Heavy Metal Detection in Treated Water Via a Fabric Nanocomposite SensorWe present the conception of an electrochemical sensor for on-site/portable water analysis. This flexible sensor was developed to quantify the amount of heavy metals (in real-time), alleviating the wait time, large sample size...

New mercaptoacetic acid incorporated NU-1000 Metal Organic Frameworks (MOF) is presented. • Fluorescence spectroscopy is used for detection of Hg2+ ions in water. • The new MOF can selectively detect Hg2+ ions in water. Abstract Interest in the design and use of metal-organic frameworks ...
Under the optimal conditions, the calibration curve was linear in the range of 10-800 μg L(-1) for Cu and Ni, 10-500 μg L(-1) for Pb, and 10-1,000 μg L(-1) for Cd, respectively. The limits of detection for the four metal ions were below 0.5 μg L(-1), with the ...
Heavy metal ions are one of the main sources of water pollution. Most heavy metal ions are carcinogens that pose a threat to both ecological balance and human health. With the increasing demand for heavy metal detection, electrochemical detection is favorable due to its high sensitivity and effici...
The objective of this paper is to assess the impact of long-term electroplating industrial activities on heavy metal contamination in agricultural soils an
Here, we explore the adsorption of neutral, monovalent and divalent ions of Cd, Hg and Pb on both graphene quantum dots and infinite graphene, in order to determine their suitability as sensors for heavy metal detection. Results and Discussion The current section is organized as follows. First,...
Water resources in the world have been profoundly influenced over the last years by human activities, whereby the world is currently facing critical water supply and drinking water quality problems. In many parts of the world heavy metal (HM) concentrations in drinking water are higher than some ...
Zhao et al. (2008b,2010) have demonstrated extensively that the dissolved metal front from mines may become unstable when it propagates in the soil/rock. The dissolved heavy metals can be transported in the soil/rock through pore-water advection, convection and solute diffusion/dispersion, and ...
Lake sediments are a sink for heavy metals13,14, and heavy metal concentrations are generally higher in sediment than in water15. Indeed, concentrations of heavy metals in water are sometimes lower than detection limits, meaning that sediment should be analysed to assess levels of contamination by...
