Transport behavior of nanoplastics in activated carbon column

Environmental Science and Pollution Research, 2022
Nanoplastics can be produced directly from some artificial products, such as cosmetics, or indirectly from the breakup of large pieces of plastic waste. They have a small particle size, large specific surface area, and stable structure and can concentrate toxic compounds in water.

Thermally activated charge transport in carbon atom chains

Nanoscale, 2020
The conductance of alkanedithiol molecular junctions increases under elevated temperatures due to the contributions of superexchange with inter-chain charge hopping.

Carbon dioxide transport through enzymatically active synthetic membranes

Chemical Engineering Science, 1975
The facilitated transport of CO2 through thin liquid membranes, Millipore filter membranes, and cross-linked protein membranes has been investigated using a tracer 14CO2 technique. Both the uncatalyzed reactions and the enzymatic reactions catalyzed by carbonic anhydrase in homogeneous solution and immobilized in several membrane configurations were ...

Charge carrier transport control in activated carbon fibers

Carbon, 2013
Abstract We present the results of measurements of electronic transport in an activated carbon fiber performed over a wide temperature range. The fiber had been subjected to the adsorption of various molecules, one type at a time. The presence of guest molecules inside the fiber’s pores causes significant changes in the electronic transport which has

Human activities changed organic carbon transport in Chinese rivers during 2004-2018

Water Research, 2022
Rivers serve as regulators of global climate by releasing greenhouse gases, burying particulate carbon, and connecting different ecosystem carbon pools. However, long-term organic carbon (OC) transport features across different Asian rivers are not well known due to unavailable data.

Transport and Sorption of Organic Gases in Activated Carbon

Journal of Environmental Engineering, 1996
The relationships among adsorption-desorption kinetics, equilibrium partitioning, and fixed-column breakthrough curves are elucidated for airborne benzene and vinyl chloride on activated carbon grains and fibers. An electrobalance is used to measure adsorption/desorption kinetics and to obtain equilibrium partitioning data; column experiments are ...

Transport and sorption of water vapour in activated carbons

Carbon, 2001
Abstract The adsorption of water vapour on microporous carbons derived from the carbonization of coconut shell has been studied. The adsorption and desorption characteristics of water vapour on the activated carbons were investigated over the pressure range p/p0 0–0.95 in a static water vapour system.
