摘要
塑胶跑道主要有EPDM、复合型、混合型、全塑型、预制型等类型,在生产及铺装过程中,可能会引入重金属元素,如铅、铬、镉、汞等,被人体吸入后,将危及健康,准确测定这些重金属元素的含量,是保证产品质量的关键一环.目前国内塑胶跑道面层中重金属含量检测的方法,包括原子吸收光谱法、电感耦合等离子体发射光谱法、X射线荧光光谱法、电感耦合等离子体发射质谱法、原子荧光光谱法、极谱法等,本文对上述各方法的检测原理、特点和应用进行综述.
Abstract
Plastic runways mainly include EPDM,composite,hybrid,fully plastic,prefabricated and other types.In the production and paving process,heavy metal elements such as lead,chromium,cadmium,mercury,etc.may be introduced.After being inhaled by the human body,it will endanger health.Accurately measuring the content of these heavy metal elements is a key factor in ensuring product quality.At present,there are various methods for detecting heavy metal content in plastic runway surface in China,including atomic absorption spectroscopy,inductively coupled plasma emission spectroscopy,X-ray fluorescence spectroscopy,inductively coupled plasma emission mass spectrometry,atomic fluorescence spectroscopy,polarography,etc.This article reviews the detection principles,characteristics,and applications of these methods.
