Rapid determination of barium ions in water using ion selective electrode

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.
