Electroadsorption of Bromide from Natural Water in Granular Activated Carbon

چکیده
The adsorption and electroadsorption of bromide from natural water has been studied in a filter-press electrochemical cell using commercial granular activated carbon as the adsorbent. During experiments, different voltages were applied (2 V, 3 V 4 V) under anodic conditions. presence electric field improves capacity carbon. decrease concentration observed at high potentials (3 or may be due to transformation Br2. treatment produces higher case cathodic electroadsorption. Moreover, this electroadsorption, if system is again put open circuit conditions, no desorption produced. In following process after 24 h new consequence stage. It can concluded that effective against elimination total bromine water, with content 345 470 µg L−1, respectively, reaching values 46% single-stage bromine. application positive polarization (anodic electroadsorption) increases significantly, achieving reduction up 220 L−1 1 contact water. two stage which previous oxidation incorporated before significantly increased efficiency single step 59% stages.

متن کاملRemoval of bromide and bromate from drinking water using granular activated carbon.
Granular activated carbon (GAC) was used to remove bromide (Br⁻) and bromate (BrO(3)(-)) from drinking water in both bench- and pilot-scale experiments. The present study aims to minimize BrO(3)(-) formation and eliminate BrO(3)(-) generated during the ozonation of drinking water, particularly in packaged drinking water. Results show that the Br⁻ and BrO(3)(-) levels in GAC-treated water decrea...

study of cadmium removal from environmental water by biofilm covered granular activated carbon
the contamination of water by toxic heavy metals is a world-wide environmental problem. discharges containing cadmium, in particular, are strictly controlled due to the highly toxic nature of this element and its tendency to accumulate in the tissues of living organisms. low concentration (below 5 mg`/l) of cadmium is difficult to treat economically using chemical precipitation methodologies. i...
متن کاملBacteria associated with granular activated carbon particles in drinking water.
A sampling protocol was developed to examine particles released from granular activated carbon filter beds. A gauze filter/Swinnex procedure was used to collect carbon fines from 201 granular activated carbon-treated drinking water samples over 12 months. Application of a homogenization procedure (developed previously) indicated that 41.4% of the water samples had heterotrophic plate count bact...
