Laboratory experiments and model estimates were carried out to evaluate the effectiveness of sorbent for construction Permeable Reactive Barrier (PRB) at downstream H4 tank area in Fukushima-Daiichi Nuclear Power Station September 2014. Measurement cation exchange capacity X-ray diffraction analyses crystal structures natural zeolites. The Sr adsorption isotherms measured these zeolites contact...

Heavy metal pollution in soil has seriously affected the living environment of human beings Among all heavy pollution, cadmium (Cd) is one most difficult to migrate pollutants soil. Therefore, this systematic review includes remediation techniques Cd-contaminated groundwater that using. Different techniques, including pump and treat, permeable reactive barrier, adsorption, biosorption, electroc...

The adaptive variation of the gradient intensity with the diffusion time at a constant optimal b-value is proposed to enhance the contribution of the nuclei diffusing across permeable barriers, to the pulsed-gradient spin-echo (PGSE) signal. An exact simple formula the PGSE signal is derived under the narrow pulse approximation in the case of one-dimensional diffusion across a single permeable ...
