摘要：

European Directive 2013/39/EU records mercury as a priority hazardous substance. Regulation no 2008/1102/EC banned the exportation of mercury and required the safe storage of any remaining mercury compounds. The present work describes the encapsulation of three wastes containing combinations of HgS, HgSe, HgCl2, HgO2, Hg3Se2Cl2, HgO and Hg-0, according to patent of Spanish National Research Council WO2011/029970A2. The materials obtained were subjected to leaching tests according to standards UNE-EN-12457 and CEN/TS 14405:2004. The results are compared with the criteria established in the Council Decision 2003/33/EC for the acceptance of waste at landfills. The Hg concentrations of all leachates were <0.01 mg Hg/kg for a liquid/solid ratio of 10 l/kg. All three encapsulated materials therefore meet the requirements for storage in inert waste landfills.
