Title:Central Composite Design for Optimization of Chromium (VI) Removal from Aqueous Solution Using Low Cost Adsorbent
Author Name:D. Krishna and D.V. Padma
Synopsis:
Aim of the experiment is to find out the optimization of adsorption parameters such as initial chromium (VI) concentration (5-30 mg/l), pH (1-4), and adsorbent dosage (1-3 g/l) using Central Composite Design in response with surface methodology. A total of 19 experiments were conducted for the present investigation towards construction of empirical model. The optimum conditions for maximum removal of chromium from an aqueous solution of 20 mg/l were as follows: adsorbent dose (2.26806 g/l), pH (1.76296) and initial chromium concentration (24.99465 mg/l). The maximum percentage removal of chromium at an optimum adsorption parameter is 70.53756%. This method is used to find out the mathematical model for the percentage removal of chromium metal ion from waste water efficiently.
