10.22376/ijpbs.2019.10.1.p1-12 Volume 5 Issue 1 2014 (January - March) High oxygen evolution overpotential and inexpensive Ti/Co lessThan sub greaterThan 3 lessThan /sub greaterThan O lessThan sub greaterThan 4 lessThan /sub greaterThan /PbO lessThan sub greaterThan 2 lessThan /sub greaterThan /(SnO lessThan sub greaterThan 2 lessThan /sub greaterThan +Sb lessThan sub greaterThan 2 lessThan /sub greaterThan O lessThan sub greaterThan 3 lessThan /sub greaterThan ) and (Ti/(SnO lessThan sub greaterThan 2 lessThan /sub greaterThan +Sb lessThan sub greaterThan 2 lessThan /sub greaterThan O lessThan sub greaterThan 3 lessThan /sub greaterThan ) electrodes were investigated in this work. These electrodes were prepared and used as anodes for removal of Reactive Black 5 (RB5) dye in aqueous solution. In some local cases in Palestine, wastewater color was found to be the only problem in meeting local effluent standards. This investigation reveals that both electrodes can remove the color of these dyes completely. After 10 min, nearly complete degradation of RB5 was achieved (99.2%, and 91.90) using Ti/Co lessThan sub greaterThan 3 lessThan /sub greaterThan O lessThan sub greaterThan 4 lessThan /sub greaterThan /PbO lessThan sub greaterThan 2 lessThan /sub greaterThan /(SnO lessThan sub greaterThan 2 lessThan /sub greaterThan +Sb lessThan sub greaterThan 2 lessThan /sub greaterThan O lessThan sub greaterThan 3 lessThan /sub greaterThan ) and (Ti/(SnO lessThan sub greaterThan 2 lessThan /sub greaterThan +Sb lessThan sub greaterThan 2 lessThan /sub greaterThan O lessThan sub greaterThan 3 lessThan /sub greaterThan ) electrodes respectively at pH 6.8, current density 30 mA cm lessThan sup greaterThan -2 lessThan /sup greaterThan and in the presence of NaCl (4 g L lessThan sup greaterThan -1 lessThan /sup greaterThan ) at 25 lessThan sup greaterThan o lessThan /sup greaterThan C. At the same condition the optimal time for COD removal for Ti/Co lessThan sub greaterThan 3 lessThan /sub greaterThan O lessThan sub greaterThan 4 lessThan /sub greaterThan /PbO lessThan sub greaterThan 2 lessThan /sub greaterThan /(SnO lessThan sub greaterThan 2 lessThan /sub greaterThan +Sb lessThan sub greaterThan 2 lessThan /sub greaterThan O lessThan sub greaterThan 3 lessThan /sub greaterThan ) and Ti/(SnO lessThan sub greaterThan 2 lessThan /sub greaterThan +Sb lessThan sub greaterThan 2 lessThan /sub greaterThan O lessThan sub greaterThan 3 lessThan /sub greaterThan electrodes was 7 and 9 hours.
