Abstract

In this study, Copper oxide as a good and inexpensive adsorbent has been introduced and used for the removal of erythrosine and red carmoisine dyes from several water solutions successfully. The effect of various parameters such as pH, dye concentration, amount of adsorbent, contact time and temperature on removal processing was investigated. Adsorption isothermal data could be interpreted by the Langmuir and Freundlich, isotherm models.
