| 对各种类型的聚氨酯塑胶跑道进行HNO3-HClO4消化体系湿法处理，利用火焰原子吸收分光光度法测定其中重金属的含量。结果表明：塑胶跑道中重金属铅、锌、铬、镉含量很高。方法的加标回收率分别为99.37%、99.52%、92.97％、92.39％。RSD值分别为6.497%、 4.186%、7.910％、12.65％ |

| Different types of polyurethane synthetic rubber sports track materials were digested with HNO3-HClO4. The flame atomic absorption spectrophotometry was used to test the heavy metal contents. The results showed that the content of lead, zinc, chromium and cadmium were very high. The rates of standard recovery of lead, zinc, chromium and cadmium were 99.37%, 99.52%, 92.97%, and 92.39% respectively. RSD values were 6.497%, 4.186%, 7.910％and 12.65％respectively. |
