A study on the effect of the bacteria of Rhizobium phaseoli for the removal of copper ions with the method of biosorption

A Study on the Effect of the Bacteria of Rhizobium phaseoli for the Removal of Copper Ions with the Method of BiosorptionIn thıs study, two adsorptive isolates belonging to Rhizobium phaseoli and the strain adsorptive which is called as Rhizobium phaseoli CIAT 899 have been used in order to remove (Cu2+) ion from equeous from solution. In biosorption study, the effect of the initial (Cu2+) ion concentration, pH and time parameters have been examined and the capacities of biosorption values have been measured. At the end of this study, the best removal parameters and biosorption capacities have been determined to be 53.35 mg/lt, in pH 3, in 250 mg/lt concentrain, in 90th minute, in Rhizobium phaseoli 23F isolate; 31.83 mg/lt, in pH 3, in 250 mg/lt concentrain, in 90th minute, in Rhizobium phaseoli 38F isolate and 50.00 mg/lt, in pH 3, in 250 mg/lt concentrain, in 90th minute, in Rhizobium phaseoli CIAT 899 strain.Key Words: Rhizobium phaseoli, Heavy Metal, Biosorption, Cu2+
