Attention has been paid to the problem of oily water contamination. In order to meet the strict discharging requirement and obtain a high product quality, efficient separation is required. Cellulose biomass can be used in separation processes due to its good performance and low cost. Although cellulose biomass has been fabricated into hydrophobic or even superhydrophobic filter through various methods in some previous studies, the techniques about producing hydrophilic and underwater oleophobic materials are limited. The hydrophilic filter based on such natural material is also featured energy saving and anti-fouling. Coating hydrophilic nano particles onto cellulose biomass surface has the potential for developing novel filter. Therefore, this study aims to modify cellulose biomass through attaching nano particles on the biomass surface. The hydrophilic characteristics of modified biomass were analysed through the measurement of contact angle. The optimum modification conditions were determined based on factorial analysis. The modified biomass were also characterized by SEM and FTIR analyses. The modified biomass was used in oil-water separation. After modification, it was found the percentage of oil removed and the height of oil that the biomass filter could hold were enhanced. The modified biomass filter is proved to be suitable in separating water from oily water. This innovative green separation technique filter can be widely applied in future water recovery from oily wastewater.
