摘要
为探讨萃取时间和冷却时间对纺织品可萃取重金属检测结果的影响,选择国内相关标准中限量值较大(≤30 mg/kg)的重金属锑作为代表性研究对象.通过对实际测量值接近限量值的稳定样品单因子周期性持续监测分析,确定萃取时间和冷却时间对检测结果的实际影响程度.通过锑相关纺织品的工艺和菲克定律,对监测结果进行详细分析,确认了萃取时间和冷却时间对纺织品可萃取重金属检测结果的正向性影响,为试验室在执行相关检测标准时需要关注和规范的重点提供参考.
Abstract
To confirm the impact of extraction time and cooling time on the detection results of extractable heavy metals in textiles,antimony,a heavy metal with a higher limit value(≤30 mg/kg)in relevant domestic standards,was selected as a representative research object.By continuously monitoring and analyzing stable samples with actual measurement values close to the limit value through single factor periodic monitoring,the actual impact of extraction time and cooling time on the detection results was determined.Through the process of antimony related textiles and Fick's law,a detailed analysis of the monitoring results was conducted,confirming the positive impact of extraction time and cooling time on the detection results of extractable heavy metals in textiles,providing a reference for the key points that laboratories need to pay attention to and regulate when implementing relevant testing standards.
