摘要：

Ethylenediaminedisuccinic acid (EDDS) was used to dissolve magnetite reductively. Fe2+ ions increased the dissolution rate, and this increase depended on the solution acidity, temperature and [EDDS]:[Fe2+]ratios. The EDDS-Fe2+ complex was able to dissolve magnetite film coated on an iron surface. Iron metal enhanced the dissolution of magnetite from its surface. However, metal exposed to the solution suffered more corrosion than iron free of magnetite.
