摘要

This research analyzed the distribution of fifteen trace elements from thirty-two fly ash samples collected from four countries. The inductively coupled plasma/ mass spectrometry analyses of acid extracts show that concentrations of heavy metals in fly ashes vary from one country and power plant to another. Coagulants produced from these fly ashes need to be analyzed and tested to prevent levels of heavy metals that are higher than desirable in wastewaters treated with these.
