ABSTRACT
This study aimed to determine chemical and physical characteristics of the urban landed solid residue. The physical and chemical characterization of samples was obtained by analysis: specifies the mass and particle residue, pH in water (1:2.5), organic carbon, infrared spectroscopy, potentiometric titration, concentration of metals (Zn , Cd, Cu, Pb, Ni, Mg, Mn, Fe and Cr) and quantification of humic substances. The results showed that the residues presented humics substances high concentration, with groups titratable compatible with values observed in literature for humics substances; RSU_Old presented hight humification degree and high capacity of the retention of metals regarding RSU_Mature.
