AI Article Synopsis
- The study examines how the structure of carbon materials affects their ability to adsorb certain cationic dyes, including Basic Violet 3, Basic Red 1, and Basic Blue 9.
- Various techniques, such as scanning electron microscopy and nitrogen adsorption, were used to analyze the carbon's structure and surface properties.
- The results suggest that these carbons are effective adsorbents due to their uniform spherical shape and diverse pore sizes suitable for trapping larger dye molecules.
Article Abstract
The influence of carbon pore structure on the sorption process of selected cationic dyes has been investigated. The structure and surface of carbonaceous materials have been characterized basing on various techniques: scanning electron microscopy, low temperature nitrogen adsorption-desorption measurements, X-ray photoelectron spectroscopy and thermal analysis combined with identification of gaseous products. The kinetic and equilibrium adsorption measurements of Basic Violet 3, Basic Red 1 and Basic Blue 9 from aqueous media were performed. The studied carbons seem to be promising adsorbents towards dyes, taking into account the easy-to-use uniform spherical form of the granules and a complex type of porosity with micro-, meso- and macropores appropriate for large molecule adsorption.
