1755年英國(guó)化學(xué)家布拉克（Black,J.1728-1799）發(fā)現(xiàn)碳酸氣之后不久，發(fā)現(xiàn)木炭1. 在玻璃罩內(nèi)燃燒后所生成的碳酸氣，即使用苛性鉀溶液吸收后仍然有較大量的空氣剩下來(lái)。后來(lái)他的學(xué)生D·盧瑟福繼續(xù)用動(dòng)物做實(shí)驗(yàn)，把老鼠放進(jìn)封閉的玻璃罩里直至其死后，發(fā)現(xiàn)玻璃罩中空氣體積減少1/10；若將剩余的氣體再用苛性鉀溶液吸收，則會(huì)繼續(xù)減少1/11的體積。D·盧瑟福發(fā)現(xiàn)老鼠不能生存的空氣里燃燒蠟燭，仍然可以見(jiàn)到微弱的燭光。待蠟燭熄滅后，往其中放入少量的磷，磷仍能燃燒一會(huì)，對(duì)除掉空氣中的助燃?xì)鈦?lái)說(shuō)，效果是好的。把磷燃燒后剩余的氣體進(jìn)行研究，D·盧瑟福發(fā)現(xiàn)這氣體不能維持生命，具有滅火性質(zhì)，也不溶于苛性鉀溶液，因此命名為“濁氣”或“毒氣”。</p></p><br
