Role of dust alkalinity in acid mobilization of iron

Atmospheric processing of mineral aerosols by acid gases (e g SO2 HNO3 N2O5 and HCl) may play a key role in the transformation of insoluble iron (Fe in the oxidized or ferric (III) form) to soluble forms (e g Fe(II) by dynamically solving the mass transfer equations In the
