1 Scope

This standard specifies the principle of using infrared spectroscopy to quickly detect phthalate plasticizers in PVC products, reagents and materials, Equipment, qualitative screening, quantitative analysis and calculation of results This standard applies to the total content of phthalates not less than 1% of the qualitative and quantitative detection of PVC materials.

2 Normative references

The following documents for the application of this document is essential. For dated references, only the dated version applies to this article Pieces. For undated references, the latest edition (including all amendments) applies to this document. GB/T 6040-2002 General rules of infrared spectrometry

3 principle

Preparing a series of standard samples containing phthalate plasticizers, using infrared spectrometer to collect the infrared spectrum data of the standard, according to the standard red Partial Least Squares (PLS) stoichiometry model was established for the characteristic peaks of external spectra, and then the infrared spectra of unknown samples were scanned. 1580cm-1 and 1600cm-1 ring skeleton characteristic absorption peak qualitative analysis, and then using the stoichiometric model of unknown samples of o-benzene two Formate plasticizer total content.

4 Reagents and materials

4.1 Phthalate standards Purity ≥98%, see Appendix A. 4.2 Non-phthalate plasticizers Dioctyl terephthalate (DOTP) and trioctyl trimellitate (TOTM), purity ≥97%. 4.3 standard sample with polyvinyl chloride (PVC) resin. 4.4 Tetrahydrofuran (THF). Spectral purity.

5 equipment

5.1 Fourier transform infrared spectrometer in line with the provisions of GB/T 6040-2002 4.2.1. 5.2 Attenuated Total Reflection (ATR) Accessories. The test crystal is germanium (Ge) crystal. 5.3 Analytical balance. Accuracy of 0.01mg. 5.4 Drying oven temperature fluctuations ± 2 ℃.

6 qualitative screening

6.1 sample preparation Take a flat surface of the test sample, so that it can be close to the ATR attachment crystal surface. ......
