Removal of Copper from Industrial Wastewater by Ion Flotation with Sodium Dodecyl Sulfate as Anionic Collector
Fouad S. M. Rashed [3] | Satyendra Nath [5]
Abstract: Copper removal from industrial wastewater is studied for environmental protection and copper recovery. The paper shows the copper removal of copper from industrial wastewater by ion flotation at a laboratory scale, using an anionic collector (Sodium Dodecyl Sulfate, SDS). The optimum values of the main variables affecting this process were determined. These variables are pH of copper solution, initial concentration of copper ions in sample, air flow rate and flotation time. An atomic adsorption spectrometry PERKIN ELMER model 2280 was used to determine the copper content of the wastewater. The copper removal efficiency was calculated with the equation R % = [ (C0 Cf) /C0]100, where C0 and Cf are the initial and final concentrations of copper ions in wastewater. Using the optimal conditions, high removal efficiency of copper ( 98 %) was obtained.
