Recycling wastepaper with flexographic newspaper is a challenge for conventional flotation deinking. Flexographic inks are made of water-soluble, highly dispersible acrylic resin binder. A constituent of these inks are submicron carbon black particles which are hydrophilic. The nature of flexographic inks makes it difficult for deinking by traditional flotation mechanism. The use of sodium sulfite for deinking oil-based newsprint at neutral pH was reported as effective in deinking as a conventional alkaline process, but at a reduced chemical consumption and cost. This study focuses on the use sulfite for deinking flexographic newsprint. Moreover, a promising technology which uses direct electric field incorporated into flotation is studied together with the use of sodium sulfite at neutral pH. The effect of the deinking process on pulp optical properties was examined. Deinking under neutral pH, show improvement in brightness, and in residue ink concentration as compared with conventional alkaline deinking. The ink particle removal process assisted with electric field is modelled in similar form as electroflotation in mineral processing
