At pH 5.0 more Pb was adsorbed than Zn or Cd. Soluble Zn, Pb and Cd concentrations in soils after 600 hours of reactions decreased almost linearly with pH. This was attributed to increasing charge density of the soils and the hydrolysis of metal cations. At pH below 6.5, the likely control on Zn2+ activities in soil solution was Franklinite (ZnFe2O4), but between pH 7 and 9, Zn2+ activities in soil solution approached the solubility isotherm of Hopeite (Zn3(PO4)2. The log Pb2+ - pH activity isotherms indicated that at pH Hersteller: LAP Lambert Academic Publishing Marke: LAP Lambert Academic Publishing EAN: 9783844382617 Kat: Hardcover/Naturwissenschaften, Medizin, Informatik, Technik/Chemie/Physikalische Chemie Lieferzeit: Sofort lieferbar Versandkosten: Ab 20¤ Versandkostenfrei in Deutschland Icon: https://www.inforius-bilder.de/bild/?I=LVp2UhrUXJqHPCY9PKNe7zUuYSq%2BigzwpU4pD0KpbX0%3D Bild:
