英文摘要 | The kinetic order and activation energy of Cu, Ag, Ni and In for atom formation under isothermal condition in a graphite furnace have been determined by means of a newly developed method. A 2/3 order kinetic release of Cu indicates that the analyte desorbs from the surface of microdroplets on the probe with desorption energy of 193 +/- 24 kJ mol(-1). For Ag and In a fractional order of near 1/2 with E(a) values of 248 +/- 5 kJ mol(-1) and 123 +/- 8 kJ mol(-1), respectively, was obtained which implies the release of free Ag or In atoms from the interface of 2-D islands. As to Ni, a first-order kinetic process was observed with E(a) value of 297 +/- 6 kJ mol(-1), which suggests that the analyte desorbs from tungsten probe surface as highly dispersed atoms. The activation energy may represent the nickel-tungsten interaction energy. |
