摘要
对用注射器采样甲醛法测定高浓度ＳＯ_２样气精密度、准确度、采样效率、样品的稳定性进行了研究．并应用于燃煤、燃油锅炉排气中ＳＯ_２浓度的测定。同时与碘量法测定结果进行比较和评价，表明注射器采佯甲醛法测定ＳＯ_２基本可行。
The high concentration SO2 sample was determined by the formaldehyde analysis,sampling with injector. Its precision,sampling,efficiency and stability of sample was studied. The method can be applied to determination of SO2 in exhaust of coal and oil boiler.
