Removal of Congo red dye from aqueous solutions by a low-cost adsorbent: activated carbon prepared from Aloe vera leaves shell

ABSTRACT

Background: synthetic dyes have several harmful effects on human health as well as aquatic life. In this study, activated carbon [AV-AC], based on Aloe vera leaf shells, was used as a novel agricultural adsorbent, one that is low-cost and available for the removal of Congo red [CR] as a carcinogenic dye from aqueous solutions
