Reactivity of iodide in volcanic soils and noncrystalline soil constituents

Reaction of iodide [I−(aq)] with a series of volcanic-ash soils was compared with reaction onto noncrystalline materials that constitute much of the inorganic fraction of these soils, Our hypothesis is that these high-surface-area materials account for iodide retention by providing sites for anion e...

Description
Summary:Reaction of iodide [I−(aq)] with a series of volcanic-ash soils was compared with reaction onto noncrystalline materials that constitute much of the inorganic fraction of these soils, Our hypothesis is that these high-surface-area materials account for iodide retention by providing sites for anion exchange. Iodide sorption onto imogolite and ferrihydrite is rapid (
