一种实时在线连续监测硫酸根浓度的装置及其使用方法
摘要：
一种实时在线连续监测硫酸根浓度的装置及其使用方法，本发明涉及一种实时在线连续监测硫酸根浓度的装置及其使用方法。本发明为了解决难于实现精确测量的问题。本发明装置包括氘灯、第一透镜、第一进样管路、第二进样管路、比色皿、泵、排液管路、废液池、第二透镜、光纤、光谱仪和电脑。本发明方法是利用氘灯作为紫外光源，Maya2000光谱仪作为检测器，将硫酸根溶液注入流通的比色皿中，通过测定不同浓度硫酸根溶液的OP值，给出OP值与浓度之间的定标曲线。将待测液体注入装置系统中，测定其OP值。再根据定标曲线，得到相应的硫酸根浓度，本发明提供了一种实时在线连续监测硫酸根浓度的方法。本发明应用于浓度监测领域。
摘要（英）：

The invention relates to a device for online continuously monitoring sulfate radical concentration in real time and a use method thereof. The invention aims to solve the problem of difficulty in realizing accurate measurement. The device provided by the invention comprises a deuterium lamp, a first lens, a first sampling pipeline, a second sampling pipeline, a cuvette, a pump, a liquid draining pipeline, an effluent tank, a second lens, an optical fiber, a spectrograph and a computer. According to the method provided by the invention, the deuterium lamp is used as an ultraviolet source; a Maya2000 spectrograph is used as a detector; the sulfate radical solution is injected into a flowing cuvette; a calibration curve between an OP value and concentration is given in the manner of determining the OP values of the sulfate radical solutions in different concentrations; a to-be-detected solution is injected into the device system, and then the OP value thereof is determined; a correspondingsulfate radical concentration can be acquired according to the calibration curve. The invention provides a method for online continuously monitoring sulfate radical concentration in real time. The device and the method provided by the invention can be applied to the field of concentration monitoring.
