Speciation and removal of zinc from composted municipal solid wastes

Article Abstract:

The zinc content in the composted organic fraction of municipal solid waste containing 50,000 mg/kg of cellucotton and 7,980 mg/kg of zinc was reduced to1,240 mg/kg by the double extraction of the waste with sodium diphosphate(V).

Lead immobilization using phosphoric acid in a smelter-contaminated urban soil

Article Abstract:

Soil samples from a lead-contaminated site in Joplin, Missouri are treated using phosphoric acid to reduce the poisonous lead to a relatively harmless compound similar to chloropyromorphite. Graphs show the reduction of lead in the soils over a period of days.
