This paper highlights the synthesis of a one-dimensional (1D) hierarchical material mesosilica/palygorskite (Pal) composite and evaluates its adsorption performance for anionic dye methyl orange (MO) in comparison with Pal and Mobile crystalline material-41 (MCM-41). The Mesosilica/Pal composite is consisted of mesosilica coated Pal nanorods and prepared through a dual template approach using c...

photocatalytic decolorization of methyl orange (mo) solution has been studied using phosphotungstic acid (hpa) as photocatalyst. the decolorization reaction of mo solution is photocatalysis. the paper reveals that the optimal loading of photocatalyst for decolorization of mo solution (10 mg/l) is 0.6 g/l. the results show that the photocatalytic decolorization reaction of mo with hpa in a homog...

An analysis of the optoelectronic properties and photocurrent generation mechanisms in 2D multilayer crystallites black phosphorus (BP) is conducted from 350 K down to cryogenic temperatures T ≈6 using a broad‐band white light source, results are compared another semiconducting van der Waals solid, MoS 2 . Both BP devices contacted with Mo at bottom as electrode metal. The Mo–BP interface yield...

Magnetic molecularly imprinted polymers (MIPs) capable of selectively recognizing and absorbing 4,4 ′ -methylenedianiline (MDA) were successfully synthesized, using Fe3O4 coated with mesoporous silicon (Fe3O4@mSiO2) as the magnetic carrier, 4-vinyl pyridine (4-VP) functional monomer, ethylene glycol dimethacrylate (EGDMA...

One of the most important directions for environmental remediation is effective removal dyes and toxic heavy metals from water using newly fabricated nanoadsorbents. Here, magnetic Fe3O4 nanoparticles were combined with nitrogen-containing functional group polymers chitosan (CS) polypyrrole (ppy) to synthesize a nanocomposite (polypyrrole@magnetic chitosan) useful removing methyl orange (MO) he...

This study investigates the adsorption behavior of methyl orange (MO) by magnetic activated carbons (MACs) with different ratios AC: Magnetite from aqueous solution. Batch experiments for MO were carried out evaluating thermodynamics and kinetics parameters onto MAC adsorbents. Variables such as pH, initial concentration dye, contact time, temperature have been analyzed. The physicochemical cha...

Abstract The effective removal of organic dyes from aqueous solutions is essential for environmental protection and remediation. Hence, methods fabricating efficient sustainable adsorbents removing toxic are urgently desired. Here, new cellulose/silica microspheres containing amino groups were prepared applied as functional materials capturing anionic pollutants. Tosyl cellulose, which has a hi...

The voltammetric characteristics of Mo (VI) oxinate at the mercury electrode, in the presence of tri-butylammonium perchlorate (tri-BAP) and piperidinium perchlorate (PP) + piperidine (P) as  two different types supporting electrolytes, have been studied in chloroform. With the both supporting electrolytes a two electron irreversible process for the reduction  of Mo (VI) oxinate was observe...
