Matlab Based Kinetic And Isotherm Analysis For The Recovery Of Chromium (Vi) And Lead (Ii) Using Ulva Fascia

Generation of industrial wastes has significant contribution in altering the contents of water to a greater extent. Of these wastes, heavy metals are a major class with the challenge of non degradability by any means. Hence the safer disposal by removing them using indigenous method is essential. In this perspective, an attempt has been made to recover chromium and lead from dilute solutions by adsorption method. Ulva fascia, a marine algae has been used as a sorbent in protonated form to recover the metal ions. Under optimum pH, agitation rate and sorbent size and dosage for each of the metals, a maximum removal percentage of 97 and 94 were observed for chromium and lead respectively. The corresponding metal uptakes were 32.3 and 58.75 mg/g respectively. The kinetic studies revealed that sorption pertained to Lagargren First order kinetics and the isotherm studies proved the validity of Redlich Peterson model for the two metals.
