| description | The construction and
characteristic performance of PVC membrane
electrode responsive to sodium dodecylsulfate
(SDS) are described in this paper. The electrode
is based on hexadecyl trimethyl ammonium
bromide-Sodium dodecylsulfate (CTA+DS−) ion pair as ionophore in PVC membrane, which displays a Nernstian slope of −58 ± 0.9 mV/decade in a 5.0 × 10−6 to 2.5 × 10−3 mol L−1 concentration range and a limit of detection of 2.9 × 10−6 mol L−1. The electrode can be used for 3 months without showing significant changes in the value of slope or working range. Also the electrode has wide pH range of application and short response time. The electrode shows a selective response to SDS and a poor response to common inorganic anions. The selective sequence found was SDS > HCO3 − > CH3COO− > Cl− > I− > NO3 −≈ Br− > F− > CO3 2− > C6H5O7 3− > C2O4 2− > SO4 2− > C4H4O6 2− > SO3 2− > PO4 3−. The potentiometric selectivity coefficients
determined are indicating that common anions would not interfere
in the SDS determination. The electrode has been utilized as an
end point indicator electrode for potentiometric titration
involving hyamine as titrant. |
