Kinetics of copper adsorption from wastewater by lignite
Апстракт
Kolubara lignite was used as a natural and low cost adsorption material for removal of copper (Cu2+) from the aqueous solutions. As a method, batch adsorption procedure was applied. Results show that domestic lignite is good adsorbent material since about 90 % of copper cations were removed in 5 minutes of contact time from the solutions of low copper concentration (50 mg/l) regardless the adsorbent amount, while the same effect of adsorption was achieved in 60 minutes
in case of solutions with high concentrations of copper (330 mg/l). Optimum removal of copper ions was achieved at pH = 5.0. The study proved that tested lignite is very efficient adsorbent material. This behavior can be explained by FTIR spectrum despite a small specific surface area of lignite. Many bands are attributed to the functional groups involved in chemisorption and ionic exchange, basic mechanisms of copper adsorption.
