Mechanisms of Slow Sorption of Organic Chemicals to Natural Particles
TL;DR: The use of equilibrium expressions for sorption to natural particles in fate and transport models is often invalid due to slow kinetics and diffusion limitations appear to play a major role.

Sorption phenomena in subsurface systems: Concepts, models and effects on contaminant fate and transport
TL;DR: In this article, current levels of understanding of the reactions and processes comprising sorption phenomena are discussed, as well as the forms and utilities of different models used to describe them, and the translation of these concepts into functional models for characterizing sorption rates and equilibria.

Effects of organic matter heterogeneity on sorption and desorption of organic contaminants by soils and sediments
TL;DR: A recent review as mentioned in this paper highlights the major progress over the last decade on characterization of geochemically heterogeneous soil/sediment organic matter (SOM) and the impacts of SOM heterogeneity on sorption and desorption of hydrophobic organic contaminants (HOCs) under equilibrium and rate limiting conditions.

A Distributed Reactivity Model for Sorption by Soils and Sediments. 4. Intraparticle Heterogeneity and Phase-Distribution Relationships under Nonequilibrium Conditions
Walter J. Weber,Weilin Huang +1 more
TL;DR: In this article, the authors examined the time dependence of solute phase distribution relationships (PDRs) in completely-mixed batch reactors and found that nonequilibrium PDRs changed from approximately linear form to increasingly nonlinear form as the time of reaction increased.
Journal ArticleDOI
Fast and slow rates of naphthalene sorption to biochars produced at different temperatures.
TL;DR: The results illustrate that the sorption rate of a solute with biochars is controlled largely by thesolute's diffusivity in the biochar's partition phase, in which the medium compactness affects directly the solute diffusivities.

Sorption of hydrophobic pollutants on natural sediments
TL;DR: In this article, the authors investigated the sorption of hydrophobic compounds (aromatic hydrocarbons and chlorinated polycyclic aromatic compounds) spanning a concentration range in water solubility from 500 parts per trillion (ppt) to 1800 parts per million (ppm) on local pond and river sediments.
