Problems solved by technology

[0003] The titration of anionic active substances in the national standard adopts the direct two-phase titration method, but this method is only suitable for anionic active substances with a carbon chain length of C8 or more, and allyl sodium sulfonate cannot react with the chromogenic agent
The potentiometric titration method uses the surfactant ion-selective electrode to detect the sudden change potential when the surfactant concentration is below the critical micelle concentration, thereby realizing the detection of the anionic surfactant concentration in the sample, but due to the possible addition of A variety of anionic surfactants will greatly interfere with the quantitative detection of sodium allyl sulfonate

Embodiment 1

[0030] (1) Dilute the water sample containing allyl sodium sulfonate to volume with deionized water, and then perform high-performance liquid chromatography detection to obtain the chromatographic peak area of ​​allyl sodium sulfonate; the chromatographic conditions are as follows:

[0031] Chromatographic column: C18 (4.6mm×300mm, 5μm); column temperature: 25°C; injection volume: 20μL; flow rate: 1.0mL / min; mobile phase: A is methanol, B is 0.02mol / L ammonium acetate solution, A :B=2:98; evaporative photodetector drift tube 95°C, carrier gas flow rate 3.5L / min.

[0032] (2) According to the standard curve of allyl sodium sulfonate y=2.1394x-3.8556 (x is the mass concentration of allyl sodium sulfonate, y is the chromatographic peak area of ​​allyl sodium sulfonate), combined with allyl The chromatographic peak area of ​​sodium sulfonate obtains the content of allyl sodium sulfonate, and the allyl sodium sulfonate content is 58.50mg / L in this sample.

Embodiment 2

[0034] Except that the water sample to be tested containing allyl sodium sulfonate is different, all the other steps are the same as in Example 1, and the content of allyl sodium sulfonate in the sample obtained by HPLC analysis is 72.63mg / L.

Embodiment 3

[0036] Except that the water sample to be tested containing allyl sodium sulfonate is different, all the other steps are the same as in Example 1, and the content of allyl sodium sulfonate in the sample obtained by HPLC analysis is 32.60 mg / L.

Abstract

The invention provides a high performance liquid chromatography detection method of sodium allysulfonate. The method is characterized in that a sample containing sodium allysulfonate is subjected to high performance liquid chromatography detection to obtain the chromatographic peak area of sodium allysulfonate, the chromatographic conditions are that the used chromatographic column is a C18 chromatographic column, a mobile phase A is methanol, a mobile phase B is an ammonium acetate solution, the temperature of a drift tube of an evaporative light detector is 75-100 DEG C, the flow velocity of carrier gas is 3.0-3.5 L / min, the column temperature is 20-40 DEG C, the flow velocity is 0.5 to 1.5 mL / min, and the sample volume is 5-20 [mu]L, and the content of the sodium allysulfonate is obtained according to the standard curve of the sodium allysulfonate in combination with the chromatographic peak area of the sodium allysulfonate. The detection method of the sodium allysulfonate is simple and easy to implement, can rapidly determine the content of the sodium allysulfonate, and is high in accuracy, stability and separation degree.

Description

technical field [0001] The invention relates to a high-performance liquid chromatography detection method for sodium allyl sulfonate, belonging to the technical field of analytical chemistry. Background technique [0002] Sodium allyl sulfonate is produced by the reaction of 3-chloropropene and sodium sulfite. It is a nickel plating brightener that can improve metal distribution and ductility; it is also the third monomer of acrylic fiber, which can improve the dyeing performance of the fiber. , so that the coloring is firm; in addition, sodium allyl sulfonate is also used as an anionic surfactant, water quality treatment agent, oil drilling mud additive, and cement water reducer for construction. When it is used as a brightener for electroplating nickel, it is often compounded with other brighteners to form a composite brightener and added to the electrolyte. The content of sodium allyl sulfonate in the composite brightener is an indicator that technicians in the field of ...
