游离碳是环境空气颗粒物中可见的有害成分，也可以作为气溶胶反应的催化剂。本文介绍了一种测定玻璃纤维过滤器上收集的游离碳和总碳的方法。通过燃烧经硝酸处理的暴露过滤器的等分试样来测定游离碳;通过燃烧未经任何预处理的过滤器等分试样来测定总碳。游离碳和总碳的精密度分别为10.6%和1.9%。
Free carbon is a visible, nuisance component of ambient air particulate matter and may also act as a catalyst in aerosol reactions. A method of determining both free and total carbon collected on glass fiber filters is described. Free carbon is determined by combustion of an aliquot of the exposed filter treated with nitric acid; total carbon is determined by combustion of a filter aliquot without any pretreatment. The precision of the method is 10.6% for free carbon and 1.9% for total carbon.
