Abstract

High concentration Co(II) in wastewater is highly toxic and responsible for various diseases to living beings. A very simple, eco-friendly and coast effective method for its removal is the use of Mangifera indica bark substrate. It is found to have good adsorption capacity. The studies shows that sorption of Co(II) increases with pH and found maximum at pH 5 for an optimum contact time of 60 minutes. The effect of concentration indicates that the bark substrate can remove Co(II) at lower concentration. The adsorption also increases with increasing doses of bark substrate. The presence of light metal ions in solution interfere with adsorption of Co (II) ions. The column study reported that about 60% of the metal ions remove instantaneously when passed through a packed column of bark substrate.
