Two kinds of harmful gas (such as malodorous gas) adsorbent containing gas adsorption resins were developed. One is a polystyrene polyamine metal (Co) chelating resin capable of adsorbing more than 90% of sulfur-containing (C_2H_5SH and H_2S etc.) or acidic gases (SO_x, NO_x and HCl etc.) within 60 minutes. The other is a polystyrene polysulfonic acid resin that can adsorb more than 90% of basic gases such as NH_3 within 60 minutes. Thus, both resins have large gas adsorption capacity and their stability is good. The harmful gas adsorbents obtained by mixing both resins with active charcoal can adsorb a wide range of harmful gases. Both resins are very economical since they can be regenerated. The practical application of these resins are as follows. (1) Both can be used to remove specific harmful gases. (2) The harmful gas adsorbent is placed in a gas circulating device. (3) The gas adsorption sheet comprising of many corrugated layers of gas adsorbent can be hung from a wall. It should thus be possible to use these resins in many places such as lavatories, childcare rooms, hospitals, building and cars, factories and tunnels and be used to prevent corrosion of precision instruments.
