Use of Natural Material – Clay for Sustainable Treatment of Water Polluted By Dyes
Journal Title: International Journal of Engineering and Science Invention - Year 2017, Vol 6, Issue 9
Abstract
Apart from the colorful side of dyes, the harmful effects they impose on environment cannot be overlooked. Treatment of water containing these dye effluents is todays demand. For encouraging methods that are sustainable for the desired purpose, use of natural materials like clay is suggested. Clay treated with acid called as acid activated clay (AAC) are efficient adsorbents when adsorption is chosen among other methods. Characterization of AAC was done using EDX, XRD, FTIR and SEM. Specific surface area and pore size determinations were also done. To test the efficiency of AAC for removal of BV2 dye from aqueous solution was done by varying different parameters. It was found that % removal increased from 78.77 % to 98.14 % for increasing dye concentration. Best adsorbent dose was found to be 0.05 gm. Alkaline pH favors the adsorption of basic dye. Rate of adsorption was in good correlation with pseudo second order kinetics. Adsorption mechanism was governed by surface diffusion as predicted from IPD and Boyd kinetic models. Surface morphological studies using SEM and FTIR shows changes in surface of adsorbent after adsorption. From the present study, it is suggested that acid activated clay can be effectively used as adsorbent for sustainable development of society.
