Abstract
The sorption of sulfur dioxide from the air by the fibrous anion exchangers containing amino groups of different structure and basicity has been comparatively investigated. The most effective sorbents of sulfur dioxide are the anion exchangers with ternary amino groups, which have a high exchange capacity (more than 5 meq/g) and additionally contain secondary amino groups. The anion exchangers with high-base amino groups absorb sulfur dioxide at low relative humidity (30 %) but have low dynamic sorption capicity (up to 1.3 meq/g). The anion exchangers with primary and secondary amino groups absorb sulfur dioxide at high relative humidity (more than 54 %) if their cation exchange capacity is several times less than the anion exchange capacity.
