MACHUA VEITIA, Mercedes et al. Determinación espectrofotométrica de un producto activo zeolítico en materia prima y tabletas vaginales. Rev Cubana Farm [online]. 1999, vol.33, n.3, pp.177-182. ISSN 0034-7515.

The use of active zeolitic products as drugs of specific action requires the development of analytical techniques to control the quality of the finished product. A spectrophotometric method of analysis was validated for a zinc?activated zeolite (PAZ-ZZ), starting from the reaction with zincum. The lineality, precision, exactitude and specificity of the proposed method were evaluated. This technique was later applied to the analysis of PAZ-ZZ raw material and vaginal tablets containing this active principle. The results were compared with those obtained for atomic absortion spectroscopy.
