摘要
目的探讨麝香草酚分光光度法在测定水中硝酸盐氮的实用性。方法利用人分光光度计,对麝香草酚分光光度法在水中硝酸盐氮测定方面的原理,试剂,实验步骤及容易出现的问题进行试验,通过加标回收率的测定,证明本方法的可靠性。结果该方法有良好的准确度和灵敏度,回收率在99.7%-100.5%之间,工作曲线在0-10ug之间,线性极好(r=0.9998)。结论该方法操作简易、快速、灵敏度好,没有样品损失,适用于水中硝酸盐氮的测定。
Objective To study the application of thymol spectrophotometry method in oxidized nitrate nitrogen in water. Methods Spectrophotometry was applied to test the principle ,reagent,experimental procedure and problems in oxidized nitrate in water with thymol methodo And the reliability of this method is proved by labeling the rate of recovery. Results This method is accurate and sensitive with recovery rate of 99.7%-100.5%.Function curve is between 0 ug to 10 ug. Linearity is wonderful （r=0.9998）. Conclusion this method is simple in operation, and high sensitivity,with less losen of simple,It is applicable in oxidized nitrate nitrogen in water.
