Fluorescence labeling tracer and preparation method thereof

Abstract

The invention relates to a fluorescence labeling tracer and a preparation method thereof. The fluorescence labeling tracer is a product which is obtained by reacting a polymer of acrylic acid-hydroxy-propyl acrylate copolymer or acrylic acid-acrylamide copolymer and an organic fluorescence derivating agent of L-tryptophan, tyrosine, sulfanilic acid or sodium sulfanilate. The fluorescence labeling tracer is high in sensitivity and selectivity. When used for detecting the concentration of a water treatment agent in an industrial water system, the fluorescence labeling tracer is quick and convenient, and high in repeatability, samples can be taken easily, the required amount of samples is small, and the fluorescence labeling tracer can be used for directly and continuously detecting the running condition of a circulating water system.

Description

technical field [0001] The invention relates to a tracer, in particular to a fluorescent label tracer and a preparation method thereof. Background technique [0002] When the circulating cooling water system is in operation, various substances will be deposited on the surface of the heat exchange tubes, and these substances are collectively referred to as deposits. When anti-corrosion measures are not taken properly, rust tumors often adhere to the surface of the heat exchange tube of the heat exchanger. The deposits formed by these rust-like corrosion products, in addition to affecting heat transfer, will more seriously promote the reproduction of certain bacteria, and eventually lead to corrosion and perforation of the pipe wall and leakage. [0003] In order to solve these problems, a series of water treatment chemicals are usually added to eliminate or slow down the harm caused by corrosion, scaling, sludge and microorganisms, etc., so as to ensure the stable and reliab...

AI Technical Summary

Problems solved by technology

When the concentration ratio of the system is increased or the load is reduced and the dosing amount needs to be reduced, it cannot be automatically reduced, resulting in excessive dosing and waste of medicine

Conversely, when the concentration ratio decreases or the load increases, the discharge increases, and the dose needs to be increased. However, when the amount of the dose should be increased, artificial or conventional mechanical dosing remains unchanged, which often makes the system insufficient. causing system corrosion or fouling

Secondly, even if the metering pump is used to adjust the dosing amount and dosing continuously, due to the hysteresis of the adjustment after detection, when there is a sudden change in the system, such as the increase in the sewage discharge due to the leakage of the system process medium or the addition of water Reduction, the chemical concentration in the system will decrease or increase correspondingly, which will inevitably lead to an increase in scaling or corrosion or a waste of chemical agents

And because the components and inspection methods of various corrosion and scale inhibitors in different circulating cooling water systems are different, more complicated and expensive instruments are required, plus the degradation or decomposition of chemicals, changes in water volume, and interference and error

It makes it difficult to implement the online monitoring of the effective concentration of the medicament, the automatic replenishment of the dosing is useless, and the level of process operation management is difficult to improve. The dosing of most domestic factories is basically in an impact type, which seriously affects the effect of water treatment. Difficult to greatly improve
