Langkam, Johny (2011) Removal of Chromium (VI) from water by using Lanthanum based Hybrid Materials. MSc thesis.
In various studies it is found that contamination of Chromium (VI) in water posed severe health problems throughout the world. Several methods are available to remove chromium from the aqueous environment but they are not feasible in all places and conditions due to various reasons. Some of the process are electrochemical precipitation, ion exchange, activated carbon adsorption, solvent extraction, reverse osmosis, etc., from contaminated water. The development of low cost adsorbent is essential for the benefit of the common people.
In this present work, Cr (VI) has been removed from water by a synthesized Lanthanum based hybrid material as adsorbent. The removal of fluoride was 98.50 % at optimum condition from the synthetic solution having initial Cr(VI) concentration of 100 mg/L The extend of adsorption was investigated as a function of solution pH, contact time, adsorbent concentration, reaction temperature, Langmuir and Freundlich isotherm were used to model the adsorption equilibrium data.
