Sulfate ion

Sulfate ion (CAS 14808-79-8 ), also referenced as SO4²⁻, is the dissociated anion present across a broad range of inorganic sulfate salts used in industrial processing. It functions as a reactive species in pH buffering and coagulation chemistry.

The ion acts as a critical component in precipitation reactions rather than as a standalone purchasable compound. Buyers typically source it in the form of specific sulfate salts such as aluminum sulfate or ferrous sulfate.

These salts are selected based on the cation required for a given process, such as ammonium sulfate for specific applications. In water treatment, sulfate-bearing coagulants drive suspended solids removal and clarification.

These compounds are essential for municipal and industrial effluent systems to ensure effective purification. Mining operations rely on sulfate chemistry for leaching, metal precipitation, and tailings management across various sites.

In agriculture, sulfate salts deliver bioavailable sulfur to crops and are incorporated into fertilizer blends. These blends are specifically designed for targeting sulfur-deficient soils to improve overall crop yields and health.

Food-grade sulfate compounds serve as mineral supplements and processing aids in regulated food and feed formulations. Sulfate ion is not supplied as an isolated species; procurement is always through a specific salt form.

Available formats include powder, granule, crystal, or liquid solution depending on the industrial need. Grades available across sulfate salts include technical, food-grade ( FCC ), and feed-grade, depending on the salt selected.

Buyers should specify both the desired cation and the required grade when sourcing these chemical products. This ensures the material meets the necessary specifications for the intended industrial or food-related application.
