BIOSORPTION EFFICACY OF ISOLATED BACTERIAL STRAIN FOR NICKEL REMOVAL FROM SYNTHETIC SOLUTIONSIMMI GOEL AND PARMINDER KAURAbstract In the present research work, nickel tolerant bacterial colonies were isolated and used for biosorption of nickel from synthetic solution at optimized parameters. The results revealed that maximum biosorption of Ni(II) is 60.3% for an optimum concentration of 30 ppm at a contact time 20 hours, pH 4, temperature 25!,dextrose concentration 0.8 g/100 mL and inoculum dosage 4 mL/100 mL of solution. These indicated that the bacterial isolate can be used efficiently in the removal of nickel from synthetic solution. |
