Landfill is becoming a common method to dispose of unwanted or used clothes. The dyes and finishes present on these garments can be a new source of pollution that can potentially leach into soil. A set of knitted cotton fabrics dyed with four common reactive dyes used in the textile industry, C.I. Reactive Orange 35 (RO35), C.I. Reactive Blue 49 (RB49), C.I. Reactive Black 5 (RBlk 5), and C.I. Reactive Blue 19 (RB19), were studied by the ASTM D5988-03 method to determine potential degradation products in landfills. A modified QuEChERS method was used to extract all reactive dyes and derivatives from soil samples in which knitted dyed cotton fabrics were degraded. All extracts were characterized by high-resolution mass spectrometry (HRMS) by using a Quadrupole Time-Of-Flight (Q-TOF) mass spectrometer, where native dyes and their hydrolysis products were identified in soil samples from 45 and 90 day degradation experiments. Four potential degradation derivatives were found and molecular formulas were proposed based on exact mass measurements. These results suggested that traces of reactive dyes and their derivatives from degraded knitted cotton fabrics can be extracted and detected by using a modified QuEChERS method and HRMS.

通过QuEChERS萃取和质谱法检测土壤降解后染色织物中的活性染料

垃圾填埋场正成为处理不需要或用过的衣服的常用方法。这些服装上存在的染料和涂饰剂可能是一种新的污染源，有可能渗入土壤。一组针织棉织物，用纺织工业中使用的四种常见活性染料染色：CI活性橙35（RO35），CI活性蓝49（RB49），CI活性黑5（RBlk 5）和CI活性蓝19（RB19）），通过ASTM D5988-03方法进行了研究，以确定垃圾填埋场中潜在的降解产物。改良的QuEChERS方法用于从降解针织棉织物的土壤样品中提取所有活性染料和衍生物。所有提取物均采用四极杆飞行时间（Q-TOF）质谱仪进行了高分辨率质谱（HRMS）表征，在45天和90天的降解实验中，从土壤样品中鉴定出了天然染料及其水解产物。发现了四个潜在的降解衍生物，并基于精确的质量测量结果提出了分子式。这些结果表明，使用改良的QuEChERS方法和HRMS可以提取和检测降解针织棉织物中的活性染料及其衍生物的痕迹。
