In the present paper, determination of isotherms of the exchange reaction between Cu（II） and clays is presented, verifying again the 'cation exchange-surface precipitation' isotherm worked out formerly in our laboratory. A modified BET equation was applied to treating the experimental data and describing the new isotherm. In addition, the mechanism of the effects of organics are further discussed and verified. Based on the isotherm equations and the estimates of the average area occupied by a single molecule on the surface, we put forward a new hypothesis which differs from the current one of 'organic film'.

Kinetics of the Oxidation of Hydrogen Sulfide by Atmospheric Oxygen in an Aqueous Medium

Hydrogen sulfide is an important acid rain precursor and this led us to investigate the kinetics of its oxidation in aqueous phase by atmospheric *** kinetics was followed by measuring the depletion of oxygen in a *** reaction was studied under pseudo order conditions with[H2S]in *** kinetics followed the rate law:-d[O_(2)]/dt=k[S][O_(2)]_(t)(A)Where[S]represents the total concentration of hydrogen sulfide,[O_(2)]_(t)is the concentration of oxygen at time t and k is the second order rate *** equilibria(B-C)govern the dissolution of H_(2)S;the sulfide ion in water forms different species:H_(2)S K1→←HS^(-)+H_(+)(B)HS^(-)K2→←S^(2-)+H^(+)(C)Where K_(1)and K_(2)are first and second dissociation constants of H_(2)***,H_(2)S is present as undissociated H_(2)S,HS^(-)and S^(2-)ions,nature of[H^(+)]dependence of reaction rate required only HS^(-)to be reactive and *** rate law(A)on including[H^(+)]dependence became Equation(D).-d[O_(2)]/dt=k_(1)K_(1)[H^(+)][S][O_(2)]_(t)/([H^(+)]^(2)+K_(1)[H^(+)]+K_(1)K_(2))(D)Our results indicate anthropogenic VOCs such as acetanilide,benzene,ethanol,aniline,toluene,benzamide,o-xylene,m-xylene,p-xylene and anisole to have no significant effect on the reaction rate and any observed small effect is within the uncertainty of the rate measurements.
