2. Voltametria de Pulso Diferencial (VPD) em estado sólido de manchas de Cromatografia de Camada Delgada (CCD): um novo método de análise para fitoativos antioxidantes
A new electroanalytical method coupling TLC-DPV in solid state was developed for quantitative determination of phytoantioxidants with medicinal purpose, e.g. rosmarinic acid (RA) in samples of phytopharmaceuticals, e.g. rosemary (Rosmarinus officinalis L.). The method showed to be feasible, presenting linearity in concentrations ranging from 0.694 x 10-3 to

3. Estudo da interação de íons cobre e cromo com eletrodos de pasta de carbono modificada e polianilina em meio aquoso por técnica de voltametria de pulso diferencial / Modified Carbon Paste Electrodes and Polyaniline Electrodes: Study of their interaction with copper and chromium aquous metallic ions by Differential Pulse Voltammetry
The electrochemical sensors to measure metallic ions in water and waste water are among the most important areas of research nowadays. The environmental control and monitoring chalenges that stimulated the aim of this work are tanification for industrial leather finishing and cuprous and cupric organic and inorganic fungicides. The features for characterizat

9. Electroanalytical methodology was employed aiming to study the behaviour of the triazinic pesticides Atrazine and Ametrine in water and sediment collected from the Mogi-Guaçu river. / "Utilização de metodologia eletroanalítica para estudos de adsorção de pesticidas triazínicos em amostras de sedimentos do rio Mogi-Guaçu-SP"
An electroanalytical methodology was employed aiming to study the behaviour of the triazinic pesticides Atrazine and Ametrine in water and sediment collected from the Mogi-Guaçu River. The square wave voltammetry (SWV) and the hanging mercury drop electrode (HMDE) were employed. In a first step, the experimental (and voltammetric) parameters were optimized
