Pyrrole-Based Composites for Metal Extraction and Analysis

Description:

Project ID:  D2018-19

 

Invention Description

The researchers at the University of Toledo have developed a sorbent coating that allows for direct extraction of metal ions without need for derivatization. These composite-coated pencil leads may be used as extraction fibers for solid-phase microextraction of metal ions. Further sensitivity and selectivity can be accomplished with inductively coupled plasma-mass spectrometry. This invention can also be scaled for solid-phase extractions. SPE and SPME applications coupled with the sorbent coating can assist in quantitative extractions and trace analysis in complex matrices.

 

Applications

•       Selective microextraction devices

•       Water purification systems

 

Advantages

•       Tunable selectivity based on the chelating agent

•       Cost effective materials 

•       No need for derivatization step

•       Environmentally friendly
