Present study deals with the adsorption of textile dye from aqueous solution on commercial activated carbon. The adsorption of Procion 072 Medium Blue dye on carbon was assessed by measuring absorbance using a UV-Vis spectrophotometer. The main goal of this research was to understand the nature of the interaction between adsorbed molecules of the dye by activated carbon under various conditions of pH, Salinity, time and types of Carbon. Results of this research showed good correlation with the Langmuir isotherm model. Factors that could affect the adsorption were assessed. Significant influence on adsorption was found in contact time, type of carbon and type of dyes. Salinity of water and pH on other hand showed negligible influence on adsorption of the dye. Minitab 16® Software was applied to design the experiments and to identify the significance of each factor. Furthermore, it was generated the randomized run orders for the experiments. A factorial experiments has five factors, three factors Carbon type, Dye type and pH with 3 levels, and two factors time and salinity with 2 levels, also it has 216 experimental conditions. Present research showed activated carbon is suitable natural adsorbents for removing dyes from wastewaters in textile industry.
