Study onthe Removal of Copper Ion (Cu2+) From Industrial Wastewater by Using Ion Exchange Technique

Excess amount of copper (II) ion released through industrial wastewater to the
environment is very harmful. Presence of high concentration of copper (II) ion in
human body may lead to death and cause severe damage to other living species. Ion
exchange process is widely used nowadays and it is chosen for this study to treat
copper (II) from industrial wastewater in order to enhance water quality. Ion
exchange is a reversible chemical reaction wherein ion from the solution is
exchanged for a similarly charged ion attached to the resins. In this study, removal
of copper (II) ion using a strong acid and strong base resin is done in batch mode.
The aim of this study is to determine the optimum condition for copper (II) ion
removal from industrial wastewater based on certain criteria; effect of resin dose,
initial metal concentration, and pH. Experiments are performed under various
condition for resin dose effect (2g, 4g, 6g, 8g, and lOg) followed by the effect of
initial metal concentration (lOOOppm, 1500ppm, 2000ppm, 2500ppm, and
3000ppm). The experiment continues for different pH value (4, 7, and 10). The
result of removal efficiency is shown in graph and kinetic of the process also been
calculated. The effect of waste water treatment to the characterization ofthe resins is
determined by using Scanning Electron Microscope (SEM) and Fourier Transform
Infrared Spectroscopy (FTIR). Results from this project can help to design an
appropriate heavy metal removal technique by using ion exchange process in order
to minimize the negative impacts caused by industrial waste water.
