The adsorption experiment of ethylendiamine (en) on porous glass showed selective adsorption of divalent en ion, yielded on apparent adsorption equilibrium constant of 1.00 × 10-8 kg· m-3 and on effective amount of acid acting on en ion on porous glass of 0.506 mol· kg-1 at 298 K. The adsorption experiment of en· nickel complex ion on porous glass yielded an apparent adsorption equilibrium constant of 1.77 × 10-13 kg· mol· m-6 and an effective amount of acid acting on nickel complex ion on porous glass of 1.14 mol· kg-1. For adsorption of en ion, the experimental amount in the en-nickel system agreed with amount estimated by the equation obtained in the en system, and there was no appreciable interaction between the two components adsorbed.
