<p>PURPOSE:To efficiently remove basic gas becoming a harmful gas by bringing gas containing basic gas such as ammonia or trimethylamine into contact with a purifying agent obtained by supporting copper sulfate on activated carbon. CONSTITUTION:Gas (e.g. air, nitrogoen, hydrogen) containing basic gas (e.g. ammonia, trimethylamine) becoming a harmful component is brought into contact with a purifying agent obtained by supporting copper sulfate on activated carbon and adding 1-50wt.% of free moisture to said activated carbon. As a result, the basic gas such as ammonia or trimethylamine contained in gas can be efficiently removed and, especially, a large amount of relatively high conc. harmful gas can be rapidly removed and, therefore, this purifying agent is used, for example, in a detoxifying device in an emergency when harmful gas suddenly leaks from a gas cylinder to obtain excellent effect.</p> |
