Analytical chemistry with biosolvents

One of the current trends in green analytical chemistry is the introduction of green solvents, some of which are biobased. At the same time, the development of the biorefinery concept has allowed more biochemicals to be obtained with increased efficiency and from a wider range of feedstocks. The first examples of the use of biosolvents in analytical applications included...

Novel Desorber for Online Drilling Mud Gas Logging

This work presents the construction solution and experimental results of a novel desorber for online drilling mud gas logging. The traditional desorbers use mechanical mixing of the liquid to stimulate transfer of hydrocarbons to the gaseous phase that is further analyzed. The presented approach is based on transfer of hydrocarbons from the liquid to the gas bubbles flowing...

Abiotic degradation of chlorinated ethanes and ethenes in water

Marek Tobiszewski Jacek Namienik Introduction Chlorinated ethanes and ethenes are among the most frequently detected organic pollutants of water. Their physicochemical properties are such that they

Determination of chlorinated solvents in industrial water and wastewater by DAI–GC–ECD

Marek Tobiszewski Jacek Namienik A very simple and quick analytical method, based on direct aqueous injection, for determination of halogenated solvents in refinery water and wastewater, is
