Sažetak
The conventional and the most used process in paper recycling is deinking flotation. The separation criterion in the process is based on different wetting of the surface of ink particles, fillers, coating pigments, binders (hydrophobic ones) which adhere to the air bubbles and detach in the form of froth in relation to the cellulose fibers (hydrophilic ones) which stay in suspension. In order to achieve the described surface properties, it is possible to use the whole series of chemical which include liquid fatty acids, soaps, synthetic surfactants which can be non-ionic, cationic and anionic ones. The influence of the surfactants of different chemical composition on some optical properties and the size distribution of the residual particles on lab handsheets in different phases of the recycling process of offset prints are presented in this article.
