摘要：

The adsorption isotherms for 2,4,6-trinitrophenol (picric acid) on five samples of coconut-based activated carbons (ACs) with varying surface area have been studied. The results obtained show that adsorption depends upon surface area but is not linearly related to it. The adsorption increases on oxidation with ammonium persulphate ((NH4)(2) S-2 O-8) as well as on degassing at 600 degrees C. The results have been explained on the basis of the existence of surface carbonyl groups, where the O-2 Of the carbonyl group interacts with pi electrons of the benzene ring of picric acid.
