A new polyvinyl chloride (PVC) membrane electrode for  determining the concentration of sodium dodecylsulfate (SDS) based on  a neutral ion pair complex of dodecyltrimethylammonium-dodecylsulfate  (DTA+DS-) as ionophore is described in this paper.  The construction  and characteristic performance of the PVC membrane electrode displays  a Nernstian slope of --56.9 \pm 0.3 mV/decade in the concentration  range of 2.0 \times 10-6 to 3.2 \times 10-3 mol L-1 and a  detection limit of 1.6 \times 10-6 mol L-1.  The lifetime of the  electrode is more than 3 months without showing significant change in  the values of slope or linear concentration range.  The electrode has  wide pH range of application and short response time.  The electrode  shows selective response to DS- and poor response to common anions  except DBS-.  The electrode was used as an end point indicator  electrode for the determination of SDS content in sodium  dodecylsulfate/nonylphenol ethoxylates (SDS/NP-10) mixture solution by  potentiometric titration using Hyamine standard solution as titrant.  The maximum mol ratio (n(NP-10): n(SDS)) when SDS cannot be  determined in SDS/NP-10 mixture solution can be obtained.
