Abstract :

In this study, the experiments were performed to find the adsorption capacities of locally available Water Hyacinth (W.H.) which are waste for rivers, ponds and lakes. Water creates problems for navigation and recreation also, these we have used Water Hyacinth as adsorbent. This adsorbent is also used to remove the colour of Acid Blue-7 dye which is used in textile industry. Experiments were conducted with different parameters like adsorbent dosage, pH, temperature and contact time using adsorption Isotherms method. The adsorption isotherm of the Acid Blue-7 on the treated adsorbent was determined and correlated with common isotherm equations. The sorption data were then correlated with the Langmuir and the Freundlich adsorption isotherm models. The Langmuir isotherm exhibited a better fit for the adsorption data than the Freundlich isotherm with maximum monolayer adsorption capacity of 12.5 mg g–1. From the experimental investigations, the maximum colour from the wastewater was obtained at an optimum adsorbent dosage of 50 mg in an optimum contact time of 4 Hrs.
