Abstract

Organic dyes in wastewater pose serious threats to public health and ecological systems and, therefore, it is critical to search for a strategy to handle them. In this study, we investigated systematically the effects of acidity and magnetic metal powders on the removal of organic dyes in aqueous solution. The results demonstrate that the pH is a determining factor for the removal of organic dyes in addition to the coordination interaction between organic dyes and metal ions dissolved from magnetic metal powders.
