Uptake of Indosol Dark-blue GL Dye from Aqueous Solution by Water Hyacinth Roots Powder: Adsorption and Desorption Study

Adsorption characteristics of water hyacinth roots powder for the removal of Indosol Dark-blue GL dye were investigated in batch mode. Operating variables, such as initial solution pH, presence of detergent, adsorbent dosage, initial concentration and contact time, were studied. The results showed t...
