Hydrogen extraction experiment from liquid lithium-lead alloy by gas-liquid contact method has been carried out in own liquid lithium-lead bubbler (LLLB). Experimental results show that, He is more suitable than Ar as carrier gas in the filler tower. The higher temperature the tower is, the greater hydrogen content the tower exports. Influence of carrier gas flow rate on the hydrogen content in the export is jagged, no obvious rule. Although the difference between experimental results and literature data, but it is feasible that hydrogen isotopes extraction experiment from liquid lithium-lead by gas-liquid contact method, and the higher extraction efficiency increases with the growth of the residence time of the alloy in tower.%在自行设计与建造的液态锂铅合金鼓泡器实验系统上,开展了气-液接触法提取液态锂铅合金中的氢.实验结果表明,氦气比氩气更适合作填料塔的载带气；塔温越高,塔出口端氢含量越大；载气流速对出口端氢含量的影响呈锯齿状,无明显规律.实验结果虽然与文献数据有差别,但可以认为采用气-液接触法提取液态锂铅中的氢同位素是可行的,提取效率是随液态锂铅在填料塔中滞留的时间增长而增大的.
