Adsorption of nickel from aqueous solution by coir based adsorbent, puresorbe.
Environ Technol. 2006 Jan; 27(1):15-24.ET

Abstract

The effectiveness of adsorption for nickel removal from wastewater had made it an ideal alternative to other expensive treatment options. This paper deals with an investigation on coir based adsorbent (Puresorbe) in the removal of nickel from the aqueous solutions. The adsorption of nickel was carried out by varying the parameters such as agitation time, metal concentration, adsorbent dose, temperature and pH. The experimental isotherm data were analyzed using the Langmuir and Freundlich isotherms. Adsorption followed a second order rate expression for the particle size 250-500 microm at pH 6. The monolayer adsorption capacity was 15.31 mg nickel per gram of puresorbe. Thermodynamic parameters show the endothermic nature of nickel adsorption. A desorption study carried out using distilled water adjusted to pH of 2-10, suggests that ion exchange might be the mode of adsorption.
