抄録

Ferric chelate of EDTA has been used as a photographic bleaching agent for the past five decades. In spite of its long history, EDTA is not biodegradable, therefore, new chelates which are environmentally safe are demanded. Three essential factors are required for such post-EDTA compounds: chelating ability equal to that of EDTA, practical biodegradability in environment and reasonable production costs.<BR>In this review, we will explain several aspects of our approach to the new post-EDTA chelates with respect to detergent components (builder), where biodegradability is a more critical factor than in the field of photographic chemicals.
