富氢水制备及保存方法的初步研究

Study of the preparation and the preservation method of the hydrogen-rich water

目的:建立富氢水的制备装置,制备富氢水,并对富氢水的保存方法进行初步研究。方法:采用增加压强的方法制备富氢水,研究不同通气压强(0.1、0.2、0.3、0.4 MPa)、不同通气时间(0.5、1、2、4、8 h)和不同抽真空时间(0、5、10、30、60min)对富氢水中氢气浓度的影响,同时观察温度、储存容器、放置时间、装量和滤膜抽滤对富氢水中氢气浓度变化的影响。结果:通气压强对氢气浓度无明显影响(P>0.05);通气时间和抽真空时间对氢气浓度有一定影响,维持通气4 h以上组较通气4 h以下组以及抽真空5 min以上组较未抽真空组氢气浓度均显著增加(P<0.05或P<0.01);氢气浓度会随着放置时间的延长而逐渐降低(P<0.05);氢气浓度变化与储存容器和保存温度无明显相关关系(P>0.05);氢气浓度变化与容器中富氢水是否装满有明显关系(P<0.05);滤膜抽滤会降低氢气浓度(P<0.05)。结论:在本研究条件下成功制备出一定浓度的富氢水,并对其保存方法有了初步了解。

OBJECTIVE： Preliminary studies were performed on a device for preparing hydrogen-rich water,preparation of hydrogen-rich water,and hydrogen-rich water preservation method. METHODS：After preparation of hydrogen-rich water,the effect of the ventilation under different pressures （0.1,0.2,0.3,0.4 MPa）,the different ventilation time （0.5,1,2,4,8 h） and the different vacuum time （0,5,10,30,60 min） on the hydrogen concentration of hydrogen-rich water were measured,and the impact of the temperature,storage containers,observing time,content and membrane filtration on the hydrogen concentration changes of hydrogen-rich water were also evaluated. RESULTS：The ventilation pressure had no significant effect on the hydrogen concentration（P〈0.05）. Ventilation time and vacuum time showed a certain effect on hydrogen concentration when ventilating above 4 h or vacuum pumping more than 5 min,the hydrogen concentration increased significantly（P〈0.05 or P＆lt;0.01）,which was gradually decreased with the extension of storage time（P〈0.05）. The storage container and the temperature of preservation had no obviously effect on hydrogen concentration（P〉0.05）. The amount of water loaded had obvious effect on hydrogen concentration（P〈0.05）. Filtration reduced hydrogen concentration（P〈0.05）. CONCLUSION：We have successfully prepared hydrogen-rich water in certain concentration,and studied the preservation methods of hydrogen-rich water.
