Boron removal by ion exchange membranes

Synthesis of hydrophilic polysulfone membranes having antifouling and boron adsorption properties via blending with an amphiphilic graft glycopolymer

“…Unfortunately, boron removal still remains a big challenge for most commercial desalination technologies due to its small molecular size, high diffusion rate and nonionic nature at normal pH range [11][12][13][14][15][16]. For example, the quality of water produced by reverse osmosis, which is a major desalination technology, in often times, fails to meet the above regulations [17][18][19][20].…”

Removal of boron from water by using reverse osmosis

“…The next two categories are adsorption [7,8] and ion-exchange processes [9][10][11][12][13]. The last category consists of membranes processes such as Donnan dialysis [14], electrodialysis [15] and reverse osmosis (RO) [16][17][18][19].…”

Transport characteristics of some carboxylic acids in the polymeric anion‐exchange membrane Neosepta‐AMH: Batch experiments

“…In all experiments, we used an anion‐exchange membrane (Neosepta‐AMH) produced by Tokuyama Soda Co., Inc. (Tokyo, Japan), whose basic properties have already been published 36, 37. It is a strongly basic membrane with NC 7 H 7 + functional groups 38. The membrane area was 62.2 cm 2 .…”
