碘量法是在采样前把淀粉指示剂参加碘规范溶液中,选用过程中生成硫酸根离子与碘发作反响,湿式静电除尘器使溶液由色彩变成无色,到达反响结尾。经过操控吸收液的温度和操控气体介质中二氧化硫、吸收液中碘的反响时刻(3~6min)以及采样气体流量,避免电蒸发丢失,确保丈量成果的精确性,此种办法又称为直接碘量法。别的采样器是运用直接碘量法,运用溶液吸收二氧化硫,然后加淀粉指示剂,最后由碘规范溶液滴定至蓝色结尾。该检测办法检测下限为0.01umol/mol。

碘量法检测精确度高,但操作杂乱,硫化氢等还原性物质对其测定成果影响较大,湿式静电除尘器剖析样品的时刻相对较长,不适用于接连在线监测;溶液电导率法设备费用较低,易于推行,但抗搅扰功能较差,需常常标定,长期运用易呈现差错且不易于保护;定电位电解法在湿法操作上保护办理方便,但像一切电化学传感器相同,电解传感器的输出信号跟着时刻的推移会逐渐衰降或“老化”,运用年限一般为1-2年,需求常常替换。因而,这三种检测办法均较适用于二氧化硫浓度的短期检测。而紫外荧光法具有操作简略、精度较高、抗搅扰强、剖析速度快等特色,是检测烟气中二氧化硫浓度的理想仪器,可广泛运用于电力、石油、化工、环保等具有燃煤锅炉的排污现场,能够过对污染源的排放状况进行有用的接连在线监测。
