摘要： Boiler slag derived from coal combustion plants was explored as the experimental material for recycling aluminum and iron for the production of a sulfate-based complex coagulant containing ferric sulfate and aluminum sulfate. The boiler slag sample was determined for more complete characterization by means of scanning electron microscopy (SEM), X-ray fluorescence (XRF) and other techniques. This boiler slag was evaluated to determine the efficiency of converting the iron and aluminum components of the material into a sulfate-based complex coagulant. The maximum concentrations of Fe3+ and Al3+ in the complex coagulant prepared from the boiler slag were obtained at 130 r and after 3 h of reaction time. The corresponding conversion efficiencies of aluminum and iron were 66.2 and 95.0% in the boiler slag, respectively.
