Sorção de Diuron em minerais da fração argila

Química Nova, 2012
The objective of the present study was to evaluate the adsorption of the herbicide Diuron onto smectite and Fe oxides minerals. Ninety mg of each mineral, 1 mL of 0.15 mol L-1 CaCl2 and 8 mL of Diuron (0.25-10.00 mg L-1) were used in triplicates.

A review of possible mechanisms for mercury migration in diagenesis: Clay to pyrite

Frontiers in Earth Science, 2023
Though sedimentary mercury in marine sediments has been regarded as a geological indicator of volcanic activity based on volcanism activity is the dominant natural source of Hg to the oceans, the influence of diagenesis on mercury cannot be dismissed ...

Clay minerals in the Pliocene–Quaternary sediments of the southern Yangtze coast, China: Sediment sources and palaeoclimate implications

Journal of Palaeogeography, 2014
Clay mineralogy was used as an indicator of the sediment source and prevailing climate and five suites (I–V) were identified throughout the borehole. Smectite was dominant in the bottom suite of the borehole, indicating the sediment was mainly derived ...

Surface hydration‐induced damage in tight oil‐bearing sandy conglomerate reservoirs

Deep Underground Science and Engineering, EarlyView.
A series of techniques such as X‐ray diffraction, scanning electron microscopy, energy‐dispersive spectroscopy, conductivity tests, and infrared thermal imaging were used. The key findings are the identification of a two‐stage surface hydration process and the elucidation of the effects of various minerals and elements on the hydration process ...
