thermodynamic factor
1.The adsorption process of zinc with amino methylene phosphonic acid resin is investigated And the influences of medium pH, temperature, retention time on adsorption process are studied The adsorption capacity of the resin for zinc is 191 2mg/g·R The thermodynamic parameters are respectively: rate factor ?k 298 ?=1 37×10 -5 s -1 ;
2.The structure and property of molten salt NaCl have been investigated by computerized simulation of molecular dynamics method. The thermodynamic properties, the partial RDP, the structure factor, the cumulative coordination number curve and diffusion coefficients have been calculated.
3.Abstract: Based on the molecular thermodynamic theory,the quantitative relationships between the separation factor and the column temperature,carbon number and mobile phase composition for fullerenes in high performance liquid chromatography are established.The corresponding models are testified by the experimental data of C70 and C60～C96 from different sources.The calculated results show good agreement with the experimental data.
4.The relationship between retention indices and boiling points for homologous series, i. e. I = atb + b , has been derived from both the thermodynamic equations and the definition of Kovats retention index. Slope a is only related to functional group factor G and independent on the stationary phase.
5.The results show that DBPMP possesses much higher extractin and separating capability than PMBP. Especially, the separation factor for La-Ce is as high as 2.04×102 and the average separation factor from La to Tb is 3.84 Results of the thermodynamic studies of extraction about Ce, Pm, Tm and Lu are also reported.
