Effect of aggregate structure on VOC gas adsorption onto volcanic ash soil.
The understanding of the gaseous adsorption process and the parameters of volatile organic compounds such as organic solvents or fuels onto soils is very important in the analysis of the transport or fate of these chemicals in soils. Batch adsorption experiments with six different treatments were conducted to determine the adsorption of isohexane, a gaseous aliphatic, onto volcanic ash soil (Ta...
متن کاملEffect of Humic Acid on the Selenite Adsorption onto Hematite
In the present study, we investigated the adsorption of selenite [Se(IV)] onto hematite, which usually exists in soils and rocks, focusing on the effect of humic acid. The selenite adsorption onto hematite varied with the contact time, finally reaching an equilibrium state in 5 hours. The result was in good agreement with the Parabolic diffusion equation (R 2 = 0.97). The adsorption with differ...
متن کاملRelationship Between Soil Exchangeable Sodium Percentage and Soil Sodium Adsorption Ratio in Marvdasht Plain, Iran
Objective: Soil salinity is one of the major worldwide environmental constraints affecting agricultural production in arid and semiarid regions. Lack of proper management of water and soil resources lead to increase soil salinity and reduce soil fertility. On the other hand, it seems simple and cheap method of measuring soil salinity is necessary. The aim of this study was to determine the rela...
