Abstract

Mercury is a toxic heavy metal and is present in air and water both. Its increasing concentration levels are matter of concern. Elemental mercury sorption is very popular Convention sorbents like fly ash and charcoal etc has limited sorption capacity. This work discusses the standard sorbent synthesis rout and effect of surface modification for mercury sorption. It also compares the sorption capacities of various sorbents with and without surface modification and explains the reasons behind increasing sorption capacities with surface modification. This work is very useful for the researchers working in advance sorbent synthesis and air pollution abatement. This also provides and understanding for selecting sorbent for mercury respirator cartridges.
