Sorption of TCE to the caliche soil exhibited linear isotherm at the high TCE concentrations (Co=122-1300 mg L(-1)) but Freundlich isotherm at the low concentration range (1-122 mg L(-1)). Sorption strength of the carbonate fraction of the soil was about 100-fold lower than the sorption strength of soil organic matter (SOM) in the caliche soil, indicating weak affinity of TCE for the carbonate ...

The absorbed water from air into cellulose/ionic liquid gel dramatically increases the apparent ionic Seebeck coefficient. reason is hydrovoltaic voltage that depends on kinetics of absorption/desorption at different temperature.

The garden grass (GG) was firstly used to remove copper(II) from water as bioadsorbent. From the results of characterisation, the GG had the merits of high specific surface area, significant adsorption sites and functional groups. Copper-adsorption significantly depends on the initial copper concentrations, contact time, pH, adsorbent doses, particle sizes and temperature. The positive values o...
