The word 'sulphate' is correct and usable in written English.
It is a chemical term that refers to a compound containing the sulfate ion (SO4²⁻), such as sodium sulfate or calcium sulfate. You can use the word 'sulphate' when discussing chemistry, specifically when talking about the properties or reactions of compounds containing the sulfate ion. Example: The experiment showed that when sodium sulphate (Na2SO4) is mixed with hydrochloric acid (HCl), a white precipitate of sodium chloride (NaCl) forms.
"When it comes to techniques that need to be field-tested, and where that will occur in places beyond national jurisdiction, such as sulphate aerosols, then inevitably we're looking at some kind of international governance framework," said Catherine Redgwell, a professor of international law at University College London and a member of the Royal Society working group on geoengineering.
A second category, known as solar radiation management tries to lower the amount of energy entering the Earth's atmosphere from the sun by, for example, spraying sulphate particles into the stratosphere or whitening clouds.
Most popular with the young homeless population is a substitute called skenan, capsules of morphine sulphate.
Shooting sulphate aerosols into the stratosphere would also work well, said the Royal Society, as previous volcanic eruptions have showed in the past.
It would create a small plume of sulphate particles and then measure the physical and chemical changes.For both the clouds and the stratosphere, the direct effects of the proposed experiments are tiny.
Ozone-destroying reactions happen faster on surfaces, such as those provided by sulphate particles, than they do in the open air.
For the sulphate-injection method to remain effective they would need to be replenished constantly for centuries longer than the lifetime of most countries.Then there are the side-effects.
At most, he reckons, the sulphate-injection approach could counteract half of the warming the world is expected to suffer over the next 100 years if carbon-dioxide emissions continue to rise unchecked.Other options seem even less effective.
Sulphate-based geoengineering would certainly slow down its recovery, but would not send it into reverse.
Sulphate-cooling is most effective in summer and least effective in winter.That, in turn, would lead to variations in local weather patterns.
There, they found a microbial ecosystem that appeared to be producing jarosite (a sulphate-based mineral) by oxidising rocks made of iron sulphide.
