  • ASTM D516 - 11 standard test method for sulfate ion in water

    The determination of sulfate is important because it has been reported that when this ion is present in excess of about 250 mg/L in drinking water, it causes a cathartic action (especially in children) in the presence of sodium and magnesium, and gives a bad taste to the water. 1. Scope 1.1 This turbidimetric test method covers the determination of sulfate in water in the ...

  • University finds metal sulfide solution for nuclear waste

    Nuclear power has advantages, but, if this method of making power is to be viable long term, discovering new solutions to radioactive waste disposal and other problems are critical. Otherwise nuclear power is unlikely to become mainstream. A team of Northwestern University chemists is the first to focus on metal sulfide materials as a possible source for nuclear waste remediation methods. Their ...

  • Ground glass solution for cleaner water

    British science has led to a use for waste glass that cannot be recycled that could help clean up polluted waterways by acting as an ion-exchange filter to remove lead, cadmium and other toxic metals. Details are published in a forthcoming issue of the International Journal of Environment and Waste Management. Only a fraction of waste glass bottles and jars can be recycled, partly because much ...

  • Coolant destruction is 4000 times cleaner than expected

    Emissions from a plant built to destroy one of Britain’s biggest environmental hazards have been up to 4000 times cleaner than its designers expected. Engineers believed they could reduce the levels of radioactivity in effluent from a new liquid metal destruction plant by up to a thousand times at most. But the £15 million plant built at Dounreay in northern Scotland has reported decontamination ...

  • `Oranges` can clean up and recover phosphorus

    Phosphorus is a common industrial pollutant in water, as detailed in a European Commission report to Parliament in 2004. A new technique for removing phosphorus from industrial wastewater uses waste products from orange juice production and allows the phosphorus to be re-used. It may help industries comply with the Water Framework and Urban Wastewater Directives3, as well as relieving pressure on ...
