1. Avaliação do tratamento de lixiviado de aterro sanitário através de processo oxidativo avançado conjugado com sistema de separação por membranas
The landfill leachate is characterized by high recalcitrant organic matter concentration, ammonia and toxic compounds. This effluent can be an environmental problem due to its high pollutant potential when it is released without treatment. Studies reported in the literature showed that biological processes are not sufficient in meeting the discharge standard

2. Sistemas de análises químicas em fluxo explorando multi-impulsão, interface única ou quimiometria / Flow systems exploiting multi-pumping, single interface or chemometry
Multi-pumping flow systems (MPFS) present as an unique feature the use of solenoid pumps as fluid propelling devices, which deliver pulsed flows. This flow regime was evaluated in order to improve mixing conditions between the involved solutions, heating transfer and gas diffusion.The association of the chemometric methods of analysis and MPFS systems was de

3. DESENVOLVIMENTO DE MÉTODOS ANALÍTICOS ESPECTROLUMINESCENTES E ELETROFORÉTICOS PARA A DETERMINAÇÃO DE ALCALOIDES (BETA-CARBOLINAS, CAMPTOTECINA E DERIVADOS) DE INTERESSE FARMACOLÓGICO / DEVELOPMENT OF ANALYTICAL METHODS BASED ON LUMINESCENCE AND ELECTROPHORESIS FOR THE DETERMINATION OF ALKALOIDS (BETA-CARBOLINES, CAMPTOTHECIN AND DERIVATIVES) OF PHARMACOLOGICAL INTEREST
Analytical methods were developed for the selective determination of alkaloids of pharmacological interest. Aiming the selective determination of camptothecin (CPT) in irinotecan (CPT-11) or topotecan (TPT) based pharmaceutical formulations, two spectrofluorimetric methods and one electrophoretic method with absorciometic detection were proposed. The spectro

4. Effect of organic load, shock load, feeding time and alkalinity supplementation in an ASBBR with recirculation for cheese whey treatment / Influência da carga orgânica, da carga de choque, do tempo de alimentação e da suplementação de alcalinidade em um ASBBR com recirculação para tratamento de soro de queijo
Neste trabalho avaliou-se o desempenho de um reator anaeróbio operado em batelada seqüencial e contendo biomassa imobilizada (ASBBR) em espuma de poliuretano quando submetido a diferentes tempos de alimentação e cargas orgânicas volumétricas, além da aplicação de cargas de choque orgânicas. O reator, com mistura por recirculação da fase líquida
