Abstract

The toxic nature and other adverse of the heavy metals lead to pollution and make it one of the most serious problems that affect certain sides of the environment. There are many heavy metal ions like the mercuric ions detected in industrial wastewaters originating from several factors such as from metal plating, mining activities, paint manufacture, etc. The above-mentioned ions isn't biodegradable and tends to be accumulated in living organisms, causing various diseases and disorders. Therefore, it must be removed from aqueous solution before discharge. In this paper, an experimental work it has been done regarding the optimal conditions of removing Hg (II) ions from water using chelating ion exchange resin namely XAD- & Pendant Multidentate Ligand Resin. The adsorption behaviour of mercury ions on XAD-& Pendant Multidentate Ligand Resin was studied as a function of the following variables: contact time, pH solutions, initial concentration of metal ions and resin dosage the adsorbent's maximum total adsorption capacity of for mercuric ions was: 0.82 mmol/g dry resin. The resin low affinity towards alkali and alkaline earth metals shows its use for samples that related to environment. The concluded results state that, XAD- & Pendant Multidentate Ligand Resin holds great potential for the purpose of removing mercuric ions from polluted wastewater.
