Alkali-modified activated carbon is used as an efficient adsorption material for the purification of SO2 in the clean room of semiconductor industries and data centre.However，there are few low?concentration SO2 adsorption experiments and model studies that conform to the real building environment.The adsorption performance of three alkali?modified activated carbons，namely copper oxide?potassium hydroxide modified activated carbon，potassium hydroxide modified activated carbon and magnesium hydroxide modified activated carbon，at a temperature of 25 ℃，a relative humidity（RH） of 50% and SO2 mass concentration of 2 612 mg/L was firstly investigated.The results showed that the adsorption capacity of the alkali?modified activated carbon samples to SO2 was more affected by the alkali load.The experimental values of the adsorption isotherm curves of activated carbon loaded with potassium hydroxide?copper oxide were then measured at SO2 mass concentrations ranging from 522 to 13 400 mg/L.The validity of the Langmuir model，Freundlich model and Dubin?Radushkevich（D-R） model was verified，with the Freundlich model fitting best at low concentrations（SO2 mass concentration of 522 mg/L，error -12.18%）.The experiments on alkali?modified activated carbon at a sulphur dioxide mass concentration of 2 612 mg/L and different RH（1%，50% and 75%） showed that increased RH promoted the adsorption of sulphur dioxide on the samples surface.Analysis of the modified activated carbon by fourier transform infrared spectroscopy showed that the absorbents on the surface of the samples were —SO3（or SO42-） and —SO2.X-ray photoelectron spectroscopy showed that the S6+ form was accounted for 80% to 90% and the proportion was increased with the increase of RH.The alkali?modified activated carbon eventually adsorbed gaseous SO2 in the form of SO42- and the adsorption process was dominated by chemical adsorption.
