The oxygen-containing functional groups and pore structures of activated carbon in adsorption and oxidation mechanism of hydroquinone were studied. Effects of initial pH value

the dosage of activated carbon

on the adsorption and oxidation efficiency of hydroquinone were studied. Then the relationship between adsorption rate

apparent conversion rate of hydroquinone and the materials of activated carbon

the dosage of activated carbon was discussed. The results showed that the oxygen-containing functional groups of activated carbon could adsorb and oxidate hydroquinone

wood-chip activated carbon was better than the other two types of activated carbon on the adsorption and oxidation efficiency of hydroquinone. Under the condition of not to adjust the initial pH

reaction time 3 h

and reaction temperature 25℃

if wood-chip activated carbon dosage was 0.5 g·L-1 quality its base adsorption was 95.5% and if dosage was 0.1 g·L-1 the conversion of hydroquinone was 32.1%. The microporous surface area of sawdust activated carbon was larger than the other two activated carbon's

and the phenol hydroxyl group

carboxyl group

and carbonyl group were more abundant. Therefore

the adsorption and oxidation efficiency of hydroquinone using sawdust activated carbon was better. On the basis of this

the mechanism of activated carbon adsorption and oxidation of hydroquinone were proposed. It provided the theoretical basis for the treatment of wastewater containing phenolic organic pollutants by activated carbon as adsorbent and catalyst carrier.
