Enhancement effect of sodium dodecyl benzene sulfonate (SDBS) and its application into voltammetric determination of telmisartan.
Colloids Surf B Biointerfaces. 2007 Aug 01; 58(2):237-41.CS

Abstract

A sensitive and rapid electrochemical method was developed for the determination of telmisartan based on the enhancement effect of sodium dodecyl benzene sulfonate (SDBS). In 0.1 mol L(-1) HClO(4) and in the presence of 7.5x10(-5)mol L(-1) SDBS, a well-defined and sensitive oxidation peak was observed for telmisartan at the acetylene black (AB) paste electrode. However, the oxidation peak is poor-shaped and the peak current is very low in the absence of SDBS, suggesting that SDBS shows obvious enhancement effect for the determination of telmisartan. After all the experimental parameters were optimized, a sensitive and simple electrochemical method was developed for determining telmisartan. The oxidation peak current is proportional to the concentration of telmisartan over the range from 2.5x10(-7) to 2.0x10(-5)mol L(-1). The detection limit is 7.5x10(-8)mol L(-1) after 2 min of accumulation. This new voltammetric method was successfully used to detect telmisartan in drugs.
