Remediation of bromate-contaminated groundwater in an ex situ fixed-film bioreactor

Enhanced removal efficiency of bromate from aqueous solutions by nanoscale zero-valent iron immobilized on activated carbon

“…After that, 0.9598 g AC was immersed in 60 mL ethanol/deionized water mixture (V/V 4:1) which has dissolved 1.1912 g FeSO 4 ·7H 2 O, 2 C. Xu et al / Desalination and Water Treatment and then the suspension liquid was stirred for at least 30 min. The following steps are the same with those described above.…”

“…It has been classified as a possible carcinogenic substance to humans by both the United States Environmental Protection Agency and the World Health Organization (WHO) [1,2]. BrO À 3 can enter the human body by oral route and the enforceable maximum contaminant level is 10 μg/L [3].…”

Synthesis, characterization, and application of Fe-CNTs nanocomposite for BrO3− remediation from water samples

“…Eelectrochemical oxidation [9], reduction by zero-valent iron (Fe 0 ) [10], biofiltration [11], ion-exchange [12], reverse osmosis [13] nano-filtration [14], catalytic hydrogenation over the Pd/Al 2 O 3 catalyst [15] have been reported for the abatement of BrO 3 À from aqueous solutions. However, these techniques have certain shortcomings, generation of toxic by-products during electrochemical oxidation and high operational cost for nano-filtration and reverse osmosis limits their scale up application.…”

Fe–Al layered double hydroxides in bromate reduction: Synthesis and reactivity

“…Interest in bromate as a possible carcinogen has engendered several studies of the removal of bromate in water using activated carbon [9][10][11][12], biologically activated carbon [13], bioreactors [14,15], activated carbon felt electrodes [16], zero-valent iron [17,18], and akaganéite (b-FeOOH) [19,20]. Recently, Hajizadeh et al [21] studied bromate removal using chitosan-based molecularly imprinted polymer (MIP) and inorganic adsorbent (Fe 2 O 3 ÁAl 2 O 3 ÁxH 2 O).…”
