| Abstract: | SO2 from stationary sources was determined using the constant potential electrolysis method. A numerical model was established according to the rule of standard CO gas interference, and verification was done in the laboratory through preparation of CO standard gases. The numerical model was applied to monitor SO2 from five enterprises' stationary sources. The absolute error and relative error between the current method and the iodine titration method were within the acceptance scope. |
