摘要：

The kinetic reactions of ferron (8-hydroxy-7-iodo-5-quinoline-sulfonic acid) with unneutralized and partially neutralized Al solutions in the presence of various inorganic anions were investigated for the purpose of differentiating mononuclear and polynuclear Al. Development of a general order reaction function indicated that ferron interactions with Al were modeled best by second-order rate expressions. Ferron interactions with partially neutralized Al-anion solutions were described by two simultaneous second-order reactions that provided the rate of Al-polymer interactions with ferrous, k//b, and the mole fraction of mononuclear Al species present, f//a.
