摘　　要：通过单因素试验法分别对消解温度、消解时间、硝酸用量和双氧水用量对样品中铅含量的影响进行了研究,以便优化纺织品附件中铅的微波消解方法。结果发现:适用于非金属材质附件微波消解的条件为消解温度180℃、消解时间10 min、硝酸用量4.5 m L、双氧水用量0.6 mL;就大部分纺织品金属材质附件而言,加入3.5~5.5 mL的硝酸便可以取得很好的消解效果。In order to optimize the microwave digestion method of lead in textile accessories, the effects of digestion temperature, digestion time, nitric acid dosage and hydrogen peroxide on the content of lead in textiles were studied by single factor test method. The results showed that the suitable conditions for microwave digestion of non-metallic materials were as follows: digestion temperature180 ℃, digestion time 10 min, consumption of nitric acid 4.5 mL and hydrogen peroxide 0.6 mL, and a good digestion effect could be obtained by adding 3.5 ~ 5.5 mL nitric acid for most textile metal accessories.
