ABSTRACT

An automatic method for the determination of amylocaine and bromhexine hydrochloride by atomic absorption spectrometry (AAS) is proposed. The drugs were determined indirectly by formation of reineckates, extraction into 1,2-dichloroethane and measurement of chromium in the organic phase. The chemical conditions and experimental variables influencing the performance of the flow system of the liquid-liquid extractor were established. The proposed method allows the determination of amylocaine and bromhexine at concentrations between 3 and 120 micrograms ml-1 with a relative standard deviation of 1 and 3%, respectively, even in the presence of other synthetic drugs.
