Efficient Removal of Methylene Blue from Aqueous Solutions Using a Copper Oxide-Zirconia -Titania Ternary System
Abstract
Mixed-metal oxides are promising adsorbents for removal of methylene blue from waste streams due to their excellent textural and thermal properties. In this study, a CuO-TiO2-ZrO2 (5-47.5-47.5) ternary oxide was synthesized using the Pechini method and evaluated for adsorptive removal of methylene blue from aqueous solutions. The structural properties of the ternary oxide were determined using powder X-ray diffraction (XRD) and Fourier transform infrared (FT-IR) spectroscopy. Morphological properties were determined using scanning electron microscopy (SEM) while elemental analysis was done using energy dispersive X-ray (EDX) spectroscopy. The synthesized ternary oxide was poorly crystalline with copper oxide in a highly dispersed and amorphous state. The oxide consisted of irregular-shaped particles of different sizes that tended to agglomerate. The oxide was effective for adsorption of methylene blue. The optimal adsorption conditions were: a pH of 6, contact time of 20 min, dosage of 0.2 g and temperature of 45?C. The adsorption process was pseudo second order and fitted Langmuir and Temkin isotherms. The synthesized ternary oxide is a promising adsorbent for removal of methylene blue from aqueous solutions.
