摘　　要：采用定电位电解法测定固定污染源废气中SO2,根据CO标准气体干扰SO2测定的规律建立数学模型,并在实验室用CO标气对数学模型进行验证。用该数学模型对5家企业固定污染源废气中SO2监测,将测定结果与碘量法的测定结果比对,绝对误差与相对误差在允许范围内。SO2 from stational7 sources was determined using the constant potential electrolysis method. A numerical model was established according to the rule of standard CO gas interierence, and verification was clone 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.
