1. Caracterização das escórias provenientes da reciclagem de baterias de chumbo-ácido
No Brasil, a principal fonte de chumbo metalico e obtido a partir da reciclagem de baterias de chumbo-acido pelo processo pirometalurgico. O processo consiste na separacao dos componentes da bateria de chumbo-acido e posterior fusao dos metais no forno de reducao do tipo rotatorio. Esta e uma alternativa economica, sustentavel e ecologicamente correta mas, a

2. Superfosfato triplo, lama vermelha e zeólitas para remediação de metais pesados em solo contaminado / Remediation of contaminated soil with heavy metal using triple superphosphate, red mud and zeolites
Due to the heavy metal persistence in soils, the contamination by these elements is considered permanent and might result in great impact causing a degradation of the chemical and biological properties of the soil. Stabilization techniques have been used as an efficient tool for the remediation of soils that are contaminated by heavy metals, and they show al

3. Avaliação dos métodos de extração sequencial de Tessier, Keller e Miller na determinação de ferro nativo em três tipos de solos: orgânico, brunizem e latossolo
Sequential extraction is not totally effective to dissolve distinct forms of trace elements. The extractive solution, for example, can dissolve less of the target fraction and more than another not wished fraction. The goal of this work is to compare the extraction of native iron with three sequential extraction methods of the heavy metals, using three soils

4. Especiação de cobre e chumbo em sedimento do Rio Tubarão (SC) pelo método Tessier
The sequential extraction procedure proposed by Tessier and total digestion were applied for the analysis of sediment samples from Tubarão River. The recoveries were between 93.5 and 102.5% for Cu and 99.2 and 111% for Pb. The precision was tipically better than 6% for Cu and 3% for Pb. Comparison of the values obtained for the total digest with the sum of
