Waste glass: An excellent adsorbent for crystal violet dye, Pb2+ and Cd2+ heavy metals ions decontamination from wastewater
The suitability of waste glass as an eco-friendly adsorbent for the removal of crystal violet (CV) dye, Pb2+ and Cd2+ heavy metal ions in waste water samples was investigated in batch mode. Waste glass sample was pulverized and characterized by SEM/EDX, XRD, BET and FTIR. Effects of variation in te...
