摘要: The effects of sonication activated sludge on heavy metal uptake were in a first time investigated respect with potential modifications floc surface properties. treatment led to the simultaneous increase specific area and availability negative and/or hydrophilic sites. In parallel, organic matter was released soluble fraction. Sorption isotherms cadmium copper showed that characteristics mechanisms highly dependent both species energy supplied. fixation sites Cd(II) uptake. For Cu(II), phase during seemed act as ligand limit adsorption flocs surface. Three different metals have been identified: proton exchange, ion exchange (co)precipitation.
