H-acid adsorbed onto TiO_ 2 surface through one sulphonic group,which occupied less surface area leading to higher adsorption capacity, weaker adsorption bond, and less adsorption irreversibility.

The effect of initial adsorbate concentrations and adsorption kinetic processes on adsorption isotherms and adsorption irreversibility was studied, by introducing a same total amount of Zn (Ⅱ) into 2 different adsorption solutions (δ-MnO_2 and γ-MnOOH) in various batches (1, 3, and 15 batches).

The reversible adsorption heat of methanol on carbon nanotubes and Mo/CNT catalyst is 16.

2 times faster than that of reversible carbon monoxide, Becausethe reversible adsorption hydrogen and irreversible carbon monoxide are responsible fo.

The results show that the adsorbed carbon monoxide and hydrogen on comme-rcial Ni catalyst can be distinguished as reversible and irreversible adsorption under real reactionconditions.

The silicagel column has showed an irreversible adsorption equilibrium for epirubicin and its analogues with slightly acidic or neutral mobile phases in hydrophilic interaction chromatography (HILIC).

The results show that the adsorbed carbon monoxide and hydrogen on comme-rcial Ni catalyst can be distinguished as reversible and irreversible adsorption under real reactionconditions.
