不同溶质溶液对氢棒产氢速率的影响
Effect of different solute solutions on hydrogen producing rate of hydrogen rods
摘要
Abstract
Objective To investigate the hydrogen production rate of hydrogen rods in different solute solutions ,and to study the correlations between hydrogen and oxygen concentrations in the solution and the relationships between hydrogen and oxidation-reduction potential .Methods The hydrogen rich solution was produced using metal magnesium to react with water.The experiment was divided into NaCl , Na2SO3, Na2SO4, CH3COOH, and CH3COONa solution groups, respectively, with 0%, 0.2%, 0.9%and 3%in different concentration solutions .The hydrogen content of the corresponding solution was determined at 0, 2, 4, 6, 8, and 10 h.Moreover, the oxygen content in the solution , redox potential and pH value were simultaneously determined .Results Within the same reaction time , the higher concentration of NaCl , the higher the hydrogen production rate .The amount of hydrogen in the solution was negatively correlated with that of oxygen ( R2 =0.9306).The higher the hydrogen content, the lower the oxygen content.With the amount of hydrogen in the solution increasing, oxidation was reduced while pH was increased.The hydrogen-producing rate of hydrogen rods in different solute solutions was the highest with Na2SO3,followed by NaCl and Na2SO4(P<0.05 or P<0.01).In the acetic acid solution, the hydrogen-producing rate of rods was significantly higher than in the sodium salt solution (P<0.05).The hydrogen content increased gradually with time .The oxygen concentration was significantly lower than in the sodium salt solution ( P <0.05), and the oxygen content decreased over time .Conclusion The type and concentration of solutes in solutions and the oxygen content and acidity of a solution have significant influence on the hydrogen -producing rate of hydrogen rods. Therefore, by adjusting the type and concentration of solutes in the solution, we can prepare different types of hydrogen concentration solutions , which can provide detailed reference parameters for hydrogen production of hydrogen rods in clini -cal and practical applications.关键词
