Detailed characterization (HRSTEM, STM, and N 2 adsorption) was performed, followed by active carbon soaking in iron and manganese ionic solutions obtained from remediated mining sludge. Novel forms of active carbons with round or needle-like oxide particles on the surface were obtained by combining these materials. The materials were tested as filters for sulfur dioxide, on sulfur-rich coals fume. After adsorption, the iron structures seem to play a stronger catalytic role in the filter regeneration, transforming the adsorbed sulfur dioxide into sulfuric acid. © 2018 Elsevier Ltd.

Introduction In today’s society high demand and consumption of energy has caused serious pollution of air, soil and water. The sources of pollution are fossil fuels, industries, traffic, agriculture and many other human activities, but regardless of its origin the consequences of human reluctant behavior are getting more and more apparent as well as * Corresponding author.
