Potential of cellulose acetate for the removal of methylene blue dye from aqueous streams

Abstract

In present study adsorption behavior of Cellulose Acetate for removal of Methylene blue has been studied in a batch wise mode. Adsorption experiments were conducted using 100 ml of dye solution (10ppm), pH (2-9) and adsorbent dose (0.5-2.0 g) at 150 rpm at 25oC. Rate of decolonization was estimated from residual concentration spectrophotometrically. The experimental results indicated that cellulose Acetate can effectively remove 60% dye from aqueous streams. The high decolorizing efficiency was obtained with 1.0 g/l of adsorbent dose. Cellulose Acetate was characterized by using FTIR Fourier transform infrared spectroscopy analysis and SEM Scanning electron microscopy analysis.
