“…The mineralogy of the Oxisols studied agrees with descriptions of various authors (Resende et al, 1980;Fontes et al, 2001;Kämpf & Curi, 2003;Weber et al, 2005).…”

“…The zero point of salt effect (ZPSE) represented the pH value at the point of intersection of the titration curves with H + and with OH -, at three KCl concentrations (0.1; 0.01 and 0.001 mol L -1 ) (Alleoni and Camargo, 1994). Samples were also investigated using the cesium (Cs + ) adsorption method, which measured the structural permanent and variable charges and was based on the preference of Cs + over Li + in the siloxane surface sites and the lower selectivity of ionizable surface group for the Cs ion (Weber et al, 2005). The BET N 2 adsorption method was used to measure the specific surface area (SSA) (Feller et al, 1992).…”

“…44 Basic cations (BC = Ca, Mg, K and Na) were extracted by ion exchange resin. Calcium and Mg contents were determined by flame atomic absorption spectrophotometry and Na and K amounts were determined by flame atomic emission spectrophotometry.…”
