Effect of pH on boron adsorption in some soils of Parana, Brazil

The application of increasing rates of wastewater from gelatin industry (GIW) had no effect on soil pH in CaCl 2 (Figure 1A), in all sampled layers of soil

Treatment with lower levels of BP had higher concentration of WSC resulting in lower pH values because the microorganism produced greater amounts of organic acids,

For the OM-free soil samples, the average adsorption values were 21.0, 11.0 and 28.0% lower than those obtained for the original soil samples (Table 3), of the “Xanthic”

Langmuir and Freundlich isotherms fitted well to the adsorbed data, and highest values for maximum boron adsorption were found in clayey soils, which were signifi- cantly

Glyphosate adsorption capacity by Chilean soils is high and it is related to unoccupied phosphate binding sites for the Andisol soil type. The use of different adsorption

However, the GPS was easily displaced by phosphate in the soil from Floraí, whose content of clays was low (Table 1). In the present study of the competitive

Nickel adsorption was reflected by the values of the variation in free energy ( G), whose negative sign indicated the exergonic nature of the reaction, with energy

The combined assessment of P chemical fractionation with parameters of P adsorption isotherms in the soil indicates that the indiscriminate application of phosphate fertilizers
