“…The theoretical treatment accepted here differs from the other often used approaches such as the NICA (nonideal competitive adsorption) model ,,, or application of the multicomponent Langmuir (Markham−Benton) equation ,,, N e = N s K L c e 1 + K L c e + K H 10 − pH in which the monolayer capacity for metal ions is treated as pH-independent and equal to N s . The influence of pH on the equilibrium adsorption isotherm in our treatment is restricted to the regulation of the monolayer capacity Q value as expressed by eq .…”

The effect of pH is studied on the equilibrium and kinetics of heavy metal biosorption. A concept of an effective surface capacity is introduced to describe the equilibrium isotherms of metal ion adsorption. That effective surface capacity is controlled by adsorption of protons. The obtained simple theoretical expressions appear to be very efficient in correlating equilibrium isotherms of adsorption of two kinds of heavy metal ions on two kinds of biosorbents. Next, the statistical rate theory is applied to develop the related expressions for adsorption kinetics. These expressions appear to be very efficient in correlating kinetic isotherms measured at various pH values.

There are few computer models that can simulate winter freeze-thaw conditions and spring snowmelt hydrology for agricultural tile drained lands. DRAINMOD, which is used widely to simulate tile drainage flows, has not been extensively applied during colder periods in eastern Canada. This study analyzes the performance of DRAINMOD for surface runoff and subsurface drainage predictions in southern Quebec during spring snowmelt. The model was tested with five years of field data. DRAINMOD was found to be adequate in predicting spring snowmelt hydrology, except for subsurface drainage at one site. It was found that soil characteristics had a major influence on model performance.Résumé : Il existe peu de modèles informatiques qui simulent le gel/dégel d'hiver et l'hydrologie de la fonte des neiges printanière pour les terres agricoles ayant un réseau de drainage par canalisation souterraine. Le modèle DRAINMOD, largement utilisé pour simuler les écoulements des réseaux de drainage par canalisation souterraine, n'a pas été utilisé de manière extensive durant les périodes froides dans l'Est du Canada. La présente étude analyse le rendement de DRAINMOD à prédire de drainage sous la surface et l'écoulement de surface dans le Sud du Québec durant la fonte des neiges printanière. Le modèle a été validé en utilisant cinq années de données de terrain. DRAINMOD s'est révélé être adéquat pour prédire l'hydrologie de la fonte des neiges printanière, sauf pour le drainage sous la surface à un seul site. Les caractéristiques des sols influencent grandement le rendement du modèle. [Traduit par la Rédaction]
