Some samples may also contain a sulfate group.

In practice, the proteins are denatured in a solution containing a detergent (SDS).

He said that cancer lives in a highly acidic and de oxygenated environment

Aluminium sulfate (Al2(SO4)3 (H2O)18) is produced on the annual scale of several billions of kilograms.

Citrus fruits are the highest value fruit crop in terms of international trade.

Around 70 of the world's total citrus production is grown in the Northern Hemisphere, in particular countries around the Mediterranean and the United States, although Brazil is also one of the largest citrus producers.

In the gaseous form, this species is a significant pollutant, being the primary agent in acid rain.

Iron(III) sulfate (or ferric sulfate), is the chemical compound with the formula Fe2(SO4)3, the sulfate of trivalent iron.

It is thought that this species thrives in the acidic environment of caries and is thought to slow the development of dental caries.

Aluminium ammonium sulfate, which is also called ammonium alum, (NH4)Al(SO4)2 12H2O, is used as a mordant and in leather tanning.

Magnesium sulfate (or magnesium sulphate) is an inorganic salt (chemical compound) containing magnesium, sulfur and oxygen, with the formula MgSO4.

Worldwide trade in citrus fruits didn't appear until the 19th century and trade in orange juice developed as late as 1940.

One of the most common alternative treatments is berberine sulfate (found in Oregon grape root, goldenseal, yellowroot, and various other plants).

We want to talk about storing energy, and unfortunately the best thing we've got going is something that was developed in France a hundred and fifty years ago, the lead acid battery.

The Hartwell Paper argues that the Kyoto approach, based as it is on past experience with relatively simple environmental problems like acid rain, was always doomed to failure.

Evaluation of a strategy for environmentally sound management of hazardous and other wastes, such as lead acid batteries and biomedical and health care wastes, for impacts on the marine environment

In the United States, fossil fuel combustion for electric power generation is responsible for 65 of all emissions of sulfur dioxide, the main component of acid rain.

One issue in this synthesis route is the removal of the catalyst support via an acid treatment, which sometimes could destroy the original structure of the carbon nanotubes.

Yet, in China alone, coal mining accidents kill more than 2,000 people each year and coal is a leading cause of smog, acid rain, global warming, and air toxicity.

Dilute sulfuric acid is a constituent of acid rain, which is formed by atmospheric oxidation of sulfur dioxide in the presence of water i.e., oxidation of sulfurous acid.

The representative recalled the NGOs recent humanitarian mission to Cambodia where reconstructive surgical procedures and rehabilitation expertise was provided to acid burn victims.

More recent threats have come from environmental pollution on the banks of Yamuna River including acid rain due to the Mathura Oil Refinery, which was opposed by Supreme Court of India directives.

Unlike, say, acid rain or smog, it is not a conventional environmental problem. It is as much an energy problem, an economic development problem, or a land use problem.

Where limestone has been used, such as at Cwm Rheidol in mid Wales, the positive impact has been much less than anticipated because of the creation of an insoluble calcium sulfate layer on the limestone chips, binding the material and preventing further neutralization.

In the 1980s and 1990s, widespread concern about acid rain pollution in North America and Europe led to extensive research and assessment efforts that greatly enhanced understanding of long distance transport of sulphur and nitrogen oxide pollution.

(2006), when treating wastewater from metal refinery process (1.0 1.5 g NH4 N L and up to 22 g L of sodium sulphate), removed a nitrogen loading rate of 1.0 kg N m3 d with an efficiency of 95 in a system containing autotrophic granules.

What defines the Kyoto approach, of course, is a single minded focus on cutting carbon dioxide emissions. The Hartwell Paper argues that the Kyoto approach, based as it is on past experience with relatively simple environmental problems like acid rain, was always doomed to failure.
