摘要
【目的】对水杨基荧光酮分光光度法(A法)与石墨炉原子吸收法(B法)测定饮用水中钛进行比较,从而建立一种简便、快速、高灵敏度的测定饮用水中钛的方法。【方法】水杨基荧光酮分光光度法按照GB/T5750.6-2006《生活饮用水标准检验方法-金属指标》17.2的有关规定进行。石墨炉原子吸收法按照仪器厂家推荐条件进行。【结果】两种方法均具有良好的线性关系、准确度和精密度,所测得的结果在统计学上无显著性差异。【结论】A法干扰因素多,操作繁琐。B法则操作简单,灵敏度高,精密度和准确度均符合分析要求,适宜推广应用。
[Objective]To establish a simple,rapid,highly sensitive method for determination of titanium in drinking water by comparing Salieylfluorone Spectrophotometry(Method A) and Graphite Furnace Atomic Absorption Spectrophotometry(Method B).[ Methods] According to the relevant provisions of 17.2 in "test methods for drinking water-metal targets"(GB/T5750.6-2006),the salicylfluorone spectrophotometry was used.Graphite furnace atomic absorption spectrometry was used according to the conditions recommended by equipment manufacturers.[ Results]Two methods have good correlation,accuracy and precision,moreover,the measured results showed no significant difference.[Conclusion] Method A has more disturbances and it is complicated.Method B is simple and high sensitive.The precision and accuracy are in line with the requirements,so it is suitable for application.
