Synthesis of Polyacrylaminothiourea Chelating Fiber and Properties of Concentration and Separation of Trace Noble Metal Ions from Samples

Abstract

KcprwQ concentration, separation, polyecxylacylamkm thiourea chelating fiber, gold, plahnum, palladium, iridium ( lV) ions from aqueous solution sample, as m e a s u r e d by inductively-coupled plasma atomic emission spectrometry (ICP-AES) , were studied in detail. Good precision and the accuracy of the pmpoeed method could be achieved by analysis of a real aqueous sample and a powder sample with satisfactory results.

Modified Pet Fibres for Metal Ion and Dye Removal from Aqueous Media

“…Several studies have been done to produce chelating or ion exchange fibres from raw acrylic fibres [5][6][7][8][9] . We also used different methods to modify acrylic fibres to prepare metal ion chelating fibres in our previous studies [10][11][12][13][14][15] .…”

Fabrication of chelating diethylenetriaminated pan micro and nano fibers for heavy metal removal

“…In another study [15], a polyacrylaminothiourea chelating fiber has been synthesized for removal of Au(III), Pt(IV), Pd(IV) and Ir(IV) ions from solution.…”
