Abstract
Removal of heavy metals from wastewater is a major ecological problem. Adsorption process for the removal of heavy metal from synthetic wastewater by using low cost adsorbent (Sulphuric acid treated Sugar cane bagasse). It is cost effective method and also it do not cause the any type of environment pollution. Concentrations vary between 5 – 20 ppm. As concentration increases % removal decrease at particular stage after that rate of adsorption constant. The percentage of adsorption of each metal ion, the mass of Bagasse varied from 2 to 20 g/L, the pH of the solution being maintained to 5 with a contact time of two hours. Contact time on the adsorption of copper and nickel ions on the Sugarcane Bagasse was carried out at pH 5 with a Bagasse mass of 20 g/L while varying this parameter from 0.5 to 5 hours. The percentage of each metal adsorbed as function of the pH for a mass of untreated Bagasse of 10 g/L and a Natural Adsorbent, Sugarcane Bagasse, Heavy Metal Removal, Wastewater Treatment, Adsorption
Process. time of contact of two hours. The percentage of each metal adsorbed increases with the pH. The maximum adsorption
of each and every metal ion found at pH range from 5 to 6.
