“…Therefore, NC13 solutions were stored in stoppered flasks with no headspace. Solutions of NC13 were standardized spectrophotometrically at 336 nm based on its newly determined (11) molar absorptivity value of 190 M™1 cm™1. The amount of NC13 formed was always less than the initial NH41 concentration due to the formation of N2 (12,13).…”

“…Note that while this illustrates the desalination process, other contaminants present in water including NOM and small organic molecules can also be rejected by RO membranes. (Farkas et al, 1949) 2.86 Â 10 5 M À1 s À1 (Gazda et al, 1995) HOI 52 M À1 s À1 (Bichsel and von Gunten, 1999) <2.0 Â 10 À2 M À1 s À1 (Bichsel and von Gunten, 1999) RO is a proven technology for the removal of an extensive range of contaminants, and this was the most effective bromide and iodide removal technique of all investigated. Importantly, this technique can remove both organic and inorganic DBP precursors simultaneously making it invaluable in DBP minimisation.…”

The presence of bromide (Br(-)) and iodide (I(-)) in source waters leads to the formation of brominated and iodinated disinfection by-products (DBPs), which are often more toxic than their chlorinated analogues. The increasing scarcity of water resources in Australia is leading to use of impaired and alternative water supplies with high bromide and iodide levels, which may result in the production of more brominated and iodinated DBPs. This review aims to provide a summary of research into bromide and iodide removal from drinking water sources. Bromide and iodide removal techniques have been broadly classified into three categories, namely; membrane, electrochemical and adsorptive techniques. Reverse osmosis, nanofiltration and electrodialysis membrane techniques are reviewed. The electrochemical techniques discussed are electrolysis, capacitive deionization and membrane capacitive deionization. Studies on bromide and iodide removal using adsorptive techniques including; layered double hydroxides, impregnated activated carbons, carbon aerogels, ion exchange resins, aluminium coagulation and soils are also assessed. Halide removal techniques have been compared, and areas for future research have been identified.
