The pore size, shape and orientation of an illite-dominant clay were mapped during one-dimensional compression, using mercury intrusion porosimetry (MIP), scanning electron microscopy gas adsorption. total porosity was found to spread over the three International Union Pure Applied Chemistry classes pores sizes: micropores (below 2 nm), mesopores (2–50 nm) macropores (above 50 all observed comp...

to this solution, the edge-situated interlattice sites become occupied by ions other than K, presumably leading Nickel sorption in illite suspensions was studied as a function of to partial opening of the interlattice space (Bolt et al., pH (4.5–8.0), reaction time (3 h, 24 h, and 1 wk) and ionic strength (I 5 0.1 and 0.003 M ) using x-ray absorption spectroscopy (XAS) to 1979). characterize th...

Five illitic clays were treated with various inorganic cations and heated to over 1400~ in a high-temperature X-ray diffraction furnace. The illite lattice undergoes dehydroxylation from 475-600~ and the resulting anhydrides begin to disappear at 850~ The major high-temperature phases formed from untreated illites are/?-quartz (1000-1300~ spinel (1000-1400~ and mullite (1150-1400 + ~ Minor amou...

all of the tea plantations in iran are concentrated in the caspian sea region on soils previously developed under deciduous natural forests. this research conducted to study the effect of land use change (from forest to tea) on selected physico-chemical and mineralogical properties of soils under humid climate and mountainous landscape in northern iran. three transects facing west to northwest ...
