“…Then an appropriate volume of dye stock solution was added to make the dye concentration in the range 25-100 mg/L. Reagent-grade HNO 3 and NaOH were used to adjust the suspension pH value between 2 and 11. The ion strength was adjusted by 1 mol/L NaNO 3 electrolyte solution.…”

“…Thus, the adsorption behavior of organic contaminants on natural particles has been of central interest in recent years (1)(2)(3)(4)(5). Pignatello and Xing (6) as well as Luthy et al (7) have reviewed the sorption/desorption of organic compounds on the natural particles.…”

“…This process is governed by biotic and abiotic factors (including enzymatic catalysis by microorganisms) that can cause very complex reactions involving a variety of interactions of pesticides with microorganisms that are soil constituents. The adsorption also plays a key role in the dynamics of transmission, persistence, transformation, and bioaccumulation of pesticides (Jonge et al, 1996;Gao et al, 1998). It depends on the characteristics of these compounds and the organic matter in the soil (Spark & Swift, 2002;Coquet, 2003;Ahmad et al, 2006).…”

“…O método empregado na realização do experimento de sorção foi baseado em estudos realizados por Gao et al (1998) Para realização do experimento foram utilizadas amostras coletadas em um perfil da zona não-saturada, cujas características granulométricas, valores de pH, teores de matéria orgânica e de argila se mostraram similares aos de outros perfis da área. As amostras foram secas ao ar e passadas em peneira de 2,0 mm de malha.…”

“…O herbicida apresenta baixa sorção ao solo e, tanto em superfície quanto em profundidade, a sorção diminui com a elevação do pH. Gao et al (1998) estudaram a sorção de pesticidas nos sedimentos do sul da Alemanha. Os autores notaram que a capacidade de sorção dos sedimentos é diretamente relacionada com o conteúdo de matéria orgânica e o pH.…”
