“…The increase in environmental pollution caused by toxic metals is of great concern because of their carcinogenic properties, non-biodegradability and bio-accumulation. Copper ions are non-biodegradable toxic heavy metals and acute poisoning of Cu(II) causes headache [1]. The major sources of copper contamination to water comes from industrial process such as electroplating, battery and accumulator manufacturing, and porcelain enameling [2].…”

Present study deals with the evaluation of biosorptive removal of copper byFlavobacterium sp.Experiments have been carried out to find the effect of various parameters such as initial pH, contact time and initial metal ion concentration. Adsorption equilibrium studies showed that Cu(II) adsorption data followed the Langmuir model, the maximum binding capacity ofwas 55.20 mg/g at pH 6.0. Kinetics of copper biosorption by Flavobacterium sp. biomass is better described by pseudo second order kinetic model. It was also clearly observed that The present study indicated thatFlavobacterium sp.biomass may be used as a cost and effective biosorbent for the removal of Cu(II) ions from wastewater.

Present study deals with the evaluation of biosorptive removal of nickel byFlavobacterium sp.Experiments have been carried out to find the effect of various parameters such as initial pH, contact time and initial metal ion concentration. Adsorption equilibrium studies showed that Ni(II) adsorption data followed the Langmuir model, the maximum binding capacity of Ni(II) was 64.20 mg/g at pH 7.0. Kinetics of nickel biosorption by Flavobacterium sp.biomass is better described by pseudo second order kinetic model. The equilibrium isotherm data are very well represented by Langmuir isotherm equation, which confirmed the monolayer coverage of nickel onto Flavobacterium sp.biomass. It was also clearly observed that The present study indicated thatFlavobacterium sp.biomass may be used as an inexpensive and effective biosorbent for the removal of Ni(II) ions from environmental wastewater.

The Ni(II) biosorption characteristics of Pseudomonas fluorescens biomass was examined as a function of initial pH, contact time and initial metal ion concentration. The pseudo-second-order kinetic model was found to be well suited for the entire adsorption process of Ni(II) on biomass. Adsorption equilibrium studies showed that Ni(II) adsorption data followed the Langmuir model, the maximum binding capacity of Ni(II) was 84.45 mg/g at pH 7.0 , shaker speed 150 rpm, at 27 °C. FTIR spectra showed that the principal functional sites taking part in the sorption process included carboxyl , hydroxyl groups and -CH3 stretching groups, the mechanism analysis showed that the chemical chelating was the main adsorption form, electrostatic attraction hydrogen bonding in the process of adsorption. The present study indicated that Pseudomonas fluorescens biomass may be used as an inexpensive, effective and easily cultivable biosorbent for the removal of Ni(II) ions from environmental and industrial wastewater.
