Removal of Reactive Orange 13 (RO13) onto Rice Husk in Aqueous Solution

The present study shows that rice husk which is easy to get can be used as a low-cost adsorbent. Rice husk can remove harmful ReativeOrange13 (RO13) from aqueous solution. In dyeing industries RO13 is used in a large quantity and when those industries dispose the untreated effluent to the open water it creates serious water pollution. Rice husk can remove the dye staff from the aqueous solution and may help to keep water comparatively clean and safe. This study helps to know that rice husk as natural adsorbent can remove dyes by adsorption process and the process was endothermic in nature. Adsorption process was spontaneous too. Experimental data shows the nature of adsorption was physical in type and feasible. Key Words: Adsorption; Adsorbent; Reactive Orange 13; Removal; Spontaneous;
