“…Similar results were reported by Matos et al, (1996); Fontes et al, (2000); Gomes et al, (2001); Alumaa et al, (2001) and Silveira and Alleoni (2003) for highly-weathered tropical soils.…”

“…Both non-competitive and competitive solutions were prepared and mixed with 2 g of the ADFE. Nitrate was chosen as the supporting electrolyte because it has a small capacity to complex metallic cations (Msaky and Calvet, 1990;Silveira et al, 2003). Concentrations were standardized by molar concentrations, suppressing the mass effect difference among the metal ions (Table 1) (Echeverría et al, 1998).…”

“…Alguns autores recomendam a agitação por 24 horas para garantir o estabelecimento do equilíbrio de adsorção (PETRUZELLI et al, 1985). Na maioria dos trabalhos de adsorção em solos tropicais publicados, constata-se que se tem utilizado este tempo de agitação (SOARES, 2004;MELLIS et al, 2004;SILVEIRA et al 2003, DIAS et al, 2001CASAGRANDE et al 2004;ALLEONI, et al, 2005;VEGA et al, 2006). Porém, nos últimos anos, alguns autores adotaram o tempo de agitação de 1 hora para se estudar a adsorção de metais em solos tropicais (MOREIRA, 2004;FONTES e Gomes, 2003).…”

“…Na Floresta do Palmito, a C/N é muito maior (58,7), o que torna a decomposição mais lenta. Além disso, deve-se considerar também a acidez dos sítios de coleta, ambos ácidos, que também interferem no processo de adsorção do Cu (Silveira & Alleoni 2003). ), sódio (Na, g kg -1…”
