摘　　要：本文依据传统滴定分析原理,利用流动注射装置提出一种新的自动微量滴定方法,它不仅具有流动注射滴定分析法简便快速、试剂和试样消耗少、仪器装置简单等优点,而且测定信号与被测组分的浓度直接成线性关系,结果的准确度和精度优于一般流动注射滴定方法。通过用盐酸滴定氢氧化钠进行验证,相关系数为0.9999,相对标准偏差(RSD)为0.4％。A new automatic micro-titration method is proposed based on classical titration principle and flow injection analysis instruments. The new titration method is not only simple, rapid and with consumption of small amount of reagent and sample, but also better than flow injection analysis in accuracy and precision owing to that the readout in the new titration method is linearly related to the concentration of the analyte. While the method was applied to the titration of sodium hydroxide with hydrochloric acid, a regression coefficient of 0. 9999 and a relative standard deviation of 0. 4% were obtained.
