Despite surfactant-based ink removal being extensively investigated, the best quality deinked pulp obtained by flotation deinking exhibits effective residual ink concentration (ERIC) and brightness values that are consistently lower than expected. To understand this, the effect of oxygen and nitrogen bubbling on the behavior of a commercial surfactant and the fatty acid of Morindacitrifolia L. (FAMC) was investigated in this study. Oxidation was found to enable binding between the surfactant / FAMC and the ink components and enhance flotation deinking. The hydrophilic properties of the surfactant also enable the surfactant and FAMC molecules to physically contact or interact with ink components.
