development of an immobilized enzyme electrode for the determination of sulfite ion
نویسندگان
چکیده
an enzyme electrode was developed using the enzyme sulfite oxidase (ec1.8.3.1) immobilized onto pig intestine. hydrogen peroxide produced was monitored amperometrically. all experimental parameters such as ph, temperature, buffer constituent concentration, were thoroughly investigated and optimized when appropriate. the response to sulfite concentration was linear in the range 5.2´10-6 to 1.02´10-3 m. the proposed method was found to have a correlation coefficient of 0.952 when evaluated in comparison with the standard titration method.

متن کاملAn electrode immobilized in a graphite matrix with ion pair complex for the determination of diclofenac in pharmaceuticals
A simple, precise, rapid and low-cost potentiometric method for diclofenac determination in pharmaceuticals is proposed. A new diclofenac-sensitive electrode was constructed by incorporating the diclofenac ion pair complex with butyl rhodamine B into graphite matrix. The electrode exhibited a linear response over the concentration range of 1 × 10-4 – 5 × 10-2 mol L-1, a detection limit of 3.9×1...
