Determination of decabromodiphenyl ether in backcoated textile preparation

Kinetics of the release of antimony trioxide from the backcoated textile preparation

“…The analysis of the unaged textile samples revealed that they contained ~91%wt:wt of the claimed concentration of ATO in Type A (ATO-HBCD) samples compared to ~70 %wt:wt of the theoretical concentration of ATO claimed to exist in type B backcoated samples. Samples of the same textile were then thermally aged or exposed to UV light at 340 nm for different periods of time [1,2]; at the end of the ageing period, samples of both types, A and B, were analysed and their ATO content was determined. Table 1 and 2 show the results of the complete extraction of the thermally and UV aged samples at the end of the ageing period, these results indicate that the total recovery of antimony trioxide concentrations decreased due to ageing conditions (like other brominated FR) [1,2].…”

“…A direct comparison of the weight loss with the blank samples (i.e., samples containing no flame retardant) and the ones containing (FR) revealed that the main source for the weight loss of the thermally or UV aged textile samples can be attributed to the release of FR [1,2], which matched with similar results obtained in literatures [2,25], from the present results and taken into accounts mass balance we can conclude that the total weight loss is attributed to the loss of both halogenated FR and ATO [2,25]. 3 Results are averaged of three repeated samples.…”

“…Detailed extraction and analytical methods were investigated earlier [2,26]. Validation of the analytical and the extraction methods described earlier [1,26]. The method include; study of the repeatability of analytical method and extraction methods, determination of the linear range by dilution of standard solutions, then estimation of the limit of quantification using standards, and finally, spike each matrix that is subject to extraction to determine the recovery of each extraction method, and compare with blanks [1,2], as a result a complete and validated analytical method for both extraction and analytical method was produces with linear calibration curve in range of 5 to 220 ng with detection limit of 5 ng [26].…”

“…Table 3, shows the results of the analysis of ATO extracting solutions from the textile fabric samples previously exposed to UV light (lamp at 340 nm, radiation intensity 1.25 W.m 2 ) for 200 days [1,2], for type A samples; the extracted antimony trioxide was found to be 52.0±2.7% of the theoretical concentration originally present in the unaged samples indicating that 38% had been lost due to UV exposure. For type B (ATO-BDE 209) samples; the extracted antimony trioxide was found to be 54.6±3.3% of the theoretical concentration originally present in the unaged samples indicating that 15.4% had been lost due to UV exposure.…”

“…Flame retardant (FR) materials could be defined as chemicals used to prevent or at least delay the spread of fire through disrupting the combustion step of a fire cycle, this can be done by delaying the time of flashover by slowing down the initial burning rate [1]. FR material used mainly in consumer products (i.e., furniture, textiles, electronics, and insulation, etc.).…”
