Chemical Improvement of Clay Soils in situ Using Electrokinetic Processes
been widely researched as surface and deep soil treatment techniques (Figure 1). For certain practical situations, such as house foundations on expansive soil, mixing is not possible. Current research has shown that chemical treatment using a potential difference to transport chemical ions between bespoke electrodes can overcome such problems, whilst achieving the desired results. However, a ma...
متن کاملEffect of Clay Minerals on Extractability of Heavy Metals and Sewage Sludge Mineralization in Soil
An incubation experiment lasting 111 d was carried out to study the effect of the addition of three clay minerals (Nabentonite, Ca-bentonite, and zeolite) to soil derived from sewage sludge on water-extractable and exchangeable forms of four heavy metals (Zn, Cd, Cu, and Ni), as well as on soil organic matter mineralization, microbial biomass C and the release of inorganic N. The addition of cl...
متن کاملClay Minerals as Natural Nanosheets
Particles with nanometer dimensions (nanoparticles) are all around us. The finest particles of sand are blown by the wind over thousands of kilometers. The finest particles of soils are either eroded by the wind in extremely dry conditions or by water under wet conditions and deposited hundreds of kilometers or more from the origin. The air contains nanoparticles of carbon, ice, and oxides and ...

15 صفحه اولDetecting Clay Minerals in Soils through Hyperspectral Remote Sensing
Images of representative clayey bare fields were chosen from a high spatial resolution hyperspectral dataset that was acquired with the prototypal airborne Hyper SIM-GA sensor from Selex Galileo simultaneously with ground soil spectral signatures and the collection of samples. After both the pre-processing and calibration of the SIM-GA data, the mapping procedure was developed using the 2-2.45 ...
