Influence of frequency on specific conductance of polyelectrolyte gels with special correlation between strength of chelation and stability of divalent metal alginate ionotropic gels

Kinetics of Corrosion Inhibition of Aluminum in Acidic Media by Water-Soluble Natural Polymeric Pectates as Anionic Polyelectrolyte Inhibitors

“…In view of the above arguments and our interest in physicochemical properties of macromolecules, in particularly the natural polymeric compounds [23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46], the present work was undertaken to shed more light on the role of the nature of medium and the structural geometry of the inhibitor on the corrosion process. The study also aimed to elucidate a suitable mechanism for corrosion of Al in acidic medium and discuss the results in comparison with previously reported studies on use of the natural polymer pectate polysaccharide as inhibitor for corrosion of Al in alkaline solutions [16].…”

A Revisit to the Corrosion Inhibition of Aluminum in Aqueous Alkaline Solutions by Water-Soluble Alginates and Pectates as Anionic Polyelectrolyte Inhibitors

“…In view of the above arguments and our interest in physicochemical properties of macromolecules in particularly biodegradable and nontoxic polysaccharides [22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38], the present work seems to merit a further reinvestigation with the aims at shedding more highlights on the corrosion behavior in terms of fitting the kinetic data to the adsorption isotherm models. Furthermore, this study aims to throw some light on the role of the functional groups 2 International Journal of Corrosion and geometrical configuration of the inhibitors used in the adsorption process as well as the influence of the nature of the medium on the corrosion mechanism.…”

Polymeric biomaterial hydrogels. I. Behavior of some ionotropic cross-linked metal-alginate hydrogels especially copper-alginate membranes in some organic solvents and buffer solutions

“…In view of the aforementioned aspects and our interesting on studies of physicochemical properties of some metal-alginate hydrogel biomaterials [15][16][17][18][19][20][21][22][23][24][25], the present work seems to be of interest with the aims at shedding further highlights on the behavior of metal-alginates par-ticularly copper-alginate gel membranes in various solvents and buffer solutions and to compare the results obtained with that reported for calcium-alginate spheres in both aqueous [3], and in non-aqueous solutions.…”
