Determination of Characteristics of Urban Solid Waste in Landfill

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.
