Abstract

The invention discloses novel sulfur dioxide adsorbent, prepared from, by weight, 10-20 parts of activated carbon, 8-10 parts of sodium carbonate, 8-10 parts of sodium bicarbonate and 5-10 parts of zeolite powder, 5-10 parts of ferric chloride, 8-10 parts of sodium percarbonate, 8-10 parts of citric acid, 3-5 parts of sodium hypochlorite, and 20-30 parts of water. Compared with existing technology, the invention has the following beneficial effects: 1, the invention cannot only have stronger effect of removing sulfur dioxide, but also greatly decrease air pollution index; 2, the preparing technology is relatively simple and cost is low.

Description

technical field [0001] The invention relates to the field of environmental protection. More specifically, the present invention relates to a novel sulfur dioxide adsorbent. Background technique [0002] Sulfur dioxide (chemical formula SO 2 ) is the most common and simplest sulfur oxide. One of the main air pollutants. The gas is emitted during volcanic eruptions and is also produced in many industrial processes. Since coal and petroleum typically contain elemental sulfur, sulfur dioxide is formed when burned. When sulfur dioxide dissolves in water, sulfurous acid is formed. If sulfurous acid is further oxidized in the presence of PM2.5, sulfuric acid (the main component of acid rain) will be produced rapidly and efficiently. This is one reason for concern about the environmental effects of using these fuels as energy sources. [0003] In the atmosphere, sulfur dioxide will be oxidized to form sulfuric acid mist or sulfate aerosol, which is an important precursor of e...
