Abstract Both acid digestion and high definition X-ray fluorescence spectrometry (HDXRF) methods were used to measure the contents of Cu, Pb, Zn, Ni and Cd for 24fly ash samples. The good correlation(coefficient of determination R²≥0.90) determined by linear regression analysis between the results from these two methods demonstrated that HDXRF was an accurate and rapid technique for the determination of heavy metal content. Then, HDXRF was used to evaluate fly ash samples collected from a typical grate incinerator for six months. The results showed thatthe monthly average contents of heavy metals remained consistent with coefficient of variation (CV) less than 0.14, whiletheir daily average contents fluctuated significantlywithCV over 2.54; changes in contents of Pb, Cu and Zn were positively correlated; andthe metal leaching concentration was significantly affected by the pH of the end point of the leaching solution, Pb and Cd were the elements that exceed the stipulated limit (GB 16889-2008) most, followed by Ni, Cu and Zn.The short-term variations of metal contents and leaching toxicity were affected by many factors, including the conditions of incineration, purification technologies of flue gas, and compositions of wastes, et al. To assess the effectiveness of garbage sorting in reducing heavy metals at source, a rapid detection method (e.g., HDXRF) could be adopted to monitor heavy metal contents of fly ash for a long period.
