Retardation of Nitrogen Leaching by the NO3– Adsorption in the Subsoil in a Watershed of Old Japanese Cedar and Cypress Stands
anion adsorption column experiment forest cutting subsoils volcanic ash soils
<
2009/8/25
Volcanic ash soils contain appreciable quantities of anion adsorption capacity (AEC) due to the variable charge, and they adsorb anions by non-specific adsorption. To study the effect of this characte...
ADSORPTION OF PHENOL FROM AQUEOUS MEDIA BY AN AGRO-WASTE (HEMIDESMUS INDICUS) BASED ACTIVATED CARBON
Phenol agro-waste adsorption Isotherms adsorption kinetics
<
2010/3/26
The adsorption of phenol by an agro-waste based activated carbon prepared from the root
residue of Hemidesmus Indicus (HIC) was investigated to assess its possible use as adsorbent. The effect of var...
Characteristics of the Adsorption of Dissolved Organic Matter by Charcoals Carbonized at Different Temperatures
