acetate-water system often presents challenges in terms of both separation efficiency and economic performance during extraction and…
