“…Usually four to five renewals were needed for obtaining constant membrane potential values. Some of the membrane preparations exhibited potential even when solutions of equal concentrations were kept on either side of the membrane [11]. Such asymmetric membranes were discarded and studies were only carried out with well behaved samples.…”

“…These surfactants have an inherent tendency to accumulate at interfaces depending upon the nature of the interface and that of the surfactants. Accordingly, the properties which depend on the interfacial character of a system exhibit alteration in the presence of such surfactants [7][8][9]. Therefore the surfactants are frequently used in a variety of textile technology and biotechnology.…”

Sodium alpha olefin sulfonate, an anionic surfactant was modified in carbon paste electrode by immobilization technique. The surfactant modified carbon paste electrode (SAOS/MCPE) was applied for the electrochemical determination of dopamine. The modified electrode shows excellent electrocatalytic property towards DA at pH 7.2 in Phosphate Buffer solution (PBS). The effects of scan rate and concentration of dopamine was studied and the electrode process was adsorptioncontrolled processes. The modified electrode resolves the well-defined two peaks for dopamine and ascorbic acid which is absent for bare carbon paste electrode and simultaneous studies was studied by cyclic and differential pulse voltammetric techniques. The detection limit was found to be 1.051 × 10 -6 M respectively and the modified electrode shows good sensitivity and selectivity for dopamine.

“…CA is also used in the preparation of microchip for on column as CA-coupler [46]. Singh [47] modified CA membrane with surfactant (sodium dodecyl sulfate), then the membrane exhibits good cation selectivity. Ju [48] and Marken [49] prepared porous composite films of CA/TiO 2 nanoparticles and CA/nanogold which promoted the detection of methemoglobin and antigen.…”

The cellulose acetate covered Prussian blue modified glassy carbon electrode (GCE/PB/CA) was fabricated as a novel hydrogen peroxide sensor. It was shown by scanning electron microscope (SEM) and atomic force microscope (AFM) that Prussian blue was covered and protected by cellulose acetate perfectly. The modified electrode showed a good electrocatalytic activity for H 2 O 2 reduction in neutral aqueous solution. H 2 O 2 was detected amperometrically in 0.05 mol/L phosphate buffer solutions (pH 7.0, containing 0.1 mol/L KCl as supporting electrolyte) at an applied potential of À 0.2 V (vs. SCE). The response current was proportional to the concentration of H 2 O 2 in the range of 1.0 Â 10 À5 mol/L to 2.5 Â 10 À4 mol/L with the detection limit of 2.2 Â 10 À6 mol/L at a signal to noise ratio 3.
