Purified sulfur (sulfur depuratum) is prepared by washing sublimed sulfur with ammonia. It is a fine yellow powder. It was formerly used as a laxative, but this application is rare today. [1] Precipitated sulfur (sulfur praecipitatum) is prepared by boiling sulfur and calcium oxide in water and then precipitating with hydrochloric acid. It, too ...
Historically, flowers of sulfur were extensively used medically to cure ailments, particularly skin diseases. [6] Sublimed sulfur was applied topically for skin diseases, but was also taken orally or injected for treatment of other diseases. Flowers of sulfur is seen to inhibit bacterial growth in tubercle bacilli, [7] and S. aureus, and C ...
Controlled release fertilizers are traditional fertilizers encapsulated in a shell that degrades at a specified rate. Sulfur is a typical encapsulation material. Other coated products use thermoplastics (and sometimes ethylene-vinyl acetate and surfactants, etc.) to produce diffusion-controlled release of urea or other fertilizers.
Treatment of sulfur with hydrogen gives hydrogen sulfide.When dissolved in water, hydrogen sulfide is mildly acidic: [5] H 2 S ⇌ HS − + H +. Hydrogen sulfide gas and the hydrosulfide anion are extremely toxic to mammals, due to their inhibition of the oxygen-carrying capacity of hemoglobin and certain cytochromes in a manner analogous to cyanide and azide.
The Sulphur Institute connects these sulfur producers with sulfur's largest consumer markets (fertilizers and construction materials), transporters, traders, and service providers. [3] Today, The Sulphur Institute's member companies include a host of companies from five continents involved with producing, consuming, trading, adding value, or ...

A 15-ton crop of onions uses up to 19 lb of sulfur and 4 tons of alfalfa uses 15 lb per acre. Sulfur abundance varies with depth. In a sample of soils in Ohio, United States, the sulfur abundance varied with depths, 0–6 inches, 6–12 inches, 12–18 inches, 18–24 inches in the amounts: 1056, 830, 686, 528 lb per acre respectively. [98]
The sulfur coating process was originally developed by the Tennessee Valley Authority. [1] Sulfur-coated urea products can only be applied in granular form, and thus cannot be applied via liquid fertilization methods. It is not uncommon to find empty sulfur husks in turf once the nitrogen is released.
