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...

Cn Systems of da Costa. SQIG-Instituto de Telecomunicações and Department of Mathematics, IST, TU Lisbon, Portugal. E-mail: [email protected]. It is well known that the paraconsistent logics Cn of da Costa fail to be algebraizable [1, 4]. Even so, an algebraic counterpart for them has been proposed in the literature, namely the class of da Costa algebras [2, 3]. Still, the connection between...

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...
