摘要
建立了一种测定电极电解碱性混合水溶液分离系数的方法.当对氧化氘(D2O)/氧化氢(H2O)混合碱性水溶液进行电解时,电解产生的混合气体中的氕氘比(n1,g(D)/n2,g(H))可通过低温气相色谱法确定,电解后混合碱性水溶液中的氕氘比(n1,l(D)/n2,l(H))可通过红外光谱法确定.根据气相中的氕氘比和液相中的氕氘比(即分离系数计算公式)可以计算得到不同电极材料电解D2O/H2O混合碱性水溶液时的分离系数.该方法简单易行,可应用于评价不同泡沫镍基电极材料电解碱性混合水溶液时对D和H的分离能力,以寻找良好的电催化材料.
A method was established to measure the separation factor of electrode material for electroly-zing alkaline aqueous solution.The （n 1 ,g（D）/n 2 ,g（H））ratio of mixed gases from electrolysis was deter-mined quantitatively with cryogenic gas chromatography （GC）when we electrolyzed alkaline aqueous solu-tion that deuterium oxide and hydrogen oxide contain 30% of the potassium hydroxide.The （n 1 ,l（D）/n 2 , l（H））ratio of alkaline aqueous solution after electrolysis was tested quantitatively with the infrared spec-troscopy,and then,the separation factor of different material was obtained according to the formula of separation factors.This method can be used to evaluate the separation ability of different electrode material for deuterium and hydrogen,which is helpful in the search of excellent electrode materials.
