Thermodynamic and experimental study of the degradation of the red pigment mercury sulfide

06-Jan-2015 | Marie Radepont; Yvan Coquinot; Koen Janssens; Jean-Jacques Ezrati; Wout De Nolf; Marine Cotte, Journal of Analytical Atomic Spectrometry, 2015

The red pigment mercury sulfide, called cinnabar or vermilion, is well known to suffer from an alteration giving rise to a grey, grey-white or black colour at the surface of degraded works of art. This phenomenon can dramatically affect the esthetical value of artworks. This work aims at ...


Determination of methylmercury in marine biota samples with advanced mercury analyzer: Method validation

04-Jan-2015 | Author(s): Sabine Azemard , Emilia Vassileva, Food Chemistry, 2015

Publication date: 1 June 2015 Source:Food Chemistry, Volume 176 Author(s): Sabine Azemard , Emilia Vassileva In this paper, we present a simple, fast and cost-effective method for determination of methyl mercury (MeHg) in marine samples. All important parameters influencing the sample ...


Tracking Overwintering Areas of Fish-Eating Birds to Identify Mercury Exposure

31-Dec-2014 | Raphael A. Lavoie; T. Kurt Kyser; Vicki L. Friesen; Linda M. Campbell, Environmental Science & Technology, 2014

Migration patterns are believed to greatly influence concentrations of contaminants in birds due to accumulation in spatially and temporally distinct ecosystems. Two species of fish-eating birds, the Double-crested Cormorant (Phalacrocorax auritus) and the Caspian Tern (Hydroprogne caspia) ...


A low content Au-based catalyst for hydrochlorination of C2H2 and its industrial scale-up for future PVC processes

31-Dec-2014 | Kai Zhou; Jinchao Jia; Chunhua Li; Hao Xu; Jun Zhou; Guohua Luo; Fei Wei, Green Chemistry, 2014

China has the world's largest polyvinyl chloride (PVC) production capacity, comprising over 20 Mt a−1 and occupying 41% of the world production capacity. However, the production of the PVC monomer, vinyl chloride monomer (VCM), faces unsustainable development due to mercury problems. Over 70% of ...


Online mercury determination by laser-induced breakdown spectroscopy with the assistance of solution cathode glow discharge

30-Dec-2014 | Peichao Zheng; Hongdi Liu; Jinmei Wang; Minjie Shi; Xiaomeng Wang; Bin Zhang; Rui Yang, Journal of Analytical Atomic Spectrometry, 2014

The trace mercury in an aqueous solution was determined by laser-induced breakdown spectroscopy (LIBS) with the assistance of a solution cathode glow discharge (SCGD) system. The aqueous solution was converted to the gas phase using a high voltage DC discharge, and then the generated mercury ...


Structures of NHC Hg(II) and Ag(I) Complexes and Selective Recognition of Nitrate Anion

30-Dec-2014 | qingxiang liu; Zhi-Xiang Zhao; Xiao-Jun Zhao; Qing Wei; Ai-Hui Chen; Hui Long Li; Xiu-Guang Wang, CrystEngComm, 2014

A series of bis-benzimidazolium (or bis-imidazolium) salts, and their eight N-heterocyclic carbene mercury(II) and silver(I) complexes 1-8 have been synthesized and characterized. Complexes 1-4 and 6 contain similar macrometallocycles formed via one bidentate carbene ligand and one metal ion. ...


Determination of Mercury in Iron Supplement Using Slurry Sampling and Cold Vapor Atomic Absorption Spectrometry

30-Dec-2014 | A. Barbosa, Uenderson; O.B. Silva, Laiana; Ferreira dos Santos, Ivanice; L.C. Ferreira, Sergio; M.P. dos Santos, Ana, Current Analytical Chemistry, 2014

Abstract: This paper proposes a method using slurry sampling and cold vapor atomic absorption spectrometry (CV AAS) for the determination of mercury in iron supplement used for the treatment of anemia. The optimization step of the slurry preparation was performed using a two-level full ...


Synthesis of a carbon-dot-based photoluminescent probe for selective and ultrasensitive detection of Hg2+ in water and living cells

30-Dec-2014 | Sasmita Mohapatra; Swagatika Sahu; Niharika Sinha; Sujit K. Bhutia, Analyst, 2014

A nitrogen and sulphur co-doped carbon dot (NSCD) based highly selective photoluminescent probe for mercury detection has been designed. The NSCDs with a PL quantum yield of 69% are easily prepared from a single polymeric molecular precursor. The turn on-off fluorescence change upon mercury ...


Sensors, Vol. 15, Pages 592-610: Simultaneous Automatic Electrochemical Detection of Zinc, Cadmium, Copper and Lead Ions in Environmental Samples Using a Thin-Film Mercury Electrode and an Artificial Neural Network

30-Dec-2014 | Kudr, Jiri ; Nguyen, Hoai Viet; Gumulec, Jaromir ; Nejdl, Lukas ; Blazkova, Iva ; Ruttkay-Nedecky, Branislav ; Hynek ..., Sensors, 2014

In this study a device for automatic electrochemical analysis was designed. A three electrodes detection system was attached to a positioning device, which enabled us to move the electrode system from one well to another of a microtitre plate. Disposable carbon tip electrodes were used for ...


Hydration characteristics of cement for co‐sintered from washed‐fly ash and waste sludge

29-Dec-2014 | Kae‐Long Lin, Kang‐Wei Lo, Je‐Lueng Shie, Bui Le Anh Tuan, Chao‐lung Hwang, Yu‐Min Chang, Environmental Progress, 2014

The purpose of this study is to co‐sinter washed‐fly ash, limestone sludge, stone sludge, and iron‐oxide sludge to fabricate 4 types of eco‐cement clinkers. The compound raw materials were burned for 2 h at 1400°C to form the eco‐cement clinkers, all of which met the toxicity characteristic ...
