1. SELECTIVE DETERMINATION OF FLUORQUINOLONES FOR CELLULOSE SURFACE ROOMTEMPERATURE PHOSPHORIMETRY WHITH THORIUM NITRATE / DETERMINAÇÃO SELETIVA DE FLUOROQUINOLONAS POR FOSFORIMETRIA NA TEMPERATURA AMBIENTE SUPORTADA EM SUBSTRATO DE CELULOSE COM NITRATO DE TÓRIO
In this work, analytical methods based on solid surface room-temperature phosphorimetry were developed aiming the selective determination of fluorquinolones. More spectilly, thorium nitrate was evaluated as phosphorescence inducer aiming the sequential determination of norfloxacin (NOR) and levofloxacin (LEV), selective determination of NOR in presence of ci

2. Estudo de modificadores quimicos e superficies modificadas para a determinação de estanho por espectrometria de absorção atomica com forno de grafite
Tin is an important element from an environmental viewpoint and is essential for humans at trace levels. However, the direct determination of tin by graphite furnace AAS has been fraught with problems such as volatilization loss, interaction with the graphite surface and sample matrix interference. In the present work, the use of the calcium, barium and stro
