Sulphate
Sulphate. In chemistry, a sulphate ( sulfate in US English) is a salt of sulphuric acid. The sulphate ion is a group of atoms with the formula SO 4 and two negative charges. It consists of a central sulphur atom surrounded by four equivalent oxygen atoms. It occurs when sulfuric acid is deprotonated twice. If it is only deprotonated once, the ...
Sulfate | Definition, Formula & Structure
Sulfur has 6 valence electrons. Each oxygen atom has 6 valence electrons. Since sulfate has 4 oxygen atoms, that equals 24 valence electrons. Sulfate has a charge of 2 −, which means it has an ...

A new diffusion model of sulfate ions in concrete
Based on the experimentally obtained results, a new diffusion model for sulfate ions was developed, taking into account the influence of the evolution of sulfate-induced damage on the diffusion of ions. The evolution of damage with immersion time and concentration of sulfate ions can be determined using ultrasonic tests.
Tube-in-tube membrane photoreactor as a new technology to boost sulfate
S 2 O 8 2– direct reaction with pharmaceuticals, in the absence of UVC light, considering the highest dose of S 2 O 8 2– (0.59 mM), takes place at a very low rate resulting in conversions of 4–5% (Fig. 1 b), as reported elsewhere (Cvetnić et al., 2019).. As expected, the UVC/S 2 O 8 2– system showed significantly higher degradation values of …
Sulfate in Drinking Water | Unregulated | US EPA
EPA estimates that about 3% of the public drinking water systems in the country may have sulfate levels of 250 mg/L or greater. The Safe Drinking Water Act (SDWA), as amended in 1996, directs the U.S. Environmental Protection Agency (EPA) and the Centers for Disease Control and Prevention (CDC) to jointly conduct a study to …
A new interpretation of sulfate activation of rabbit muscle …
It is widely known that sulfate ion at high concentration serves like an allosteric activator of glycogen phosphorylase (GP). Based on the crystallographic studies on GP, it has been assumed that the sulfate ion is bound close to the phosphorylatable Ser 14 site of nonactivated GP, causing a conformational change to catalytically-active GP. However, …

The new self-healing system introduces two response modes, namely sulfate triggering and mechanical stimulation, to address concrete cracks at various ages. Even for cracks that emerge 60 days later, the crack healing ratio can still reach 80%.
Solubility of Barium Sulfate in Formate Brines
Abstract. It has been known since the 1930's that concentrated brines release barium into solution from barite. The amount of barium released into solution is a function of the molar salt concentration, brine type, temperature, and pressure. Brines containing very high molar concentrations of solute are the most effective at solubilizing …

Corrosion of iron by sulfate-reducing bacteria: new views …
Under anoxic conditions (e.g., in oil and gas pipelines), sulfate-reducing bacteria (SRB) are commonly considered the main culprits of MIC. This perception largely stems from three recurrent observations. First, anoxic sulfate-rich environments (e.g., anoxic seawater) are particularly corrosive. Second, SRB and their characteristic corrosion ...
