RETRACTED ARTICLE: Carbonization, Impregnation and Activation Synthesis for Sulfur Dioxide Adsorbent Capacity of Carbon

Abstract

Activated carbon is one of the important and widely used porous materials for removal of pollutants from gas streams or liquid solutions. One of the important parameters in determination of quality of activated carbon as an adsorbent material is the capacity for removal of pollutants. The removal capacity of activated carbon is directly proportion to impregnation ratio, carbonization temperature, carbonization time, activation temperature and activation time in synthesis process. In this study the optimum of these processing parameters in synthesis of activated carbon in order to reach the maximum capacity for removal of SO2 as a challenge gas was determined. Series of activated carbon samples was synthesized under different processing parameters as impregnation ratio, carbonization temperature, carbonization time, activation temperature and activation time. Samples were tested for SO2 removal according to ANSI/ASHRE standard 145.1 (2008). Results showed that the maximum total capacity for removal of activated carbon and for removal of as a challenge gas at optimum processing parameters was 1.4 × 10−4 % mass.
