Clotrimazol é reduzido em eletrodo de mercúrio em tampão fosfato pH > 6 através de um processo reversível de um elétron. O processo eletródico apresenta forte efeito de adsorção, o qual pode ser minimizado na presença de Triton X-100. Clotrimazol pode ser determinado em níveis de 50 ng mL-1 quando pré-acumulado durante 3 min à –0,20 V. O método proposto foi aplicado para determinação do fármaco...

A thermoanalyical study of pure atenolol and a commercial tablets containinf the drug were carried out using thermogravimetric (TG) and differencial scanning calorimetry (DSC) techniques. Nonisothermal method was employed to determine kinetics data of decomposition process. In order to evaluate interaction observed in the commercial tablets, compatibility studies of drug and excipients (microcr...

On a question of Pereira

Answering a question of Pereira we show that it is possible to have a model violating the Singular Cardinal Hypothesis without a tree-like continuous scale.
