DYE ADSORPTION USING PLANT LEAVES POWDER Introduction Result

DYE ADSORPTION USING PLANT LEAVES POWDER Introduction Result And Discussion q Adsorption of Red coloured effluent were found to be more effective with neem and cabage leaves. Adsorption is an eco friendly and non destructive method of dye removal from water samples. It is reported that 10 to 15% of dyes are lost in the effluent during the process. Azo dyes have been used increasingly in industry because of their ease and cost effectiveness in synthesis as compared to other natural dyes.

(A) For Lotus leaves : - q Lotus leaves were collected from the vicinity of Kashid Beach near Alibaug. q These collected leaves were washed with distilled water, air dried for 24 hours in static condition. After drying process, leaves were ground to fine powder and sieved through 600 micron sizes. q This was then treated with 0. 5 N concentrated H 2 SO 4 followed by heat treatment at in an oven.
