The isotherms of toluene,butanol,ethyl acetate on monolith activated carbon(MAC)were measured with micro-balance at 20℃,60℃,90℃ and 140℃,respectively. The Langmuir,Freundlich,Langmuir-Freundlich,DR and Toth adsorption equations were used to simulate the isothems.

The results indicate that a derived Wilkins equationcan be applied to the adsorption system of benzene-HZSM-5 under the experimental conditions studied. The experimental isotherms coincide well with theoretical ones obtained from above Wilkins equation.

In the calculation for solid hydrogen, the spherical potential approximation suggested by Cui et al. and the effective helium atomic model of ours were adopted. Comparisons of the theoretical results with the avialable experimental data, which are all below 100GPa, were made and it was found that they are in good agreement with each other

The result showed that the adsorption capacity and removal rate of modified attapulgite could rise more than two-fold, and pH value almost has no effect on adsorption and the capacity of adsorption was increased with increment of temperature, and experimental isotherms could be described successfully by improved BET equation.

From the experimental isotherm of adsorption on a zeolite, on the assumption of a quasiindependence of the molecules found in different cavities, it is possible to determine the distribution of the adsorbed molecules along the zeolite cavities.

A method for determination of the adsorption volume from the experimental isotherm of excessive adsorption of gases and the total content equation was proposed.

Adsorption isotherms of benzene on the zeolite HZSM-5 at high temperatures were determined by gravimetric method and treated with the equation of Wilkins.

The Langmuir equation and one of its modified version, Virial equation and the Dubinin Astakhov equation were fitted to high pressure adsorption isotherms of hydrogen. The isotherms covered the experimental range of 77￣298K and 0￣7 MPa. Standard deviation of a model from the measured values was used as the criteria to compare the fitness of different models. the D A equation and the modified Langmuir equation fit the experimental isotherms very well in the whole range tested. However, the Langmuir equation and...

The Langmuir equation and one of its modified version, Virial equation and the Dubinin Astakhov equation were fitted to high pressure adsorption isotherms of hydrogen. The isotherms covered the experimental range of 77￣298K and 0￣7 MPa. Standard deviation of a model from the measured values was used as the criteria to compare the fitness of different models. the D A equation and the modified Langmuir equation fit the experimental isotherms very well in the whole range tested. However, the Langmuir equation and the Virial equation can only be applied above a lower limit temperature. Even for the best fit D A equation, abnormal parameter behavior was observed.
