Heavy metals analysisin the products of deinking flotation of digital offset prints by EDXRF spectometry
The elements of the product of deinking flotation of the digital offset print and the non printed substrate have been analyzed in this work by the EDXRF method. In the ashes of the handsheet after flotation and in the ashes of froth Pb, Zr, Sr, As, Co, Zn, Cu, Ni, Fe, Mn, Cr, V, Ti, Ca and K were analyzed. In the filtrate of the process water treated by centrifugation and coagulation as well as in filtrate of the froth treated by centrifugation Pb, Cr, Mn, Fe, Ni, Cu, Zn, an Co were analyzed. The analyzed elements of all the product originate from the components of the printing substrate, i.e. from fillers and coating. In the products of deinking flotation of digital offset print the concentrations of great majority of cations are smaller than the concentrations of in the products of deinking flotation of the non printed substrate. The polymer particles of ElectroInk glued with the particles of the coating of the printing substrate prevent releasing the cations into the process waters. Chemicals substanced do not release of cations from the particles of poymer ElectroInk.
