Layered double hydroxides (LDHs) are a class of two-dimensional (2D) clay compounds that consist positively charged host layers and exchangeable interlayer anions. The stability their assemblies in aqueous environment is challenge due to the extremely high hydrophilicity, which limits use membrane-based technologies. Here, we propose graphene oxide (GO) armour protection strategy substantially ...

Layered Double Hydroxides (LDH), anionic clays, is a family of compounds which have attracted considerable attention in recent years[1-4] such as catalysis[5], adsorption[6], ion exchange[7], biomedical application[8] and Defluoridation Capacity (DC)[9]. The structure of most of these materials corresponds to that of hydrotalcite[10]. LDHs are characterized by the general formula [M1-xM III x(O...

As the most commonly prescribed tricyclic antidepressant, amitriptyline (AT) is frequently detected in wastewater, surface runoff, and effluents from sewage treatment plants, and could potentially reach agriculture land through the application of municipal biosolids or reclaimed water. Kaolinite is one of the most important soil components under warm and humid climate conditions. In this study,...

The aim of our experiment was to determine the effect of heating oil application on the count of microorganisms and some physico-chemical properties of limed and lime-free soil and soil sown with yellow lupine of the Markiz variety and unsown soil. The results obtained indicate that heating oil deteriorated the physico-chemical properties of the experimental soil (acidification, decrease in the...

The yield response of various crops to salinity under field conditions is affected by soil processes and environmental conditions. The composition of dissolved ions depend on soil chemical processes such as cation or anion exchange, oxidation-reduction reactions, ion adsorption, chemical speciation, complex formation, mineral weathering, solubility, and precipitation. The nature of cations and ...

Tailings produced during bitumen extraction from surface-mined oil sands ores (tar sands) comprise an aqueous suspension of clay particles that remain dispersed for decades in tailings ponds. Slow consolidation of the clays hinders water recovery for reuse and retards volume reduction, thereby increasing the environmental footprint of tailings ponds. We investigated mechanisms of tailings conso...

1. Total body water, extracellular fluid, total exchangeable potassium and total exchangeable sodium were measured by the multiple isotope-dilution technique in eight patients with congestive cardiac failure. Measurements were made on each patient while in failure and then again after treatment and recovery. 2. Compared with five control subjects in whom the same measurements were made, patient...

Abstract The purpose of the study was to evaluate possibility removing heavy metal cations from single-metal spiked soil samples, which were pretreated with nanoscale zero-valent iron (nZVI) particles. Sandy artificially contaminated copper (Cu), cadmium (Cd), nickel (Ni), and lead (Pb). Contaminated samples amended different doses nZVI (0.35, 0.70 1.05 %). A sequential extraction method used d...

As a means of distinguishing between the broad groups of flay minerals, chemical analysis may be a valuable supijlement to other methods, but rarely will it remove the necessity for other methods, X-ray analysis in particular. The twoand three-layer clay minerals may be distinguished by the SiOj • AlzOs ratio or SiOz • sesquioxide ratio, but these ratios do not provide criteria for dividing eit...
