Studies on the Catalytic Action of Mineral Springs. II

Catalatic Action of Artificial Acidic Iron Solution. (2). Promotory Action of Al³⁺, Mg, ²⁺ and Ca²⁺

Abstract

Artificial mineral spring containing iron alum, with a large amount of aluminium or magnesium ion has stronger catalatic action than that which dose not contain these ions. In other words, aluminium and magnesium ions promote the catalatic action of iron ion. The mechanism of this accelerative action is thought to be the inhibition of effective concentration of sulfate ion by the presence of aluminium or magnesium ion, resulting in the increase of simple iron ion concentration.
