SEM and EDAX Study of Pretreated Rice Husk for the Sorption of Cu(II) from Wastewater

Abstract:

The morphological characteristics as well as important physical and chemical characteristics rice husks were evaluated by different techniques to analyze the suitability of rice husk to adsorb metal ions from water and wastewater. The raw rice husk (RRH), sodium carbonate treated rice husk (NCRH) and metal adsorbed rice husk were analyzed by SEM-EDAX study. Batch sorption kinetics studies were also conducted for Cu (II) to find the corresponding equilibrium time and the percentage removal for each of the experiment in the sorption process. The results of material characteristics and morphological aspects pointed out some properties that can make the sorption processes possible. The copper removal was observed in the range of 90 to 97 % depending upon the other physicochemical parameters of the sorption experiment. The highly efficient low cost and the rapid uptake by the proposed material indicated that it could be an excellent alternative for the removal heavy metal by sorption process.
