Removal of Dyes from Dye Effluent by Using SugarcaneBagasse Ash as an Adsorbent

Sugar cane bagasse ash, an agricultural byproduct,acts as an effective adsorbent for the removal of dyesfrom aqueous solution. Batch adsorption study wasinvestigated for the removal of Acid Orange-II from aqueoussolution. Adsorbents are very efficient in decolorized dilutedsolution. The effects of bed depth on breakthrough curve,effects of flow rate on breakthrough curve were investigated.The removal of dyes at different flow rate (contact time), bedheight, initial dye concentration, column diameter, pH &temperature by Sugarcane Bagasse Ash as an adsorbent hasbeen studied. It is found that percent adsorption of dyesincreases by decreasing flow rate from 2 lit/hr to 1 lit/hr, byincreasing bed height from 15cm to 45cm, by decreasing initialconc.150mg/lit to 100mg/lit, by increasing column diameterfrom 2.54cm to 3.5cm,by maintaining neutral pH & attemperature 45 super(o)c than 25 super(o)c & 35 super(o)c.The result shows that,bagasse ash is a good adsorbent for dye effluent treatment.
