Publikováno v: Water, Air, and Soil Pollution. 137:95-116
The sequential extraction procedure proposed by the European Commission Measurement and Testing Programme, combined with Scanning Electron Microscopy and Energy Dispersive X-ray Analysis(SEM/EDS), was applied to identify and quantify the chemical and

hk-Ordering in Aluminous Nontronite and Saponite Synthesized Near 90°C: Effects of Synthesis Conditions on Nontronite Composition and Ordering
Autor: Françoise Elsass, V. C. Farmer, W. J. McHardy, M. Robert
Publikováno v: Clays and Clay Minerals. 42:180-186
In studies on the fate of aluminium in the environment, nontronite and saponite have been obtained by synthesis in reducing alkaline conditions close to those prevailing in poorly drained soils developed from limestones. The two minerals obtained hav

The conversion of montmorillonite to interstratified halloysite-smectite by weathering in the Omi acid clay deposit, Japan
Autor: Y. Sawada, W. J. McHardy, J. D. Russell, M. J. Wilson, T. Watanabe
Publikováno v: Clay Minerals. 27:159-173
A B S T R A C T: The weathering of montmorillonite in the acid clay deposit at Itoigawa, Japan has been investigated by X-ray diffraction (XRD), infrared spectroscopy (IR) and scanning electron microscopy (SEM). In the lower, least weathered part of

Chemistry of illite-smectite inferred from TEM measurements of fundamental particles
Autor: Jon Srodon, D. J. Morgan, W. J. McHardy, F. Elsass
Publikováno v: Clay Minerals. 27:137-158
Mixed-layer illite-smectites (I-S) have a stable charge on the illite interlayer equal to 0·89/O10(OH)2, as shown by electron microscope measurements of mean fundamental particle thickness, using both Pt-shadowing and high-resolution techniques. Thi

Chemical and mineralogical forms of Cu and Ni in contaminated soils from the Sudbury mining and smelting region, Canada
Autor: M. J. Wilson, S. Dudka, W. J. McHardy, P. Adamo
Publikováno v: Environmental pollution (Barking, Essex : 1987). 91(1)
Available information on soil contamination by trace elements in the Sudbury Cu/Ni mining and smelting region consists largely of total elemental concentration data. Little is known about the mode of occurrence and behaviour of Cu and Ni (the main me

X-ray fluorescence spectroscopy and microanalysis
Autor: W. J. McHardy, E. E. Lachowski, D. C. Bain
Publikováno v: Clay Mineralogy: Spectroscopic and Chemical Determinative Methods ISBN: 9789401043137
This chapter deals with the X-ray emission that can be generated by bombarding a specimen with high-energy X-radiation, which in turn is generated by bombarding an appropriate anode material with high-energy electrons. The basis for chemical analysis
