Journal ArticleDOI
Characterization of chitosan with different degree of deacetylation and equal viscosity in dissolved and solid state - Insights by various complimentary methods.
Janek Weißpflog,David Vehlow,Martin Müller,Benjamin Kohn,Ulrich Scheler,Susanne Boye,Simona Schwarz +6 more
TL;DR: In this paper, the authors focused on the characterization of chitosan most important parameters, such as solubility, crystallinity, degree of deacetylation (DD) and molecular weight.
Journal ArticleDOI
Solubility and Selectivity Effects of the Anion on the Adsorption of Different Heavy Metal Ions onto Chitosan.
Janek Weißpflog,Alexander Gündel,David Vehlow,Christine Steinbach,Martin Müller,Regine Boldt,Simona Schwarz,Dana Schwarz +7 more
TL;DR: The adsorption capacity of the heavy metal ions manganese, iron, cobalt, nickel, copper, and zinc were investigated in dependence on their corresponding anions sulfate, chloride, and nitrate by batch experiments and the selectivity of the differentheavy metal ions was analyzed by column experiments.
Journal ArticleDOI
Hollow Au@TiO2 porous electrospun nanofibers for catalytic applications
Labeesh Kumar,Sajan Singh,Andriy Horechyy,Petr Formanek,René Hübner,Victoria Albrecht,Janek Weißpflog,Simona Schwarz,Puhup Puneet,Bhanu Nandan +9 more
TL;DR: In this paper, the authors reported the fabrication of catalytically active porous and hollow titania nanofibers encapsulating gold nanoparticles (AuNPs) using a combination of sol-gel chemistry and coaxial electrospinning technique.
Journal ArticleDOI
Investigation of mechanisms for simultaneous adsorption of iron and sulfate ions onto chitosan with formation of orthorhombic structures
Janek Weißpflog,Regine Boldt,Benjamin Kohn,Ulrich Scheler,Dieter Jehnichen,Vaclav Tyrpekl,Simona Schwarz +6 more
TL;DR: In this paper, the interaction of sulfate ions (SO42−) into the polymer chains of chitosan under acidic conditions was confirmed. And the results showed that the results correlate stoichiometrically with the adsorption behavior of iron and sulfate ion.
Proceedings ArticleDOI
Simultaneous Adsorption of Iron and Sulfate Ions with Biopolymers
TL;DR: In this article, the authors investigated the simultaneous adsorption of iron and sulfate ions onto a natural biopolymer, which was used to remove anions and cations from aqueous solutions.
