Humic substances of residues from industrial sugarcane processing: complexation study

摘要

The study the complexation of humic substances from filter cake (residues from Brazilian industrial sugarcane processing) with Cu~(2+) , Cd~(2+) , Cr ~(3+) , Ni ~(2+) and Pb~(2+) by tangential ultrafiltration system was evaluated. By the results (Table 1) can be described by the following order of increasing affinity of HS from FC by metals: HSFC_(AL) – Cr ~(3+)
