Concerns on liquid mercury and mercury-containing wastes: A review of the treatment technologies for the safe storage

摘要

Due to the adverse effects of mercury on human health and the environment, restrictive legislations and\udworld-wide common efforts are now under way to reduce both the supply and demand of mercury. As\uda result, all excess Hg must be stored in safe conditions in secure places. This paper is an attempt to\udreview the various treatment technologies types of liquid mercury (Hg0) and mercury-containing wastes,\udwhich can be used to store these residues in a safe way. The different treatments were classified as\uda function of the waste treated. The main treatments described are amalgamation, formation of sulfides,\udthermal treatments, vitrification, soil washing, sulfur polymer stabilization solidification, chemically\udbonded phosphate ceramics and other encapsulation processes, being highlighted the stabilization/\udsolidification processes that are the treatments that provide better results, according to the consulted\udbibliography
