Abstract

Building materials are the main products made of coal gangue and coal fly ash. Most of these products contain various heavy metals such as Pb, Cd, Cr, Hg, which are needed to measure in the purpose of safe using and environment protection. In our work, we established a set of method to pre-treat the products by microwave digestion technique and measure the concentration of heavy metals by atomic absorption spectrophotometer. And we measured three products from Shuozhou City, Shanxi Province and found that the content of one or two kinds of heavy metals are high, which should be paid great attention in its application for their high environmental risks.
