Abstract

Textile dyes are one of the wastewater contaminants. Treatment of industrial wastewater considers a challenge when choosing effective approaches. Adsorption on activated carbon is one of the superior techniques were evaluated in previous studies and considered in this thesis. In practice, the adsorption capacity of the active sits on the carbon was high. Consequently, activated carbon was used to remove textile dyes (Dylon Yellow) from wastewater under different parameters that may affect the adsorption of reactive dye. In principle, the influence of various factors such as dye type, carbon type, contacting time between carbon and dye solutions, pH, and salinity was investigated. Minitab software was used to design the experiment and evaluated to determine the significance of each factor. As a result, this work has showed that pH and salinity has no impact on the adsorption process. However, this study confirmed the previous results of influencing of dye type, carbon type and contacting time between dye solutions and carbon on the adsorption of reactive dye on activated carbon. Increasing the contacting time between carbon and dye solution allows the carbon to absorb larger amount of dye. Further, variation of carbon type or dye type plays an important role in influencing the ability of carbon to absorb dye.
