Chemical Fractionation in Environmental Studies of Potentially Toxic Particulate-Bound Elements in Urban Air: A Critical Review [PDF]
In recent years, studies of heavy metal air pollution have increasingly gone beyond determining total concentrations of individual toxic metals. Chemical fractionation of potentially toxic elements in airborne particles is becoming an important part of ...

Modification of the NH2 column method for chromium speciation in surface water and soil water [PDF]
A new application of the NH2 column method has been tested for speciation of Cr(VI) in soil water and surface water. Soil water and surface water samples were collected from two sites near the world’s largest stainless steel production plant, Outokumpu ...

Nitrogen isotopes in the interstellar medium: A chemical journey across the Galaxy [PDF]
One of the most important tools to investigate the chemical history of our Galaxy and our own Solar System is to measure the isotopic fractionation of chemical elements. This is the process that distributes the less abundant stable isotopes of an element

Using hydrocyclone fractionation to improve chemical pulp quality
Production of chemical pulp is accompanied by various impurities in addition to the cellulose fibres produced. The impurities are mainly due to lignin fragments and wood resin components in the wood.
