关于过氧化氢的释氧量,“静脉注射1毫升0.3%过氧化氢溶液可释放10毫升氧”[广西赤脚医生(3)∶30,1978]的提法,我认为是不正确的。0.3%双氧水每1毫升只能释出氧1毫升,换言之,3%过氧化氢溶液每1毫升才能释出氧10毫升。3%过氧化氢溶液的比重约为1.01,故每毫升3%过氧化氢溶液中所含过氧化氢的克分子数为((1毫升×1.01克/毫升×3%)/34克) Regarding the oxygen release amount of hydrogen peroxide, “Ivml injection of 1 ml of 0.3% hydrogen peroxide solution can release 10 ml of oxygen” [Guangxi Barefoot Doctors (3): 30, 1978] is not correct. 0.3% hydrogen peroxide can only release 1 ml of oxygen per 1 ml. In other words, 10 ml of oxygen can be released per 1 ml of 3% hydrogen peroxide solution. The specific gravity of the 3% hydrogen peroxide solution is about 1.01, so the number of moles of hydrogen peroxide contained in the 3% hydrogen peroxide solution per ml is ((1 ml × 1.01 g / ml × 3%) / 34 g)
