Studies were performed on cleaning the solutions contaminated with organic dyes. Silica modified with the aminosilane coupling agent was used for the adsorption of the dyes. The procedure was followed by the estimation of the extent to which the dye was removed from the contaminated solution. In the obtained pigments, the particle size distribution, the tendency to form agglomerates as well as the particle surface morphology, were examined using the SEM and DLS techniques.
