Abstract

Barium, an alkaline earth metal have been determined by numerous sophisticated analytical tools that are quite expensive and often involve sample pre-treatment. Present research manuscript is focused on a novel method for the determination of barium ions in water samples by employing a graphite electrode coated with barium selective membrane. The developed electrode with membrane composition of 33.0% polyvinyl chloride, 57.0% ortho nitro phenyl octyl ether, 6.0% sodium tetraphenyl borate, 2.0% multiwalled nanotube and 2.0% ionophore dibenzo 24 crown 8 was used and the results obtained were compared by ICP-AES method.
