Characterisation of pigments obtained by adsorption of C.I. Basic Blue 9 and C.I. Acid Orange 52 dyes onto silica particles precipitated via the emulsion route
چکیده انگلیسی
The adsorption of C.I. Basic Blue 9 and C.I. Acid Orange 52 dyes onto the colloidal silica surface precipitated via emulsion route was investigated in an aqueous medium. Equation of Berendsen and de Golan permitted to establish adsorption isotherms on the basis of chemical composition of the studied substances. Using direct measurements of zeta potential as a function of pH, electrokinetic characteristics were estimated for the studied silica carriers and the obtained pigments. The performed studies on dispersion demonstrated that the produced organic-inorganic hybrid systems manifested a highly homogenous character and a relatively low tendency to form agglomerate structures. In addition, the studied pigments were subjected to a comprehensive colorimetric appraisal using the CIE L*a*b* colour space system.
