Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard is proposed by China Light Industry Federation. This standard is under the jurisdiction of the National Standardization Technical Committee on Surfactants and Detergents (SAC/TC272). This standard was drafted by. China Daily Chemical Industry Research Institute [National Detergent Quality Supervision and Inspection Center (Taiyuan)], Shenzhen Barger US Biotechnology Co., Ltd., Fuling Entry-Exit Inspection and Quarantine Bureau, Xi'an Kaimi Co., Ltd., Shanxi Energy Product Quality Supervision and Inspection Research Institute. The main drafters of this standard. Wu Jie, Li Hongyu, Li Qing, Yu Wen, Yao Chenzhi. Determination of triclosan content in detergents

1 Scope

This standard specifies the HPLC method for the determination of triclosan in detergents. This standard applies to the determination of triclosan in detergents.

2 Normative references

The following documents are indispensable for the application of this document. For dated references, only dated versions apply to this article Pieces. For undated references, the latest version (including all amendments) applies to this document. GB/T 6682 Analysis Laboratory Water Specifications and Test Methods

3 Principle

The sample is dissolved in the mobile phase, ultrasonically extracted, and the extract is filtered to configure the UV detector or diode array detector for high efficiency Determination of liquid chromatography. According to the determination of the retention time of the measured components, quantification by external standard method.

4 Reagents and materials

Unless otherwise indicated, only analytically pure reagents and secondary water according to GB/T 6682 were used in the analysis. 4.1 Methanol. Chromatographically pure. 4.2 Triclosan (Triclosan, CAS. 3380-34-5, molecular formula. C12H7Cl3O2). Purity greater than or equal to 99%. 4.3 Triclosan stock solution. Precisely and accurately weigh 100mg triclosan (4.2), dissolve in methanol and make up to 100mL, formulated into a concentration A stock solution of 1000 mg/L was stored in a refrigerator at 4°C, and a standard solution was prepared according to the need to prepare a standard solution with appropriate concentration. 4.4 Filter. Organic, 0.45 μm.

5 Instruments and Equipment

5.1 HPLC. Equipped with a diode array or UV detector. 5.2 Analytical balance. The amount of sense is 0.1mg. 5.3 Ultrasonic cleaners. 5.4 Centrifuge. The speed is not less than 4000r/min.

6 Determination

6.1 Sample preparation Weigh 0.5g of liquid or cream sample (solid sample 0.2g) (accurate to 1mg), place in a 25mL volumetric flask, add 15mL The mobile phase was extracted with ultrasound for 20 min, diluted with mobile phase to the mark and mixed. If the solution is cloudy, transfer the volume of the extracted solution to The tube was centrifuged at 4000r/min for 10 min. After centrifugation, the supernatant was filtered through a filter (4.4). The resulting filtrate was determined by high performance liquid chromatography. ......
