Activated orange peels as an adsorbent was prepared by agitating in H2SO4 for 12 hours and washed with distilled water and again socked with2%NaHCO3 solution over night to remove excess acidity. It was calcined at a temperature of 350oC for 2:30 hours. Then the effect of adsorbent dosage, initial dye concentration, and contact time and particle size on the adsorption efficiency of the sample was tested using methylene blue as a target pollutant. The adsorption efficiency of the adsorbent for the removal of methylene blue was found as follows. adsorbent dosage and contact time was found to be directly proportional to the efficiency of adsorption of the prepared sample but up to a certain optimum value (82, 88.01 respectively) while initial dye concentration and particle size was found to be inversely related but still up to optimal amount or size.

Abstract
Activated orange peels as an adsorbent was prepared by agitating in H2SO4 for 12 hours and washed with distilled water and again socked with2%NaHCO3 solution over night to remove excess acidity. It was calcined at a temperature of 350oC for 2:30 hours. Then the effect of adsorbent dosage, initial dye concentration, and contact time and particle size on the adsorption efficiency of the sample was tested using methylene blue as a target pollutant. The adsorption efficiency of the adsorbent for the removal of methylene blue was found as follows. adsorbent dosage and contact time was found to be directly proportional to the efficiency of adsorption of the prepared sample but up to a certain optimum value (82, 88.01 respectively) while initial dye concentration and particle size was found to be inversely related but still up to optimal amount or size.
