| Background and Aim: Nowadays, removal of pollutants from water resources is a matter of concern in environmental sciences. Colors in addition to its negative impact on the aesthetic aspects have serious chemical and biological negative effects on the environment. Considering their resistance to heat, light and chemicals, they are not disintegrated easily in the environment. So this type of pollutants must be refined before pouring into the environment. Colors are used in paper, plastics and cosmetic industries and their effluent can contaminate surface and groundwater. The aim of this study was to evaluate the efficiency of modified garlic pods in the removal of cationic blue 41 from aqueous media in batch systems.
Material and Method: In this experimental - laboratory study- at first we prepared garlic pods. The optimum pH was determined under stable conditions. Then initial concentration of adsorbent, contact time and different concentrations of dye were assessed at optimal pH level. Using Excel software, data analysis was performed by means of regression coefficient.
Result: The results revealed that the maximum cationic dye removal occurred at neutral pH. By increasing the dye concentration elimination of the dye decreased. Also we found that the efficiency of dye removal improved by increasing contact time and adsorbent concentration.
Conclusion: Adsorption is a highly efficient method for removal of color, odor, organic and inorganic substances from wastewaters in different industries. Garlic pod is cheap and available and can be used as an adsorbent for removal of dyes from wastewaters in the textile industries.
