“…For this hypothesis to be tested, a specific protocol of sample preparation, scanning, and data processing would have to be carried out. The lack of exchangeable Al 3+ , resulting mainly from the high pH, implies small Al 3+ activity and unsuitable condition to the deposition of Al-hydroxy into the 2:1 interlayers and the formation of hydroxy-interlayered smectite (HIS), which would be an even more complex mineral (Barnhisel and Bertsch, 1989;Sartor and Azevedo, 2014). This explains the high cation-exchange capacity of Fluvisol (Table 4) despite its low clay content (300 g kg -1 ) ( Table 3).…”

“…A pilarização causa mudanças significativas nas argilas, tais como aumento da acidez superficial, da distância basal, da área superficial específica, do volume de microporos e da estabilidade térmica, potencializando suas características adsortivas e catalíticas. A intensidade dessas mudanças é dependente do método de síntese e da argila utilizada (SARTOR; AZEVEDO, 2014). Essas mudanças permitem diversas aplicações ambientais e agronômicas e a seguir serão relatados algumas dessas aplicações práticas.…”
