Abstract

The invention relates to the fields of industrial cooling water treating agent and water circular treatment, which provides a polymer containing a double-tracing group and a method for preparing the same. In the polymer, mixed water solution of an unsaturated fluorescence monomer containing trisulfonic acid, maleic anhydride, acrylic acid or itaconic acid, acrylamide or substituted acrylamide, anunsaturated monomer containing sulfonic acid and a non-ion monomer is subjected to copolymerization at a temperature of between 70 and 90 DEG C for 5 to 7 hours so as to obtain a single tracing copolymer with the side chain containing a trisulfonic acid tracing group; and the single tracing copolymer is added with 9-hydroxyxanthene and stirred under the conditions of avoiding light and room temperature for 40 and 60 hours, and is added with methanol for deposition, filtering and refinement, and the polymer containing the double-tracing group is obtained. Because the polymer contains two different structures of fluorescence groups, if the fluorescent background interference exists in the system, the concentration of the polymer can also be detected by another fluorescence group, and the concentration of the polymer in water can be quickly and accurately measured by the fluorescence or spectrophotometry, thereby improving the application range of the polymer.

Description

technical field [0001] The invention relates to the field of industrial cooling water treatment agent or water vapor cycle treatment. Specifically, it relates to a polymer with a novel structure containing double tracer groups and a preparation method thereof. Background technique [0002] The traditional analysis method of water treatment chemicals in industrial circulating cooling water is to analyze the chemicals directly, which is generally cumbersome, and there is no accurate measurement method for the contained polymers. In recent years, the combination of industrial water treatment chemicals and tracers can quickly measure and analyze water treatment agents in industrial circulating water. Compared with other measurement techniques, fluorescent tracer technology has the following advantages: high sensitivity, low detection limit, good selectivity, many spectral parameters, and good controllability. Most of the existing patents adopt the method of mixing fluorescent ...
