摘要：
A method for the determination of bentazepam by the oxidation wave which originates from the 1 N, using a 50% C18 carbon paste electrode is described. A pre-concentration cell at open circuit and a measuring cell have been used. The electroanalytical technique employed was the differential pulse voltammetry. The interferences with different psychotropic drugs have been applied to the determination of bentazepam directly in urine and with previous extraction in ethyl ether.
