Use of Dendrimers to Enhance Selective Separation of Boron with Nanofiltration and Reverse Osmosis Membranes

A new method to separate boron from seawater was developed. A cost effective technology based on the reaction of glycidyl ether and amine showed particular promise. Using the technology, a compound was synthesized with glycidyl hexadecyl ether and N-methyl-D-glucamine at mild conditions. The compound showed exceptionally high boron absorption. In the view of commercial application, this study also demonstrated that the boron adsorption compound could be regenerated and reused, reducing chemical costs and waste generation.
