Embodiment Construction

[0043] see figure 1 , figure 2 with image 3 ,

[0044] Utilize the ozone oxidation kinetic parameter analysis system, carry out according to the following steps:

[0045] (1). Utilize an ozone generator to generate ozone, and at a flow rate of 100-200ml / min, pass through the gas disperser 7 of the ozone solution preparation chamber 8, adopt porous material-Teflon, mix it into the distilled water 9, and continuously feed the ozone After 10 minutes, an ozone solution with an ozone concentration of about 0.2mmol / L was obtained, and the feeding was stopped;

[0046] (2). In order to ensure that ozone is a limited reactant, the concentration of organic matter should be 3-5 times greater than the concentration of ozone solution;

[0047] (3). The ozone solution and the organic matter solution are injected into the reaction chamber 4 by quantitative injectors 5 and 12 at the same time, so as to reduce the dead volume;

[0048] (4). In order to ensure the detection accuracy of ...

Abstract

A method of utilizing chemiluminescence dynamic curve to analyze dynamic parameter of ozone oxidizing reaction uses relation of light signal intensity I to time T to confirm reaction grade and reaction rate constant.

Description

technical field [0001] The invention belongs to the technical field of environmental chemical monitoring, and specifically uses the ozone oxidation chemiluminescence kinetic curve to analyze the kinetic parameters of the ozone oxidation reaction, and the kinetic parameters include the reaction rate constant and the reaction order. Background technique [0002] As a strong oxidant, ozone is widely used in the process of degrading organic pollutants because it does not produce secondary pollution during use. However, the reaction between ozone and organic matter is extremely complicated, and the reaction is affected by water pH, ozone concentration, Factors such as the concentration of organic matter, water body temperature, and reaction time have a great influence, so the research on the reaction mechanism, reaction equation, and reaction products of ozone and organic matter is not yet sufficient. The chemical reaction kinetics is a very important means to master the reaction...
