Inertisation of heavy metals in municipal solid waste incineration fly ash by means of colloidal silica – a synchrotron X-ray diffraction and absorption study

Rudolf Paul Wilhelm Jozef Struis

Many efforts have been undertaken in past decades to minimize pollution from municipal solid waste incineration fly ash (MSWI FA). This residue is toxic, because of its high concentration of heavy metals, mainly Pb and Zn. A new method for heavy metals ent ...
