Study the removal of copper ions from wastewater using an array of horizontal rough vibrating zinc discs
摘要
The removal of copper ions from synthetic wastewater was investigated using cementation on arrays of oscillating smooth and rough (corrugated) zinc discs under different conditions initial copper ions concentration, vibration intensity (frequency, amplitude), spacing between zinc discs, surface roughness (peak to valley height) and temperature. The results showed that the mass transfer coefficient increased significantly with increasing vibration intensity, initial copper ion concentration, disc spacing, degree of surface roughness, and temperature. Rough (corrugated) discs exhibited significantly higher mass transfer rates than smooth discs, emphasizing the critical role of surface roughness in enhancing diffusion-controlled cementation. The effect of temperature was found to fit Arrhenius equation with an activation energy of 2.58
