—Magnetic natural zeolite-polypyrrole composite
was prepared for removal of vanadium from aqueous solution.
The effects of initial pH, sorbent dosage, adsorption isotherms
on removal efficiency were investigated. Up to 75% removal
efficiency was obtained when the pH was 5 and the initial
vanadium concentration was 100 mg/L. The isotherm data
fitted well to the Langmuir isotherm model. The maximum
adsorption capacity determined from the Langmuir isotherm
was 57.803 mg/g at 25°C.
