Development and validation of an electroanalytical methodology for determination of isoniazid and rifampicin content in pharmaceutical formulations
Tuberculosis remains a major public health problem, especially in developing countries. Brazil presents the largest number of cases in Latin America and is among the 22 countries considered priorities by the World Health Organization (WHO). The Rio de Janeiro state has the largest number of cases registered in the country. The treatment of patients, commonly, makes use of the drugs isoniazid an...
متن کاملHPLC Determination of Oxadiazon in Commercial Pesticide Formulations
Um procedimento simples, rápido e preciso de cromatografia líquida de alta eficiência (HPLC) foi desenvolvido para a determinação de oxadiazona em formulações concentradas de pesticidas emulsificáveis. 20 μL de amostra, diluída em acetronitrila, foram injetados em uma coluna Kromasil C18 (250 × 4,6 mm, 5 μm), usando acetonitrila:água (80:20) como fase móvel, numa velocidade de fluxo de 1 mL min...
متن کاملFourier Transform Infrared Determination of Imidacloprid in Pesticide Formulations
Foi desenvolvido um método simples usando Infra-Vermelho com Transformada de Fourier (IRFT) para a determinação de Imidaclopride em formulações pesticidas. As amostram foram diluídas com CHCl 3 e os espectros de IRFT de amostras e padrões foram obtidos numa resolução nominal de 4 cm, entre 4000 e 900 cm, com acumulação de 25 espectros. A determinação de Imidaclopride foi feita medindo-se tanto ...
متن کاملApplication of the electrosorption technique to remove Metribuzin pesticide.
The present work deals with the removal of Metribuzin from aqueous solutions in a batch and continuous mode using electrosorption technique. This technique is based on the combination of two processes: the adsorption of Metribuzin into activated granular carbon (GAC) column and the application of the electrochemical potential. The effects of various experimental parameters (electrochemical pote...
متن کاملEffects of soil characteristics on metribuzin dissipation using clay-gel-based formulations.
Metribuzin (MTB) is a herbicide widely used for weed control in growing soybeans and other crops and has been identified in many parts of the world as a groundwater contaminant. To prepare controlled-release formulations (CRFs) of MTB, it was entrapped within a sepiolite-gel-based matrix with one of two proportions of clay/herbicide and used as either a gel or powder after freeze-drying. To det...
