It is still a challenge to disperse yellow iron oxides in organic media due to their susceptible aggregation, which limits their application in ceramic material area. In order to achieve colloidal stabilization in organic liquid, yellow iron oxides were dispersed in ethanol with p[methyl methacrylate-r-butyl methacrylate-r-N-(3-dimethylaminopropyl) methacrylamide] random copolymers (PMBAs) based on...
The adsorption of Ni(II) ions from aqueous solution by chitosan (CTS) and its triethylenetetramine derivative beads (CCTS) was investigated in a batch adsorption system. Chitosan beads were crosslinked with epichlorohydrin and then grafted with triethylenetetramine to obtain sorbents that are insoluble in aqueous acidic solution and improve adsorption capacity, respectively. Elemental analysis, scanning...
To understand the relationship of molecule structure and dispersion mechanism, the influence of linear polycarboxylate-type superplasticizers on the adsorption properties and rheological behavior of ceramic suspension were carried out in this study. Experiments, measuring the static and dynamic viscosity of different polyelectrolytes and their rheological behavior in concentrated ceramic slurry, were...
