Description & Features

Descriptive:

WNX employs advanced automated production technology and uses high-quality raw materials to produce high-quality Ammonium Cerium Sulfate.

Key Features:

High Purity:Ammonium Cerium Sulfate contains no impurities from rare earth elements (such as iron, calcium, sodium), and the impurity content is low.

Good Solubility: Ammonium Cerium Sulfate can dissolve rapidly in water and strong acids.

Consistency: The strict batch management in the production of Ammonium Cerium Sulfate ensures stable quality for industrial large-scale production.

Chemical industrial catalyst: Cerium ammonium sulfate, as a powerful oxidant, is widely used in organic synthesis to catalyze various reactions, including the oxidation of alcohols, phenols, and ethers, as well as the Friedel-Crafts alkylation reaction. It is also an effective initiator for free radical polymerization reactions, which can be used to prepare materials such as PEGMA hydrogels.

Pond Phosphorus Remover: Based on its chemical properties, ammonium cerium sulfate can form a precipitate through the combination of cerium ions and phosphate ions, effectively removing phosphates from water bodies and helping to address the problem of water body eutrophication. Relevant studies have already applied it to prepare adsorbents for removing excessive fluoride from drinking water.

Batteries and Energy Materials: In the field of new energy, high-purity ammonium cerium(IV) sulfate can be used to prepare cerium oxide (CeO₂) nanomaterials. These materials show potential application value in solid oxide fuel cells (SOFC) and chemical sensing. Their unique redox properties (Ce⁴⁺/Ce³⁺) play a role in energy conversion and storage.

Chemical synthetic intermediates: As an important cerium source, ammonium cerium(IV) sulfate is a key precursor for synthesizing other cerium compounds (such as cerium oxide). It is also a commonly used analytical reagent in spectroscopic analysis for determining oxidizable substances such as nitrite, iodide, and low-valent iron salts (e.g., the Sandell-Kolthoff reaction).
