Sorption of As(V) from waters using chitosan and chitosan-immobilized sodium silicate prior to atomic spectrometric determination
Boyacı, Ezel; Shahwan, Talal (2010-01-15)
A natural biosorbent containing amine functional groups, chitosan, and a novel sorbent, chitosan-immobilized sodium silicate, were prepared and utilized for the selective sorption of As(V) from waters prior to its determination by atomic spectrometric techniques, namely, hydride generation atomic absorption spectrometry (HGAAS) and inductively coupled plasma mass spectrometry (ICP-MS). Chitosan was synthesized from chitin and sodium silicate was used as the immobilization matrix due to its straightforward s...

Sorption of BB41 dye molecules using chitosan based particles from aqueous solutions: A kinetic and thermodynamic evaluation
Demirtas, Hulya; Tasar, Seyda; Kaya, Fatih; Ozer, Ahmet (2022-08-01)
In this study, starting from chitosan is a hydrophilic polymer with positively charged, it was aimed to produce chitosan-based particles and to be evaluated as a sorbent. Chitosan-based polymeric particles production was carried out by the precipitation-collection method from chitosan. Chitosan and chitosan-based sorbent were characterized. For this purpose, SEM and FTIR analyzes were used. Sorption activities of the chitosan-based polymeric particles were investigated for basic dye (basic blue 41, BB41). T...
Sorption Efficiency of Chitosan Nanofibers toward Metal Ions at Low Concentrations
Horzum, Nesrin; Boyacı, Ezel; Eroglu, Ahmet E.; Shahwan, Talal; Demir, Mustafa M. (2010-12-01)
Chitosan fibers showing narrow diameter distribution with a mean of 42 nm were produced by electrospinning and utilized for the sorption of Fe(III), Cu(II), Ag(I), and Cd(II) ions from aqueous solutions. The ion concentrations in the supernatant solutions were determined using inductively coupled plasma-mass spectrometry (ICP-MS). The filtration efficiency of the fibers toward these ions was studied by both batch and microcolumn methods. High efficiency in sorption of the metal ions was obtained in the both...
