Whereas it is often acceptable to consider net sorption, let us consider briefly the four basic types or mechanisms of sorption: 1. Adsorption is the process wherein the chemical in a solution attaches to a solid surface, which is a common sorption process in clay and organic constituents in...
Sorption of PACs to soils could affect their fate in the environment [74]. Some PACs have higher sorption abilities than others. Their sorption depends on their physicochemical properties and on the characteristics of the sorbent and those of the solution. Tremendous efforts have been made in the...
Pesticides are chemical compounds designed to be used as plant protection products (PPPs). They are applied in the field for the protection of plants against pests, weeds, and several diseases that affect and decrease the quantity and quality of agricult
The reactivity of solutes and their mobility in soils play a significant role in their leaching losses beyond the root zone, availability to uptake by plants and the potential contamination of groundwater. The ability to predict the mobility of dissolved chemicals in the soil is a prerequisite in...
A CRITICAL ASSESSMENT OF SORPTION-DESORPTION MECHANISMS AT THE SOIL MINERAL/WATER INTERFACE Sorption is one of the most important chemical processes in soil. It affects the fate and mobility of nutrients and contaminants in soils and waters greatl... AM Scheidegger,DL Sparks - 《Soil Science》 ...
Thus, current research progress and knowledge gaps regarding adsorption mechanisms of organic chemicals on MNPs are the main focus of this review. In addition, MNP application, general properties, occurrence, and entry pathways to the environment are summarized. MNP colloidal behaviors, which are ...
Naturally occurring organic matter in soils is also important in the adsorption of uranium. Several mechanisms have been proposed for U(VI) adsorption by organic matter (Kaplan and Serne1995). The adsorption of uranium to humic substances may occur through ion exchange and complexation processes that...
The objective of the present work is to investigate the retention of Ni(II) on the CA soil in batch experiments, testing the influences of the contact time, pH and temperature and using EXAFS and XPS to assess the retention mechanisms at the molecular level. Results Sorption investigation. ...
