Resumo: To evaluate the efficiency of extraction of solutions containing known amounts of potassium and sodium, porous ceramic cups were used as samplers. Solutions with increasing, decreasing and random amounts of K+ and Na+ were tested and the concentration of both cations inside and outside the samplers were analyzed. Three types of porous ceramic cups were tested and the results indicated that they reacted differently in relation to the K+ and Na+ solutions. One of them presented high adsorption capacity for the cations, therefore, not being recommended for dynamic studies of these ions. There were no differences in the behavior of the K+ and Na+ cations. The extraction of the soil solution, using porous ceramic cup samplers, needs previous evaluation under controlled conditions to determine the exactness and precision of the results

Foram testadas soluções crescentes, decrescentes e aleatórias desses cátions e analisadas as suas concentrações dentro e fora do extrator. Testes com três tipos de cápsula de cerâmica porosa mostraram que estas reagiram diferentemente em relação às soluções de K+ e Na+. Um deles apresentou alta capacidade de adsorção de cátions, não devendo, portanto, ser recomendado para estudos de dinâmica desses íons. Não houve diferenças de comportamento entre os íons K+ e Na+. A extração da solução do solo, utilizando extratores de cápsulas de cerâmica porosa, necessita de prévia avaliação desses equipamentos, em condições controladas, para que seja possível determinar a exatidão e a precisão dos resultados obtidosUniversidade Estadual de Maringá2008-05-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/285010.4025/actasciagron.v22i0.2850Acta Scientiarum.
