Trimethylsilylation of commonly occurring primary and secondary minerals in soils

摘要: Summary Soil is formed through the weathering of minerals—mainly silicates—and manner in which these materials weather related to some extent arrangement silica units within their structures. This has been termed degree polymerizafion and can be quantitatively assessed by preparing organic (trimethylsilyl) derivatives separated identified. procedure applied a number primary secondary (including clay highly disordered) minerals occurring soils indicated that: (a) minerals, ferro-magnesian are most susceptible acid attack; (b) inorganic gels, particularly those high alumina, reactive; (c) crystalline especially kaolinite illite, relatively stable.
