dc.description.abstract基于碱性水溶液中臭氧氧化鲁米诺产生化学发光的现象,建立了利用流动注射化学发光技术检测水体溶解臭氧(DO3 )的方法。检测了较高和较低两部分的DO3 浓度范围,低浓度DO3 从20μg/L到65μg/L,工作曲线为y=27. 658In(X) -192. 75;检出限为8. 5μg/L( 7次空白信号检测);高浓度DO3 从0 089mg/L到0. 890mg/L,线性关系为y=0.0018x-23. 711。溶液中的DO3 由靛蓝二磺酸钠法确定。随后利用化学发光系统检测鼓入臭氧气体的自来水,由工作曲线可以确定自来水中DO3 的量。方法简便,结果准确。
dc.description.abstractUtilizing the phenomenon that himinol can be oxidized by the dissolved ozone to produce luminescence and a new method of using chemiluminescence to determine the concentration of ozone in aqueous was established in this study. Ozoue generated by an ozonator dissolved in distilled water by bubbling, which was diluted to different concentration ozone solutions by FI system. The CL emission result was directly proportional to the concentration of ozone in solution. The work curve of y=27.658Ln(X)-192.75 was acquired for the concentration range of ozone from 20 μg/L to 65 μg/L and the detection limit was 8.5 μg/L. Another work curve of y=0.0018x-23.711 was also acquired for the high concentration of ozone from 0.089 mg/L to 0.890 mg/L. The concentration of ozone was measured by indigo method. An ozonated drinking water sample was analyzed through FIA-CL method. It shows that the result is credible and the method is convenient .
