Phosphate interference during in situ treatment for ...

A significant obstacle exists, however, due to the interference of phosphate since phosphate competes for adsorption sites on oxidized iron precipitates. A lab-scale test including 0.5 mg L−1 phosphate showed negligible removal of arsenate. In situ treatment by air sparging demonstrates considerable promise for removal of arsenic from ...

Matter cycles and pollution - Lenntech

Humans cause environmental problems, by interfering with the nitrogen cycle in several ways. During fuel combustion various compounds are released, among which nitrogen oxides (NO x).Nitrogen oxides react with oxygen in air, so that nitrous oxide gas (N 2 O) is formed. Nitrous oxide is a greenhouse gas, which enhances the earth's temperature when it is present in the atmosphere too extensively.
