摘要
[目的]为探明亚硝酸盐浓度、显色剂的量及测定时间三者间的关系。[方法]观测不同亚硝酸钠浓度、不同显色剂的量以及不同测定时间之间的吸光度值变化动态,并采用Excel和DPS软件对数据进行分析。[结果]结果表明,在等量显色剂条件下,随着亚硝酸钠浓度的不同,它们之间的吸光度值变化呈偏峰态趋势。[结论]该研究为测定大量水样节省了时间,同时也提高了单位时间内的工作效率。
[ Objective] The research aimed to study the relationship between the concentrations of nitrite, the dose of reagent and time for determination. [ Method] The dynamic＇ s changes of absorpiton among different concentrations of sodium nitrite, different dose of reagent and different determination time were studied..and the datas were analysized with Excel and DPS software. [ Result ] The results showed that, when the dose of reagent was constant, tile absorption changes showed the trend of partial kurtosis with different concentrations of sodium nitrite. [Conclusion] This study could save time for the deterruination of large quantity of water sample and improve the work efficiency in unit tinge.
