Studying the process of blue methylene removed from waste water using modified bentonite clay

Abstract

There is definitely a need to improve the absorption capacity of naturally available bentonite against water pollutants such as the methylene blue pigment (MBD). For this purpose, bentonite clay was modified in our study by adding hydrochloric acid to remove the MB tincture from industrial waste. Batch adsorption tests were performed to remove MBD from an aqueous solution using modified bentonite. It was found that the effectiveness of bentonite against MBD removal was when using modified bentonite by adding HCl (0.2, 0.4,0.6) M. XRD, XRF, Surface Area analysis showed that the increase in the bentonite microscopic plates over HCl treatment was the reason for MBD's high absorption. The increase in the concentration of hydrochloric acid leads to changes in the surface area which are due to structural change and partial disintegration of the Sample, The increase in the sorbent concentration or the initial pH value of the solutions resulted in greater MBD removal from the solution.
