Embodiment 1

[0044] Embodiment 1, the steps are as follows:

[0045] (1). Utilize the ozone generator to generate ozone, the ozone flow rate is 100ml / min, and the concentration is 2mg / l, which is sent into the ozone chamber 9 of the TOC reaction chamber, and enters the water sample reaction chamber 3 through the filter isolator 7;

[0046] (2). The water sample to be tested is heated up to 40°C through the filtering and heating device, and is input into the water sample reaction chamber 3 of the TOC reaction chamber by the flow pump;

[0047] (3). The ozone and the water sample are mixed and reacted in the water sample reaction chamber 3, so that the ozone and the water sample can be fully mixed to generate an optical signal;

[0048] (4). Use the photomultiplier tube 1 in the TOC reaction chamber to collect and amplify the optical signal emitted by the reaction, and convert it into an electrical signal and send it to the microcomputer data processing system. After the processed signal is ...

Abstract

This invention relates to one method to test water total organic carbon, which comprises the following steps: a, sending ozone into TOC reacting room and then into water sample reaction room after filtering and isolator; b, the sample going through heating device and flowing into sample reaction room of TOC reactor through flow pump; c, the ozone and sample reacting in the room to generating optical signals; d, collecting and amplifying the signals sent by the electron-multiplier phototube in the TOC reactor and converting into electrical signals into micro computer process system and after signal processing and comparing data with standard relative curve for displaying and printing and outputting test data.

Description

technical field [0001] The invention belongs to the technical field of environmental chemical monitoring, in particular to a method for measuring water body total organic carbon (TOC) by utilizing the principle of chemiluminescence in an ozone oxidation process. Background technique [0002] Total organic carbon, the English name is Total Organic Carbon, abbreviated as TOC. At present, domestic methods for measuring total organic carbon (TOC) are generally based on laboratory platforms, and the principles adopted mainly include the following: (1). High-temperature catalytic combustion-non-dispersive infrared detection (NDIR), that is, high-temperature oxidation method; (2). Oxidation with oxidants such as persulfate - non-dispersive infrared detection (NDIR), that is, wet oxidation; (3). Ultraviolet (UV) - persulfate oxidation - non-dispersive infrared detection (NDIR), that is, ultraviolet humidification Analytical methods such as oxidation. [0003] (1). The principle of...
