Label-free fluorescence detection of mercury ions based on the regulation of the Ag autocatalytic reaction

15-Apr-2015 | Haichao Dai; Pengjuan Ni; Yujing Sun; Jingting Hu; Shu Jiang; Yilin Wang; Zhuang Li, Analyst, 2015

In this work, a novel facile nanoparticle autocatalytic sensor based on the inhibition of the Ag autocatalytic reaction for the determination of Hg2+ was developed. o-Phenylenediamine (OPD) tended to be oxidized into 2,3-diaminophenazine (OPDox) by silver ions (Ag+) followed by the formation of ...

Sustainability, Vol. 7, Pages 4049-4062: Mercury in the Urban Topsoil of Athens, Greece

08-Apr-2015 | Kelepertzis, Efstratios ; Argyraki, Ariadne, Sustainability, 2015

The present study documents the Hg content in 45 urban topsoil samples from the highly urbanized city of Athens, Greece. The Hg concentrations were quantified by applying aqua regia digestion on the <100 μm soil fraction followed by inductively coupled plasma-mass spectrometry (ICP-MS) with a ...

Coordination Chemistry of Mercury-Containing Anticrowns. Complexation of Perfluoro-o,o′-biphenylenemercury with o-Xylene and Acetonitrile and the First X-ray Diffraction Evidence for Its Trimeric Structure

07-Apr-2015 | Kirill I. Tugashov; Dmitry A. Gribanyov; Fedor M. Dolgushin; Alexander F. Smol’yakov; Alexander S. Peregudov; Irina ..., Organometallics, 2015

The paper reports the first X-ray diffraction data evidencing the cyclic trimeric structure of the earlier synthesized octafluoro-o,o′-biphenylenemercury (8), being of considerable interest as a potential anticrown. The conclusion on the trimeric (o,o′-C6F4C6F4Hg)3 structure of this mercuracycle ...

Mercury Retention by Fly Ashes from Oxy-fuel Processes

07-Apr-2015 | Nuria Fernández-Miranda; Marta Rumayor; M. Antonia Lopez-Anton; Mercedes Díaz-Somoano; M. Rosa Martínez-Tarazona, Energy & Fuels, 2015

The objective of this study is to determine the mechanism of mercury retention in fly ashes, the main solid waste from coal combustion power plants, and to evaluate the interactions between the type of mercury and fly ashes. The work was based on the results of mercury speciation in the gas and ...
