摘要

本文介绍了用BW-Tek型紫外/可见分光光度计在线测量超声雾化过程中异丙醇浓度的初步结果。建立了带雾化容器的实验装置，并用探针进行了在线测量。使用异丙醇和水的标准混合物进行测试，异丙醇的体积浓度在19%至83%之间。用固定式分光光度计和气相色谱法对在线分光光度计法的结果进行了验证。对所获得的数据进行线性校准，并以置信区间评估所测试方法的测量不确定度。

On-line spectrophotometric measurements of isopropanol concentration in process of nebulization

The paper presents preliminary results for online measurement method of isopropanol concentration in the ultrasonic nebulization process using BW-Tek compact UV/Vis spectrophotometer. The experimental setup with nebulization vessel was constructed with a probe for on-line measurements. The tests were performed using a standard mixture of isopropanol and water with the volume isopropanol concentration in the range 19% to 83%. The results of on-line spectrophotometric method were verified using stationary spectrophotometer and a gas chromatography method. Linear calibration for the obtained data was performed and measurement uncertainties for the tested method were evaluated as confidence intervals.
