Abstract :

Activated carbon with nano hole made of lemon is called GA-88 in this research. Using nano technology in the way of decreasing effects of polluting environment and wastewater of industrial factory including water plays important role and has high efficiency. In this research ability of GA-88 absorbent with nano hole for elimination of phenol has been studied. Chemical optimization of nano absorbent GA-88 has been performed by using acid phosphoric with densities 10% and 15%. Then effective factors for absorbing phenol, effect of change in pH at range of 2 to 12, time of duration until 15 to 75 minutes was exactly studies and assessed. Change in pH at lower than 7 was very effective on ability of absorption so that under pH=2 and pH=12 intensity of absorption 99.125% and 63.1% and absorption capacity 19.825% and 12.62%mg phenol /gr GA-88 /liter respectively. Time of optimization for eliminating phenol with density of 200mg/liter and 800mg/liter was at first 15 minutes. In this process the quasi second grade speed equation in comparison to quasi first grade speed equation, GA-88 nano absorbent with fixed speed is suitably defined as 5.12 x 10-3 mg-1.min-1 and 2.35mg x 10-3 for density of 200mg/liter and 800mg/liter. In order to describe balance of absorption it is used from Longmuir and Freunlich models. Results indicate that Longmuir model for both densities of 200mg/liter and 800mg/liter is more valuable than Freunlich model and R2 amount related to Longmuir was 1 and 0.999 was achieved respectively
