Slowly breaking acceleration was observed in anion-exchange resinDid not join rupture is cation exchange resinWas in the acidic cation exchange afterConsidered to be urbanites replacement action is weak.
Gradual Aedes was observed in the anion exchange resin cation exchange resin was not torn was acidic cation exchange even after it is believed that anion exchange action is weak
With the anion exchange resin was added at the fracture was observed even after cation exchange resin cation exchange and additive stress fracture was weak acid dianion and exchange effects are considered.
