Abstract

PVC (polyvinyl chloride) membrane based coated wire oxalate ion selective electrode has been developed by using chitosan. The results showed the optimum composition of the membrane was chitosan: aliquat 336: PVC: DBP = 4:1:33:62 (% weight). The electrode showed Nernstian response, Nernst factor 29.90 mV/decade of concentration, linier concentration range of 1x10-5 - 1x10-1 M, detection limit of 2.56 x10-6 M, response time of 30 second, and life time of 42 days. ISE’s performance worked well in pH range of 5-7 and temperature of 25-50 oC. Validation test showed no significant difference (t test) with the SSA method so that the potentiometric method could be used as an alternative method for determining urinary oxalate.
