The 0.1/dL copper sulfate solution may be used to replace distilled water for humidifying oxygen. It can reduce the carrier rate and prolong the using time. There is little copper-ion in the oxygen while the 0.5/dL copper sulfate solution were used continuously for 9 days. The oxygen humidified by copper sulfate solution has no peculiar smell. The solution is cheap, easy to make, and has broad bacteriostatic spectrum.
0.1/dL的硫酸铜溶液可用于替代蒸馏水来湿化氧气。它能降低带菌率并延长使用时间。当连续使用0.5/dL的硫酸铜溶液9天时，氧气中铜离子含量极少。用硫酸铜溶液湿化的氧气无异味。该溶液价格便宜、易于配制且抑菌谱广。
