Adsorption of Nickel by Disposed Sludge of Wastewater Treatment Unit of Kaveh Industrial City Ansareh salehi asalehi iut@yahoo com December 30 2012 Department of natural resources Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc language Farsi Supervisor Norolah mirghaffari mnorolah@cc iut ac ir Abstract Shortage of freshwater is a global problem and polluting resource was intensified this problem Discharge of industrial wastewater is an important source of pollution Heavy metals in industrial wastewater are one of the most dangerous environmental pollutants Various chemical and physical methods such as coagulation sedimentation and reverse osmosis have been used to remove heavy metals from industrial wastewater Adsorption process is relatively an inexpensive technique that has taken more attention in recent years Different adsorbent are used for removal of heavy metal from industrial wastewater Disposed sludge of wastewater treatment plant is an available and a low cost adsorbent In this study the biomass of disposed sludge of wastewater treatment unit of Kaveh industrial city was used as an adsorbent for sorption of nickel Some of morphological and chemical properties of adsorbent were determined by scanning electron microscopy SEM energy dispersive X ray EDX Fourier transform infrared spectroscopy FT IR and inductively coupled plasma ICP Adsorption experiments were carried out using batch and column techniques and the parameters affecting the sorption including equilibrium time pH initial nickel concentration and adsorbent amount were investigated Adsorption kinetics studies showed that the adsorption of nickel by disposed sludge biomass was relatively fast The kinetics data for nickel sorption by disposed sludge biomass were precisely described by pseudo second order model The optimum pH was at 5 The suitability of the Langmuir Freundlich and Redlich Peterson adsorption models to the data was indicated nickel adsorbed on disposed sludge biomass was fitted well to Redlich Peterson model Maximum capacity of nickel adsorption was 14 75 mg g Maximum nickel desorption was 65 which occurred using nitric acid The increase of adsorbent amount increased the nickel sorption percentage The performance of disposed sludge biomass for removal of nickel from an industrial wastewater was 35 Key words Nickel Adsorption Disposed sludge biomass Adsorption kinetic Adsorption isotherm
