Reduced adsorption of caesium on clay minerals caused by various humic substances [PDF]

open access: yes, 1999
The effect of the addition of various humic substances on the adsorption of caesium on two mineral clays has been studied. All measurements were carried out in dilute suspension under controlled conditions of temperature and ionic strength.

Adsorption of Energy in Photocatalytic Reactors [PDF]

open access: yes, 1985
The dissociation of water to hydrogen and oxygen requires energy ∆G298 = 228 kJ/mole. By irradiating a semiconductor with light of energy greater than this amount, one may product electrons in the excited state and electron vacancies at the surface that can perform the photochemical reduction (2H+ + 2e− → 2H → H2) and oxidation (2OH− + 2+ → H2O2→ H2O +
