Regeneration and Single Stage Batch Adsorber Design for Efficient Basic Blue-41 Dye Removal by Porous Clay Heterostructures Prepared from Al13 Montmorillonite and Pillared Derivatives.

Porous clay heterostructures are a hybrid precursor between the pillaring process and organoclays. In this study, the organoclay was substituted by an aluminium intercalated species clay or pillared alumina clays. A porous clay heterostructure was successfully achieved from an aluminium intercalated species clay, due to the easy exchange of the aluminium species by the cosurfactant and silica species.

organo acid-activated clays for water treatment as removal agent of Eosin-Y: Properties, regeneration, and single batch design absorber.

Organoclays have been proposed as efficient removal agents for colored wastewater treatment. In this study, organo-acid-activated clays were investigated for their ability to remove eosin Y dye molecules. Firstly, the clay was acid activated using sulfuric solution at 90 °C for overnight.

A review of pre- and post-surface-modified neem (Azadirachta indica) biomass adsorbent: Surface functionalization mechanism and application.

In contemporary wastewater treatment industry, advanced oxidation techniques, membrane filtration, ion exchange, and reverse osmosis are used to treat chemically loaded wastewater. All these methods required highly toxic oxidizing chemicals, high capital investment in membrane/filter materials, and the installation of sophisticated equipment. Wastewater treatment through an adsorption process using biomass-based adsorbent is economical, user-friendly, and sustainable.

Surface Functionalization of Bioactive Hybrid Adsorbents for Enhanced Adsorption of Organic Dyes.

In this study, a valuable adsorbent was functionalized using commercial ZnO and a mango seed extract (MS-Ext) as a green approach for synthesis. Fourier-transform infrared spectroscopy, transmission electron microscopy, scanning electron microscopy, and energy-dispersive X-ray analysis spectraconfirmed the presence of bioactive phenolic compounds and Cu2+ ions on the surface of ZnO. Functionalized Cu-doped ZnO/MS-Ext exhibits high efficacy in acidic, neutral, and alkaline medium, as indicated by 98.

Zinc Oxide/Phosphorus-Doped Carbon Nitride Composite as Potential Scaffold for Electrochemical Detection of Nitrofurantoin.

Herein, we present an electrocatalyst constructed by zinc oxide hexagonal prisms/phosphorus-doped carbon nitride wrinkles (ZnO HPs/P-CN) prepared via a facile sonochemical method towards the detection of nitrofurantoin (NF). The ZnO HPs/P-CN-sensing platform showed amplified response and low-peak potential compared with other electrodes. The exceptional electrochemical performance could be credited to ideal architecture, rapid electron/charge transfer, good conductivity, and abundant active sites in the ZnO HPs/P-CN composite.

Hydrothermally Assisted Synthesis of Porous Polyaniline@Carbon Nanotubes-Manganese Dioxide Ternary Composite for Potential Application in Supercapattery.

In this study, ternary composites of polyaniline (PANI) with manganese dioxide (MnO) nanorods and carbon nanotubes (CNTs) were prepared by employing a hydrothermal methodology and in-situ oxidative polymerization of aniline. The morphological analysis by scanning electron microscopy showed that the MnO possessed nanorod like structures in its pristine form, while in the ternary PANI@CNT/MnO composite, coating of PANI over CNT/MnO, rods/tubes were evidently seen. The structural analysis by X-ray diffraction and X-ray photoelectron spectroscopy showed peaks corresponding to MnO, PANI and CNT, which suggested efficacy of the synthesis methodology.

[μ-Bis(diphenyl-arsanyl)methane-1:2κAs:As']nona-carbonyl-1κC,2κC,3κC-(triisoprop-yl phos-phite-3κP)-triangulo-triruthenium(0).

The asymmetric unit of the title triangulo-triruthenium compound, Ru(3)(CO)(9)(μ-Ph(2)AsCH(2)AsPh(2))(P[OCH(CH(3))(2)](3)) or [Ru(3)(C(25)H(22)As(2))(C(9)H(21)O(3)P)(CO)(9)], contains two mol-ecules of the triangulo-triruthenium complex. The bis-(diphenyl-arsanyl)methane ligand bridges an Ru-Ru bond and the monodentate phosphite ligand binds to the third Ru atom. Both the arsine and phosphite ligands are equatorial with respect to the Ru(3) triangle.

Undeca-carbonyl-1κC,2κC,3κC-(triethyl phosphite-1κP)-triangulo-triruthenium(0).

In the title triangulo-triruthenium compound, [Ru(3)(C(6)H(15)O(3)P)(CO)(11)], each Ru atom has distorted octa-hedral coord-ination geometry. The monodentate phosphine ligand is equatorially coordinated to one Ru atom, leaving one equatorial and two axial carbonyl substituents on the Ru atom. Each of the remaining two Ru atoms carries two equatorial and two axial carbonyl groups.
