Title: Analysis of the test methods of heavy metal in eco-cement
Abstract: Heavy metals in eco-cement restrict the application and development of cement kiln to treat hazardous wastes.Three analysis methods to detect heavy metals in cement including total amount and leaching characteristic were studied.Results show that:(1)X-ray fluorescence spectrometer is the best method to detect total concentration of heavy metals in eco-cement.(2)Solid waste-extraction procedure for toxicity of solid waste is not suitable for cement system.(3)Long-term leaching test can be used to predict the long term leaching characteristic under certain situation.All the results can be used to constitute standards and criterion for co-firing technology using cement kiln.
