Journal ArticleDOI
Application of the zeta potential measurements to explanation of colloidal Cr2O3 stability mechanism in the presence of the ionic polyamino acids
TL;DR: Determination of the stabilization/destabilization mechanism of the polyamino acid/chromium (III) oxide system and examination of the effects of polymer molecular weight on the stabilization properties can contribute to a wider use of this group of compounds as potential stabilizers or flocculants in many industrial suspensions.
Journal ArticleDOI
Investigation of the polyvinyl alcohol stabilization mechanism and adsorption properties on the surface of ternary mixed nanooxide AST 50 (Al2O3-SiO2-TiO2).
Małgorzata Wiśniewska,Iwona Ostolska,Katarzyna Szewczuk-Karpisz,Stanisław Chibowski,Konrad Terpiłowski,Vladimir M. Gun’ko,Vladimir I. Zarko +6 more
TL;DR: The stability measurements indicate that the AST 50 suspensions in the presence of the background electrolyte at pH 3 and 6 are unstable; in an alkaline medium the mixed oxide suspensions exhibit the highest durability, which is a result of a large number of the negative charges on the AST50 surface.
Journal ArticleDOI
Nanostructure of Poly(Acrylic Acid) Adsorption Layer on the Surface of Activated Carbon Obtained from Residue After Supercritical Extraction of Hops
Małgorzata Wiśniewska,Agnieszka Nosal-Wiercińska,Iwona Ostolska,Dariusz Sternik,Piotr Nowicki,Robert Pietrzak,Aleksandra Bazan-Wozniak,Olena Goncharuk +7 more
TL;DR: The nanostructure of poly(acrylic acid) (PAA) adsorption layer on the surface of mesoporous-activated carbon HPA obtained by physical activation of residue after supercritical extraction of hops was characterized using the SEM, thermogravimetric, FTIR, and MS techniques.
Journal ArticleDOI
Investigations of the possibility of lithium acquisition from geothermal water using natural and synthetic zeolites applying poly(acrylic acid)
Małgorzata Wiśniewska,Gracja Fijałkowska,Iwona Ostolska,Wojciech Franus,Agnieszka Nosal-Wiercińska,Barbara Tomaszewska,Joanna Goscianska,Grzegorz M. Wojcik +7 more
TL;DR: In this article, the authors investigated the possibility of obtaining lithium from geothermal water using natural and synthetic zeolites applying poly(acrylic acid) and found that the amount of adsorbed lithium ions increases with the increasing pH value of the solution.
Journal ArticleDOI
Adsorption of poly(acrylic acid) on the surface of microporous activated carbon obtained from cherry stones
Małgorzata Wiśniewska,Piotr Nowicki,Agnieszka Nosal-Wiercińska,Robert Pietrzak,Katarzyna Szewczuk-Karpisz,Iwona Ostolska,Dariusz Sternik +6 more
TL;DR: In this article, the adsorption properties of microporous activated carbon (CSDA) obtained by direct activation of cherry stones in relation to low-molecular weight poly(acrylic acid) − PAA were examined.
