摘要：
The electrochemical response of Bromothymol blue at carbon paste electrode in presence of 0.1M KCl was investigated by the cyclic voltammetric technique. It showed a well-defined oxidation peak at 0.73V and a sensitive reduction peaks at 0.34 V. The effect of concentration and scan rate of Bromothymol blue was studied. The scan rate effect showed the electrode process is adsorption-controlled. The effect of surfactants like Sodium Dodecyl Sulfate (SDS), Cetyltrimethylammonium Bromide (CTAB), and TritonX-100 (TX-100) were studied by immobilizing method. Among these SDS was showed excellent enhancement in both oxidation peak and reduction peak currents. The concentration effect of the SDS surfactant was studied.
