| 摘 要： | 目的建立ALIANCE FUTURA水质间隔流动注射分析仪测定水源水中总氮的分析方法。方法仪器进样器自动进样,并将样品于密闭的管路中通过分析模块发生完全的化学反应后,进入流动检测池进行光度检测,由数据处理系统自动处理分析数据。结果在0～5.0 mg/L线性区间内该方法具有良好的线性关系(r=0.9999),较高的精密度和准确度(RSD=2.07%。其检出限低(0.011 mg/L),与国标法相比,差异无统计学意义(P>0.05)。结论与GB 11894-89碱性过硫酸钾消解紫外分光光度法相比,该法具有提高工作效率及结果准确性等优点,可应用于大批量常规水源水分析。

| Abstract: | Objective]To establish the method of detecting the total nitrogen in source water by using the ALIANCE FUTURA water interval flow injection analyzer. Methods]Auto-filling by the instrument sampler,the samples occurred chemical reaction completely in airtight pipeline through analyzing module,then entered flow detection pool for spectrophotometric detection.The data was processed by automatic processing system. Results]The method has good linear relationship(r=0.9999),higher precision and accuracy(RSD=2.0... |
