Electrospun polystyrene/Aliquat 336 for preconcentration and determination of thiocyanate in flow analysis

Abstract

Abstract:A new extracting polymer wool was prepared from polystyrene (PS) and the commercial extractant Aliquat 336 by electrospinning and its potential as a packing material for an online preconcentration column in an automated flow injection system was investigated for the determination of thiocyanate (SCN − ). The formation of the wool fibres was confirmed by scanning electron microscopy (SEM). The polymer wool was inserted into a glass tube to prepare a column. a sampling rate of 9 h −1 . To the authors' best knowledge this is the first time electrospun fibres containing a liquid extractant have been used for preconcentration in a flow analysis system.

Microfluidic Fabrication of Micropolymer Inclusion Beads for the Recovery of Gold from Electronic Scrap

“…23 PIMs are difficult to incorporate into separation columns unless they are cast onto the surface of the column packing (e.g., glass beads) and/or onto the internal walls of the column. 29 Alternative approaches have been based on packing a separation column with polymer inclusion wool fabricated by electrospinning 30 or PIM strips. 31 In a recent paper, we reported on the development of a novel microfluidic technique for the fabrication of polymer microspheres (microbeads).…”

First Report on a Solvent-Free Preparation of Polymer Inclusion Membranes with an Ionic Liquid

“…The IL trioctylmethylammonium chloride (Aliquat 336) is widely used to produce membranes due to its versatility and affordability, and has successfully been employed as a cation source of a new family of hydrophobic ILs [10]. Its ability to extract anionic species has been exploited in several studies concerning either inorganic [11,12,13,14,15] and organic compounds [16,17].…”
