摘要: Purpose – The purpose of this paper is to characterise the electrokinetic properties pigments supported on both unmodified and modified silica. describes preparation hybrid via adsorption organic dyes silica supports determination zeta potential electrophoretic mobility materials obtained.Design/methodology/approach studied were obtained as a result two basic dyes: C.I. Basic Red 1 Orange 14 one acidic dye Mordant 3 from solutions concentrations 500, 2,000 3,000 mg/dm3 surface supports. agent used for modification was N‐2‐(aminoethyl)‐3‐aminopropyltrimethoxysilane.Findings with aminosilane found change, significantly, character inorganic support. This change interpreted being due ionisation −NH2 groups f...
