采用流动注射分析法测定水氟含量是一种抛弃了稳态概念的高速分析方法,具有速度快,重现好,精度高等优点。本文利用自制的氟化物传感器和 PF-1型流动注射分析仪上测定了水氟含量。选择量为100μl,分析速度60次/小时。载液:总离子强度调节缓冲液(简称 TISAB)。实验方法;调节载液速度为1.0ml/min。由六通阀进样,进样体积为100μl。标准液浓度为0.05,0.1,0.2,0.4,1.0,2.0,4.00,6.00mg/L。结果与讨论:峰高与浓度的关系和线性范围:h 与
The determination of water fluorine content by flow injection analysis is a high-speed analytical method that abandons the concept of steady state, which has the advantages of fast speed, good reproducibility and high accuracy. In this paper, the fluorine content of water was measured by self-made fluoride sensor and PF-1 flow injection analyzer. The selected amount of 100μl, analysis speed of 60 times / hour. Carrier liquid: total ionic strength adjustment buffer (TISAB for short). Experimental method; adjust the carrier fluid speed of 1.0ml / min. Six-way valve from the injection volume of 100μl. Standard concentrations of 0.05,0.1,0.2,0.4,1.0,2.0,4.00,6.00 mg / L. Results and Discussion: Relationship between peak height and concentration and linear range: h and
