| Abstract: | A new anionic surfactant selective electrode prepared by Coating a graphite rod with PVC compound.containing triheptyl-dedecyl ammonium and dodecylbenzene sulfonate THDA-DBS is deveped.The optimum coating membrane composition is THDA-DBS 5 mg,DBP 0.4 ml,NBO.3ml and PCC 0.2 g.The electrode exhibits nernstain response to the surfactant anions over the concentration range 1×10-3 to 8.1×10-7 mol/Lwith a slope of 58 mV per decade.The detection limits are 5.6×10-7 mol/L for DBS and 7.4×10-7 mol/L fad SDS.The electrode shows high stability and selectivity,and it is easy to make and sore,and inexpensive.The electrode has been used sucCeSSfully for the determination of anionic aetergents in environmental water samples. |
