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
cedar wood Freundlich isotherm pH dependence rice-straw water
2009/6/10
We investigated the adsorptive volume and rate, adsorption isotherm, and the pH dependence of charcoals obtained from carbonizing cedar (Cryptomeria japonica D. Don) wood chips at various temperatures...
Method for Estimating Competitive Adsorption of Herbicides on Soils
atrazine competitive adsorption estimating method linuron soil
2009/3/5
The effects of mixed herbicides in soils may differ due to interactions. Since adsorption amounts and ratios change nonlinearly with herbicide concentrations, it is necessary to control the total nu...
Aerobic metabolism and adsorption of pyrethroid insecticide imiprothrin in soil
imiprothrin soil metabolism soil adsorption
2009/3/5
Imiprothrin, a unique type of pyrethroid having an imidazolidinyl ring in its alcohol moiety, was rapidly degraded in two aerobic U.S. soils. The half-lives of biologically active trans isomer were ...
