Removal of Dark Blue-GL from Wastewater using Water Hyacinth: A Study of Equilibrium Adsorption Isotherm

The present investigation demonstrates that water hyacinth root is a potential adsorbent for the removal of dark blue-GL dye from wastewater by batch process. Various operating parameters such as the adsorption capacity, initial dye concentration, contact time, effect of pH, and adsorbent dosage wer...
