Environmental assessment of mercury pollution in urban tailings from gold mining
(Elsevier Inc., 2013)
It is well-known that small-scale artisanal mining is a source of mercury emissions into the environment, mainly from the use of rudimentary technologies that use mercury amalgamation in the extraction process. Mines near ...
Isolation and characterization of mercury resistant trichoderma strains from soil with high levels of mercury and its effects on Arabidopsis thaliana mercury uptake
(Scientific Research Publishing Inc, 2019)
Flow-through polarographic cell for flow-injection analysis. Determination of nifedipine in pharmaceutical formulations
(JOHN WILEY & SONS INC, 1997)
A simple design of a polarographic flow-through cell is proposed in which a conventional dropping mercury electrode (DME) is used as working electrode, and a mercury pool and a platinum wire are used as the reference and ...
A thermal analysis study of dithizone and dithizonates of mercury, silver and bismuth
(Editora Unesp, 2000-01-01)
Foram preparados os ditizonatos de Hg (I), Ag (I) e Bi (III). Termogravimetria (TG), termogravimetria derivada (DTG), calorimetria exploratória diferencial (DSC), difratometria de raios X pelo método do pó e análise elementar ...
Comparative Measurements and their Compliance with Standards of Total Mercury Analysis in Soil by Cold Vapour and Thermal Decomposition, Amalgamation and Atomic Absorption Spectrometry
(2013)
Two methods to measure mercury concentration
in soil are compared, and their compliance with
international standards is determined: cold vapour atomic
absorption spectrometry and thermal decomposition,
amalgamation and ...
Preconcentration and determination of mercury(II) at a chemically modified electrode containing 3-(2-thioimidazolyl)propyl silica gel
(2005-11-01)
A mercury-sensitive chemically modified graphite paste electrode was constructed by incorporating modified silica gel into a conventional graphite paste electrode. The functional group attached to the (3-chloropropyl) ...

Synthesis and characterization of a novel fluorescent and colorimetric probe for the detection of mercury (II) even in the presence of relevant biothiols
(Elsevier, 2015)
We present here a novel probe, coumarin 3-azomethine derivative (AGB), which can detect selectively mercuric ions (Hg2+) via a hydrolysis reaction promoted by these ions. Interestingly, the probe can be used to assess the ...
