An analysis method was established to determine 14 organophosphorus ester (OPE) flame retardants in fall protection equipment by combining accelerated solvent extraction (ASE) and solid-phase extraction (SPE) with high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). The ASE parameters were optimized as follows: static extraction with acetonitrile at 80°C for 5 min for two cycles. The combined extract was purified with the ENVI-18 cartridge before further analysis. A HILIC column was used to separate the OPEs using an acetonitrile/water mixture as the mobile phase with the detection by the electrospray ionization mass spectrometry, which was operated under the positive mode. Under optimized conditions, the limit of detection for the target OPEs ranged in 0.015–1.33 ng/g, with a spike recovery of 71.6%–114% and a relative standard deviation of 0.8%–11.2%. The developed method was used to analyze OPEs in fall protection equipment (safety helmets and ropes), where OPEs were all detectable. Safety ropes displayed a higher concentration of OPEs than ones in safety helmets, with the pollutants being mainly triphenyl phosphate, 2-ethylhexyl diphenyl phosphate (EHDPP), tri(2-ethylhexyl) phosphate, and tri-n-butyl phosphate in the range of 11.07 ng/g‒815.53 ng/g. The EHDPP was the dominant compound in safety helmets with the concentration from 26.84 to 95.29 ng/g, while the other OPEs in safety helmets were lower than 5.136 ng/g. The potential health and environmental risks of these fall protection equipment during their use and disposal call for further attention.

加速溶剂萃取和固相萃取结合LC-MS / MS检测测定防坠落设备中的有机磷酯

建立了一种分析方法,通过结合加速溶剂萃取(ASE)和固相萃取(SPE)与高效液相色谱-串联质谱(HPLC-MS / MS)来确定防坠落设备中的14种有机磷酸酯(OPE)阻燃剂多发性硬化症)。ASE参数的优化如下:用乙腈在80°C静态萃取5分钟,进行两个循环。合并的萃取物用ENVI-18柱纯化,然后进行进一步分析。使用HILIC色谱柱以乙腈/水混合物作为流动相分离OPE,并通过电喷雾电离质谱法进行检测,该方法在正离子模式下运行。在最佳条件下,目标OPE的检出限为0.015-1.33 ng / g,加标回收率为71。6%–114%,相对标准偏差为0.8%–11.2%。所开发的方法用于分析坠落防护设备(安全帽和绳索)中的OPE,在这些设备中都可以检测到OPE。安全绳的OPE浓度比安全头盔中的OPE高,污染物主要为磷酸三苯酯,2-乙基己基二苯基磷酸酯(EHDPP),磷酸三(2-乙基己基)酯和磷酸三正丁酯。 11.07 ng / g‒815.53 ng / g。EHDPP是安全帽中的主要化合物,其浓度在26.84至95.29 ng / g之间,而其他安全帽中的OPE均低于5.136 ng / g。这些跌落防护设备在使用和处置过程中潜在的健康和环境风险值得进一步关注。所开发的方法用于分析坠落防护设备(安全帽和绳索)中的OPE,在这些设备中都可以检测到OPE。安全绳的OPE浓度比安全头盔中的OPE高,污染物主要为磷酸三苯酯,2-乙基己基二苯基磷酸酯(EHDPP),磷酸三(2-乙基己基)酯和磷酸三正丁酯。 11.07 ng / g‒815.53 ng / g。EHDPP是安全帽中的主要化合物,其浓度为26.84至95.29 ng / g,而其他安全帽中的OPE均低于5.136 ng / g。这些跌落防护设备在使用和处置过程中潜在的健康和环境风险值得进一步关注。所开发的方法用于分析坠落防护设备(安全帽和绳索)中的OPE,在这些设备中都可以检测到OPE。安全绳的OPE浓度比安全头盔中的OPE高,污染物主要为磷酸三苯酯,2-乙基己基二苯基磷酸酯(EHDPP),磷酸三(2-乙基己基)酯和磷酸三正丁酯。 11.07 ng / g‒815.53 ng / g。EHDPP是安全帽中的主要化合物,其浓度为26.84至95.29 ng / g,而其他安全帽中的OPE均低于5.136 ng / g。这些跌落防护设备在使用和处置过程中潜在的健康和环境风险值得进一步关注。安全绳的OPE浓度比安全头盔中的OPE高,污染物主要为磷酸三苯酯,2-乙基己基二苯基磷酸酯(EHDPP),磷酸三(2-乙基己基)酯和磷酸三正丁酯。 11.07 ng / g‒815.53 ng / g。EHDPP是安全帽中的主要化合物,其浓度为26.84至95.29 ng / g,而其他安全帽中的OPE均低于5.136 ng / g。这些跌落防护设备在使用和处置过程中潜在的健康和环境风险值得进一步关注。安全绳的OPE浓度比安全头盔中的OPE高,污染物主要为磷酸三苯酯,2-乙基己基二苯基磷酸酯(EHDPP),磷酸三(2-乙基己基)酯和磷酸三正丁酯。 11.07 ng / g‒815.53 ng / g。EHDPP是安全帽中的主要化合物,其浓度为26.84至95.29 ng / g,而其他安全帽中的OPE均低于5.136 ng / g。这些跌落防护设备在使用和处置过程中潜在的健康和环境风险值得进一步关注。EHDPP是安全帽中的主要化合物,其浓度为26.84至95.29 ng / g,而其他安全帽中的OPE均低于5.136 ng / g。这些跌落防护设备在使用和处置过程中潜在的健康和环境风险值得进一步关注。EHDPP是安全帽中的主要化合物,其浓度为26.84至95.29 ng / g,而其他安全帽中的OPE均低于5.136 ng / g。这些跌落防护设备在使用和处置过程中潜在的健康和环境风险值得进一步关注。
