Abstract

The mechanisms of the arsenite acid scavenging bromine and [Fe(Phen₃)]³⁺ reaction were studied by the electrochemical methods. The arsenite acid scavenging bromine and [Fe(Phen₃)]³⁺ reaction rate constants in sulfuric acid in the range of 23 ℃ to 69 ℃ and in the range of 19 ℃ to 69 ℃ were determined by measuring the steady state limiting current, respectively. The activation energy of the arsenite acid scavenging bromine reaction in sulfuric acid is 33 kJ·mol^-1.
