“…A stock solution of 0.01 mol L À 1 diuron (Sigma-Aldrich, USA) was prepared in the supporting electrolyte (0.05 mol L À 1 Briton-Robinson buffer, pH 2.2) and stored under refrigeration. For pH studies, a 0.05 mol L À 1 Britton-Robinson (BR) buffer was prepared by mixing acid solutions [15] of 0.1 mol L À 1 acetic (from Vetec, Brazil), phosphoric (from Hexis Científica, Brazil), and boric (from Hexis Científica, Brazil). BR buffers in the pH range of 2.2 to 11.0 were adjusted by the addition of 1.0 mol L À 1 NaOH (from Hexis Científica, Brazil).…”

“…A contaminação de ambientes por estes metais representa um risco não apenas para a população humana, mas também para a sobrevivência de outros animais, microorganismos e plantas. O conhecimento e controle da descarga desses poluentes são, portanto, um fator importante para a proteção do meio ambiente (Martiniano, 2008;Abdel, 2007;Shazili, 2006).…”
