초록
It’s possible for a human to breathe under water, if dissolved oxygen is effectively used. Fish can stay under water usingthe gill which extracts dissolved oxygen from water. Water includes small amounts of oxygen, so a human needs larger amounts ofwater to acquire oxygen enough for underwater breathing. The exhalation gas from a human is another method to get higher amountsof oxygen under water. It mainly composes of oxygen, nitrogen and carbon dioxide. So, if only carbon dioxide is decreased, theexhalation gas has good characteristics for breathing of a human under water. In this paper, composition of the exhalation gas from a human was analyzed using GC. Based on these results, the synthesized gaswas prepared and mixed into water which was used for experimental devices to analyze separation characteristics of dissolved gasesfrom water. Experimental devices included a water pump, a hollow fiber membrane module and a vacuum pump. The effects ofpressure and water flow on separation characteristics of synthesized gas were investigated. The compositions of gases separated fromwater using synthesized gas were investigated using GC. These results expect to be applied to the development of underwaterbreathing technology for a human.
