摘要
设计用于可见光中催化还原CO2产物分析的色谱分离系统。以Ar作载气通过高分子小球色谱柱与分子筛色谱柱组合,分离检测CO2还原产物中H2,O2,CH4,CO,C2H4,C2H6和C2H2的含量,分离过程中还原产物峰型对称,分离度好。样品加标回收率97.4%~101.8%,测定结果精密度不大于1.23%,相对误差为-2.58%~1.81%。该仪器测试结果准确,性能稳定。
A chromatograph was developed to analyze the products of visible light catalytic reduction of CO2.Ar was used as carrier gas to separate and detect the reduction products H2,O2,CH4,Co,C2H4,C2H6 and C2H2 of CO2 through the combination of polymer small sphere column and molecular sieve column.During the separation process,the peak type of reduction products was symmetrical and the resolution was good.The recovery of the sample is 97.4%-101.8%,the precision of the result is not more than 1.23%,and the relative error was-2.58%-1.81%.The test results of the instrument are accurate and the performance is stable.
