In the field of rare metal metallurgy and advanced material preparation, the separation and extraction of rubidium and cesium has long been recognized as a technical challenge. Traditional methods such as mixer-settler extraction, ion exchange, or precipitation not only involve…

H-acid is an important intermediate in the dye industry. The wastewater generated during its production process is extremely complex and has the following characteristics: Direct biochemical treatment of this type of wastewater is largely ineffective, while advanced oxidation processes or…

In the fields of chemicals, agriculture, food, pharmaceuticals, and even new energy, the purity of phosphoric acid—as a fundamental raw material—directly determines the added value and scope of its applications. Owing to its advantages of low energy consumption and low…

In modern chemical, pharmaceutical, environmental protection, and hydrometallurgical industries, how to efficiently and precisely separate and purify target components from complex liquid mixtures has always been a core challenge in production processes. As a classical yet powerful separation method, liquid–liquid…

With the evolution of lithium-ion battery cathode materials toward high-nickel ternary systems, extremely stringent purity requirements have been imposed on manganese sulfate—where the mass fractions of impurities such as potassium, sodium, calcium, and magnesium must be controlled below 5.0×10⁻³%. Traditional…

Salt lake brine is rich in resources, containing high-value elements such as lithium, boron, potassium, and magnesium. Among them, boron is an important industrial raw material widely used in the chemical, metallurgical, ceramic, and new energy industries. Efficient and economical…
