Adsorption of Amaranth Dye from Aqueous Solution Using Environmental Friendly Biosorbents-eggshell Powder.

Background And Objective: Dyes and pigments have been used in many industries for coloration purpose but they pose hazards to environment and end users of water. Therefore, it is important to remove these pollutants from wastewater before their final disposal. This work aimed to investigate the removal of amaranth dye by cost effective, eco-friendly, highly efficient adsorbents such as egg shell powder and environmental friendly biosorbent.
