چکیده انگلیسی
One of the problems of BrO3â detection using the electrochemical method, such as a cyclic voltammetry (CV) is that it is impressionable to interferences from Humic acid (HA). The objective of this study was to determine the effect of HA on electrochemical detection of BrO3â using metalloporphyrin-based multilayer sensor under different pH conditions in the presence of FeCl3. The effect of HA interference on chemical interaction at the electrode surface in the presence of FeCl3 was determined based on Fourier transform infrared spectrum. CV was used to measure the concentration of BrO3â in the solution containing HA with or without different concentrations of FeCl3. Results of CV revealed a dynamic linear concentration range of BrO3â from 10 to 100â¯Î¼g/L in 0.1 to 1â¯mg/L of HA solution (pH 9). The detection limit for BrO3â concentration was 8.9â¯Î¼g/L in 0.1â¯mg/L of HA solution.
