Batch sorption and column breakthrough studies were conducted to investigate the potential of layered double hydroxides (LDHs) to remove bacteriophage MS2 from contaminated waters. All four of the LDHs evaluated in this study had very high retention capacities for MS2. Sorption results showed that MS2 could be completely removed from 5.2 x 10(2) plaque-forming units (pfu)/mL solution by Mg-Al L...

Emerging contaminants (ECs) are a group of anthropogenic organic pollutants known to have host adverse environmental and health implications. The removal such from aqueous environments ensure water is quality fit for reuse therefore highly important gaining considerable interest. Whilst there multiple approaches used EC remediation matrices, sorption using layered double hydroxides (LDHs) has b...

Layered double hydroxides (LDHs) have been widely investigated in a wide range of applications health, the pharmaceutical industry and material biotechnology industries. This can be considered as group promising materials development new health applications. The combination phosphonic acid with LDHs create hybrid properties.In this work synthesis Zn/Al lay-ered by chemical co-precipitation meth...

Two-dimensional layered double hydroxides (LDHs) have been identified as promising electrocatalysts for the oxygen evolution reaction (OER); however, simple and effective synthesis of high-quality LDHs remains extremely challenging active sites not clarified. Herein, we report a facile solution-reaction method preparing an ultrathin (thickness < 2 nm) nonprecious CoFe-based LDH. Co1Fe0.2 LDH de...

Layered double hydroxides (LDHs) are among the most active and studied catalysts for oxygen evolution reaction (OER) in alkaline electrolytes. However, previous studies have generally either focused on a small number of LDHs, applied synthetic routes with limited structural control, or used non-intrinsic activity metrics, thus hampering construction consistent structure–activity-relations. Here...

The use of layered double hydroxides (LDHs) is a new direction in chemistry cement. influence calcium/aluminum (Ca-Al LDHs) and polycarboxylate ethers (PCE) on the strength development Portland limestone cement has been investigated. It shown that Ca-Al LDHs form slurry with introduction alkaline aluminate accelerator Na[Al(OH)4]. was determined this contributes to significant increase early st...

Since ancient Egypt cosmetics have been a part of our life. Cosmetic products appeal to large variety areas ranging from perfume, hair dyes and care products, toothpastes, dermal face-eye make-up materials. contain biological active components. These compounds generally are sensitive parameters such as light, pH, temperature air oxidation they not stable. This also causes unwanted possibilities...

Lithium–aluminum layered double hydroxides (LDHs) selectively sorb lithium from brines, concentrating and purifying this critical element for subsequent conversion to active battery components. Lithium ion partitioning into lattice vacancies within the LDH structure is enhanced with iron doping. However, process leads a highly coupled set of intercalation interactions whose mechanisms are chall...

Hypersensitive detection of organic pollutions with high toxicity in drinking water always keeps its challenge electroanalysis due to their low concentration and electrochemical redox inert. In this work, a novel nanomaterial modified electrode for the sensitive nitrobenzene (NB) is presented, based on environmental friendly cost-effective Ni/Fe layered double hydroxides functionalized sodium d...
