• [Display omitted] •An innovative method was designed with combination of chitosan beads and Lemna gibba.•We achieved 50% of total boron (B) removal from drinking water.•Maximum B sorption capacity was found as 3.9mg/g (8mgL−1) for a plant-based chitosan composite.•Highest B uptake from drinking water by Lemna gibba was determined as 2242mgkg−1.•The method could be promising for B removal from drinking water. Boron exists in various types of water environments, and it is difficult and costly to remove B with conventional treatment methods from drinking water. Clearly, alternative and cost effective treatment techniques are imperative. In the present study, an innovative and environment friendly method based on hybrid systems consisting of various chitosan composite beads and Lemna gibba were evaluated for removal of B from drinking water. Our results from batch adsorption experiment indicated that a plant-based chitosan composite bead has a higher capacity of B removal than mineral-based chitosan composite beads. Almost 50% of total B removal was achieved using the hybrid system based on dried Lemna-chitosan composite beads and Lemna gibba combination in 4 days. Even at the high B concentration (8mgBL−1), B in drinking water could be reduced to less than 2.4mgL −1 when 0.05g plant-based chitosan composite beads and 12 Lemna fronds were used for 50mL test solution.
