Ginsenoside Rg1 and Re were prepared by chromatography column from Panax ginseng raw material,and the isotherms of ginsenoside Rg1 and Re were determined by frontal analysis(FA) on spherical C18 solid phase.
由于双组分吸附竞争的复杂性,其测定相对于单组分吸附等温线有一定的难度,报道的双组分吸附等温线测定的方法有前沿流速法[1]、微扰法[2-3]、迎头法[4-6]、逆方法[7-8]等。
The adsorption and reaction of thiophene and hydrogen on catalyst Mo-Co/Al_2O_3 were studied by the frontal chromatography technique.
用迎头色谱法研究了噻吩和氢在Mo-Co/Al_2O_3催化剂上的吸附与反应。
The line of isothermal adsorption with polysacharidcs adsorbent at 70℃ , 80℃ and 90℃ respectively is determined by the method of frontal chromatography in this paper.
本文是在研究以多醣类物质作吸附剂制取无水乙醇的新工艺基础上,采用迎头色谱法测定了吸咐等温线,突验数据通过回归分析,获得符合Freundlich型的吸咐等温方程,计算值与实验结果吻合较好。
And the feasibility of the head-on intercepting tactical ballistic missile is also approached in detail.
最后着重探讨了该制导方法迎头拦截弹道导弹的工程可行性。
