Decontamination of mercury from aqueous media remains a serious task for health and ecosystem protection. Removal of Hg(II) from the aqueous solution by ZnO:S has been investigated and elucidated. The effect of various parameters such as solution pH, adsorbent dose, contact time, initial adsorbate concentration has been studied and optimized. The optimized parameters for metal ion are pH value of 2.4, the equilibrium time was attained after 30 min, and the maximum removal percentage was achieved at an adsorbent loading weight of 0.08 g. It was found that the adsorption capacity of ZnO:S increased with increase in the initial mercury concentration. The equilibrium and kinetic data were found to be in good agreement with Freundlich isotherm model. * Corresponding AuthorsFax: +20 2 26822991 E-Mail: saadsmhassan@yahoo.com (S.S.M. Hassan) [a]

“…Among various technologies developed over the years for mercury removal, adsorption holds great promise due to the simplicity and relatively low-cost of adsorption technology as well as the effectiveness of adsorption method to purify water 6 . A variety of adsorbents have been developed and tested for removing Hg(II) from contaminated waters.…”

Mercury nano-trap for effective and efficient removal of mercury(II) from aqueous solution

et al. 2014

Highly effective and highly efficient decontamination of mercury from aqueous media remains a serious task for public health and ecosystem protection. Here we report that this task can be addressed by creating a mercury 'nano-trap' as illustrated by functionalizing a high surface area and robust porous organic polymer with a high density of strong mercury chelating groups. The resultant porous organic polymer-based mercury 'nano-trap' exhibits a recordhigh saturation mercury uptake capacity of over 1,000 mg g À 1 , and can effectively reduce the mercury(II) concentration from 10 p.p.m. to the extremely low level of smaller than 0.4 p.p.b. well below the acceptable limits in drinking water standards (2 p.p.b.), and can also efficiently remove 499.9% mercury(II) within a few minutes. Our work therefore presents a new benchmark for mercury adsorbent materials and provides a new perspective for removing mercury(II) and also other heavy metal ions from contaminated water for environmental remediation.

“…Unfortunately, if the precipitates were not removed from the water, the mercury can leach out again within hours. Furthermore, SDTC can decompose into byproducts such as tetramethylthiuram and thiram which are toxic to fish [11]. Furthermore, trimercaptotriazine (H 3 TMT) and its trisodium salt (TMT-55) are another type of heavy metal chelating agents that are widely used for chemically precipitating univalent and divalent heavy metals from wastewater and contaminated natural water [12][13][14][15][16].…”
