Removal Of Methylene Blue Dye From Aqueous Solutions By Neem Leaf And Orange Peel Powder

The objective of this work is the study of adsorption of dye solutio n methylene blue using low cost adsorbent like neem leaf and orange peel powder. Liquid phase adsorption experiments were conducted. Batch adsorption studies are carried out by observing the effect of experimental parameters, namely amount of adsorbents, dye concentration and contact time. Optimum conditions for dye removal are studied like contact time required, amount of adsorbent and dye concentration. Spectrophotometric technique was used for the measurement of concentration of dye before and after adso rption. The removal data were fitted on Langmuir adsorption equations. The equilibrium time was found to be 18 min for 2.5×10 -5 mg/L dye concentration respectively. A maximum removal of 90-95% was obtained for an adsorbent dose of 0.3 gm. at 2.5×10 -5 mg/L dye concentration The results generated by this work can be used for determination of optimum conditions for adsorption of dye in aqueous solutions. Dyes are present in mixture form in various Industrial effluents like Textile Industries, Sewage water, Water treatment plants. This work could have use in Design of adsorption columns for dye removal.
