Abstract
The main aim of the presented work is to prepare surfactant-modified activated carbon and then use it to enhance the adsorption of some heavy metals and dyes from aqueous solutions. Study the effect of ions presence in aqueous solutions on the surface characteristics of surfactant-modified activated carbon. Study the effect of dyes on the critical micelle concentration of the surfactants in aqueous solution by electrical conductivity and spectroscopy methods. Study the thermodynamic parameters (ΔG ˚, ΔH ˚, and ΔS ˚) of the solvation process.
This thesis consists of three chapters.
The first chapter includes an overview of the definition, varieties, and general applications of surfactants and dyes. It also includes a brief overview of the commercial synthesis processes for the four surfactants that are the subject of the investigation (AOS, SLES, BAC, and CTAC). In addition to that, it includes an important section related to water sources, pollution, and methods of treatment. Adsorption of heavy metals and dyes by surfactant-modified activated carbon is considered one of the most common methods used in water treatment.
