Abstract

In this work the systems were used, which do not require a special preparatory treatment in the process of adsorption of organic dyestuffs from water solutions. Three different types of organic dyestuffs were investigated: basic Basacrylrot GL, metal complex Lanasynrot 2BL and direct (substantive) dyestuff Solarrot B. As adsorbers, kaolin and two aluminium silicate natural mixtures with high content of amorphous silica were used. The adsorption was carried out isothermally at the temperature of 60 °C. The results were followed by spectrophotometry, by measuring pH of the filtrate and by determination of light radiation reflectance on DATACOLOR. All results were obtained by means of computer. The investigations showed that the temperature of 60 °C is suitable for the adsorption of organic dyestuffs on natural aluminium silicates (which is higher than that of 25 °C), so waste water clarifying by using adsorption in the textile dyeing plants can be recommended.
