For over 40 years, Bernd Kraft® GmbH has produced ready-to-use laboratory chemicals that are supplied in containers from 1 ml to 1,000 l. Our portfolio of more than 10,000 products ranges from standards for chemical analytics, standard solutions, buffer solutions, reagents for analytical more
Mercury has been used and released by humans by multiple processes such as gold and silver mining and emissions of mercury to the atmosphere by coal burning, to name the most important ones. These processes have caused strong enrichment of mercury in the environment especially in aquatic systems. Ho more
Mercury, when dumped in lakes and rivers, accumulates in fish, and often ends up on our plates. A Swiss-American team of researchers led by Francesco Stellacci at the Ecole Polytechnique Fédérale de Lausanne (EPFL) and Bartosz Grzybowski at Northwestern University has devised a simple, inexpensive s more
We propose a novel analytical method for mercury (Hg) trace determination based on direct Hg preconcentration from aqueous solution onto a gold nanoparticle-decorated silica monolith (AuNP@SiO2). Detection of Hg is performed after thermal desorption by means of atomic fluorescence spectrometry. This more
Mercury is toxic with widespread contamination. High sensitive and selective approaches for mercury analysis are desired. Although convention analytical techniques are accurate and sensitive in the determination of mercury, these procedures are time-consuming, labor-intensive and dependent heavily o more
Abstract: Mercury is one of the most toxic elements that may be found in natural water bodies and can negatively affect living organisms, human health as well as drinking water quality. In addition, water is the main transportation and transformation pathway of mercury into the environment and liv more
Mercury is undisputedly one of the most toxic elements. In 2013, the Minamata Convention on Mer-cury to restrict the production and emission of this heavy metal was adopted in Geneva. It regulates the production, use and storage of mercury. For example, new mines may no longer be built and existing ones must be closed within 15 years. more
