“…The LOD was much lower than the Hg 2+ detection limit set by WHO (30 nM) and the U.S. environmental protection agency (10 nM). 3,4 In addition, the obtained LOD is about ∼42 times higher than the Au nanoparticles prepared with GS of a larger alkyl chain length. 22 The limit of detection reported in this work for Au nanoparticles synthesized with (14-2-14) is 1.8 nM higher than the 107, 76, and 176 nM for (16-2-16), (18-2-18), and (20-2-20) GS, respectively.…”

We report an excellent anisotropic Au nanoparticle-based colorimetric probe for the detection of Hg 2+ ions with higher detection ability and selectivity. The manifestation of different morphologies of Au nanoparticles including round, triangular, rectangular, pentagonal, and hexagonal has been realized by the dimethylenebis-(tetra-decyldimethylammonium bromide) (14-2-14 Gemini surfactant) assisted one-step thermal reduction method where the average size of Au nanoparticles was 54.65 ± 44.3 nm. The growth and frequency of Au nanoparticles were enhanced as a function of Gemini surfactant’s concentration. The detection limit as low as 1.8 nM was efficaciously achieved and was considerably lower than the required world standards defined the maximum allowable level of Hg 2+ ions for health hazards. Notably, the Au nanoparticles showed visible detection for 100 μM Hg 2+ ion by means of the change in the solution color from red to tarnish blue within 180 s followed by saturation in the absorption ratio ( A LSPR / A TSPR ). These results provide novel insight into the detection of the heavy metal ion using Gemini surfactant-assisted grown anisotropic metal nanoparticles. On the basis of obtained results, it is concluded that the size of metal nanoparticles is no longer critical for preparation of efficient selective chemoprobe; rather, growth of more number of edges provides a large number of sights for incoming moieties and plays an important role in improving the detection capability of the anisotropic metal nanoparticle irrespective of their large sizes. We believe that this work provides valuable insight into researchers working in the area of chemosensor applications.

“…Hg emissions are a concern due to their detrimental health impacts and persistence and bioaccumulation in the environment . Coal‐fired power plants are a significant source of anthropogenic Hg emissions, and in the United States (US), they account for over 50% of anthropogenic emissions of Hg to the air .…”

“…To comply with these Hg emissions regulations, research and pilot efforts are being made to reduce Hg emissions. Some methods by which Hg emissions can be reduced include: selective mining of low Hg coals, removal of Hg from the coal supply, optimizing the coal combustion environment for Hg removal, oxidation of Hg in the flue gas to make it more readily captured by existing pollution control equipment, and sorbent injection into the flue gas for Hg capture with subsequent capture of the sorbent material .…”

Pyrolysis of deinked paper sludge to synthesize adsorbents for elemental Hg vapors

Deinked paper sludge (DPS) was pyrolyzed at 600°C, 750°C, and 900°C in dry nitrogen to synthesize adsorbents. The performance of the pyrolyzed DPS for the gas‐phase adsorption of elemental mercury (Hg0) was investigated, and the performance was compared with that of BPL activated carbon as received (Calgon Carbon Corporation). In addition, the adsorption capacities of pyrolyzed DPS for Hg0 were compared with those published for other activated carbon adsorbents. The physical and chemical properties of pyrolyzed DPS and BPL were characterized to assess their differences, and those differences were used to hypothesize reasons for differences in their adsorption performance for Hg0. Characterization of the adsorbents was conducted using BET surface area, X‐ray diffraction, thermal gravimetric analyses, scanning electron microscopy, electron dispersion spectroscopy, and Fourier transform spectroscopy. Pyrolyzed DPS performed better than BPL for Hg0 adsorption, despite the significant difference in surface area (pyrolyzed DPS ∼50 m2/g; BPL 1100 m2/g). Reasons for differences in adsorption performance are likely due to the pore size distribution, presence of and access to surface active sites, and morphology of the pyrolyzed deinked paper sludge compared with BPL. © 2012 American Institute of Chemical Engineers Environ Prog, 32: 524–534, 2013
