摘　　要：因吸收液相对偏多,采气量偏少,过滤液偏少,最后参加显色反应的气体量很少,实验现象是显色溶液全部无色;如果减少吸收液,增加采气量,增加过滤液,使参加显色反应的气体增加很多,这样分析才科学、合理。Because of comparatively less absorbing liquid, less sampled gas and less filtered liquid, volume of gas took part in color reaction at last is very little, colored solution for experiment appearance is finally non-color. If we reduce absorbing liquid, add sampled gas and filtered liquid, volume of gas been able to take part in color reaction will be more, thus the analysis result is reasonable.

关 键 词：吸收液 采气 过滤液 增加 减少
