Embodiment 1

[0107] Embodiment 1, a kind of detection method (that is, the detection method of the migration amount of phosphate plasticizer in textiles in acidic sweat) that is applicable to the migration amount of phosphate plasticizer in textiles, carries out the following steps successively :

[0108] 1) Establishment of migration system

[0109] (A) Take the sample to be tested, cut it into small pieces of about 5mm×5mm, and mix well. Weigh an appropriate amount of 1g of the above-mentioned shredded sample, accurate to 0.01g, place it in a 50mL plastic centrifuge tube with a screw cap (as an extractor), and add 20mL of artificial simulated acidic sweat;

[0110] (B) In order to simulate the friction between the human body and textiles, add an appropriate amount (10 pieces) of small glass beads with a diameter of 0.50 cm into the centrifuge tube, place it in a water bath oscillator with a water temperature of 37 ° C, and oscillate at a speed of 300 rpm for 30 min and 60 min respective...

Embodiment 2

[0131] Embodiment 2, a kind of detection method that is applicable to the migration amount of phosphate ester plasticizer in acidic sweat in textiles, its difference with embodiment 1 is as follows (all the other are equal to embodiment):

[0132] The gradient standard solution is injected into the gas chromatography-mass spectrometer, and the selected ion monitoring (SIM) mode is measured to determine the peak position of each phosphate plasticizer, and the corresponding peak area is recorded. Taking the concentration as the abscissa, the peak area is Ordinate, make the standard curve equation;

[0133] Described gas chromatography-mass spectrometry detection method instrument condition is:

[0134] Chromatographic column: DB-5MS, 30m×0.25mm×0.25μm; chromatographic column heating program: 70°C, keep warm for 0min; increase the temperature at 25°C / min to 280°C, keep warm for 6min;

[0135] Carrier gas flow rate: 1mL / min; inlet temperature: 250°C; ion source is electron bombar...

Abstract

The invention discloses a method for detecting transfer volume of phosphate ester plasticisers in acid sweat in textile. The method comprises the following steps: utilizing a to-be-tested sample to establish a transfer system so as to obtain a transfer liquid; utilizing the transfer liquid to prepare a to-be-tested sample solution so as to obtain a supernatant liquid; preparing the phosphate ester plasticisers into a gradient standard solution; injecting both of the gradient standard solution and the supernatant liquid into a gas chromatograph or a gas chromatograph-mass spectrometer, and performing flame photometry detector testing or selected ion monitoring mode testing so as to obtain the content of the phosphate ester plasticisers in the supernatant liquid; finally obtaining content of the phosphate ester plasticisers in the to-be-tested sample. The phosphate ester plasticisers are triphenyl phosphate, tri-ortho-cresyl phosphate, cresyl phosphate, tri-o-cresyl phosphate, tributyl phosphate, trioctyl phosphate, dpof diphenyl octylphosphate, cresyl diphenyl phosphate isomer CDP I and cresyl diphenyl phosphate isomer CDP II.

Description

technical field [0001] The invention relates to a method for detecting the migration amount of phosphate plasticizers in textiles in acidic sweat. Background technique [0002] At present, the commonly used phosphate plasticizers at home and abroad include tributyl phosphate (TBP), trioctyl phosphate (TOP), triphenyl phosphate (TPP), tricresyl phosphate (TCP), diphenyloctyl phosphate ester (DPOP), cresyl diphenyl phosphate (CDEP) and many other varieties. Among the aromatic phosphates, tricresyl phosphate (TCP) has the largest yield, followed by cresyl diphenyl phosphate (CDEP) and triphenyl phosphate (TPP). It is often used under the requirements of flame retardancy, and the output of trioctyl phosphate (TOP) is also large. It is insoluble in water, easily soluble in mineral oil and gasoline, has flame retardant and anti-mildew effects, and has good low temperature resistance. In a wide temperature range, its flexibility does not change significantly, but its mobility and...
