Preconcentration of trace metals with dithiocarbamate-chitin.

Preconcentration in Inorganic Trace Analysis

Preconcentration in trace analysis lowers the detection limit, simplifies the treatment of a representatIve sample, facilitates calibration, reduces the need for various standard reference samples and frequently involves separation of the matrix in analysis of toxic, radioactive and expensive materials. In this paper, the types of preconcentration are considered and quantitative characteristics...

Sampling and Preconcentration for Trace Explosives Detection

A trace explosives detection system typically contains three subsystems: sample collection, preconcentration, and detection. Sample collection of trace explosives (vapor and particulate) through large volumes of airflow helps reduce sampling time while increasing the amount of dilute sample collected. Preconcentration of the collected sample before introduction into the detector improves the se...

The Complexes of Antibiotics with Trace Metals

The term antibiotics [Gr. anti against, bios life] refers to a group of organic natural chemical compounds produced by such microorganisms as: bacteria, actinobacteria, warious types of fungi and some plants and animal cells. Many substances isolated from these organisms are synthesized on an industrial scale as a whole (of synthetic origin, called chemiotherapeutics) or in part (of semisynthet...

Chitin Adsorbents for Toxic Metals: A Review

Wastewater treatment is still a critical issue all over the world. Among examined methods for the decontamination of wastewaters, adsorption is a promising, cheap, environmentally friendly and efficient procedure. There are various types of adsorbents that have been used to remove different pollutants such as agricultural waste, compost, nanomaterials, algae, etc., Chitin (poly-β-(1,4)-N-acetyl...
