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.

The effects of soil property,especially the amount of soil organic carbon,on irreversible adsorption of pesticides were observed in the study of irreversible sorption of Azin.

The hysteresis phenomenon was mostly caused by irreversible sorption of PCP on lip.

Irreversible sorption of aldicarb was found In all 4 experiments The total sorption amount ( q total ) included two parts:reversible sorption amount ( q rev ) in the labile compartment and irreversible sorption amount ( q irr ) in the irreversibly sorbed compartment.

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 electrochemical behaviors of irreversibly adsorbed Sad on Pt electrode and the processes of adsorption and oxidation of 1,2-Propanediol on Pt/Sad electrode were studied by cyclic voltammetry and electrochemical quartz crystal microbalance (EQCM).
