Using 13CO2-CO isotope exchange technique, the rate constant of CO2 dissociation on the surface of molten oxide containing iron oxide can be accurately measured, and the kinetic process also can be analyzed and discussed.

The results of isotopic exchange of(()~(18)O),temperature-programmed surface reaction of ethanol(C_2H_5OH-TPSR),temperature-programmed desorption of CO(CO-TPD),and temperature-programmed reduction of H_2(H_2-TPR) show that the Pt phase is amorphous and well dispersed on the support surface.

Recovering deuterium from uranium deuteride bed by means of the isotopic exchange reaction between the solid and gas phases at room temperature is introduced.

This paper presents main specific properties of a few hydrophobic catalysts made by ourselves with which isotope exchange experiments of H-T at atmospheric temperature are made.

For this purpose, we have investigated the isotope exchange process for the trace recovery from the imitative residue of the alloy.

High temperature solid state catalytic isotope exchange reaction provides a new effective method for the preparation of tritium of labelled organic compounds which have high specific activity and bioactivity.

Isotopic technique is a rapid, accurate, sensitive and reliable way to trace the substance exchange process inside a system or between two systems, particular in tracing the origin of substance entering a system, which make it unexampled and widely applied in life science, environmental science and other areas.

The functions of environmental isotope techniques and the main problems occurred in their applications to tunneling are presented.

The D_2 pulse reaction results over Co-CeO_2/SiO_2 and Co/SiO_2 catalysts showed that the addition of CeO_2 increased the catalytic activity of Co/SiO_2 for the H-D isotopic exchange and the reactivity of H from Si-OH for CO hydrogenation.
