A Sm-MOF/GO nanocomposite membrane for efficient organic dye removal from wastewater

Abstract

A nanocomposite membrane composed of samarium metal-organic frameworks and graphene oxide nanosheets was fabricated for organic dye removal.

Fabrication of UiO-66/MIL-101(Fe) binary MOF/carboxylated-GO composite for adsorptive removal of methylene blue dye from aqueous solutions

“…A known dose of UiO-66/ MIL-101(Fe)-GOCOOH composite (0.001-0.03 g) was added to MB dye (50 to 300 mg L À1 ). pH optimization (3)(4)(5)(6)(7)(8)(9)(10)(11) was adjusted using 0.01 M of NaOH and/or 0.01 M of HCl. The adsorption process was conducted at various temperatures (25-55 C) under constant agitation rate (250 rpm).…”

“…For instance, methylene blue (MB) dye is mostly utilized for coloring cotton, wood and silk, but its discharge into water bodies even in low concentration leads to various harmful impacts such as eye burning, vomiting, cyanosis, convulsions, tachycardia and methemoglobinemia. 3,5 Accordingly, several techniques have been applied for dye removal such as advanced oxidation, 6 membrane separation, 7 electrolysis, 8 catalytic reduction, 9,10 photocatalytic degradation, 11 occulation. 12 Other than the mentioned techniques, visible light-driven photocatalysis and adsorption methods are considered the most promising technologies in the environmental remediation eld owing to their high efficiencies, low cost, minimal harmful by-products and their low energy consumption.…”

Dye contaminated wastewater treatment through metal–organic framework (MOF) based materials

“…The Sm-MOF/GO membrane had high water permeance (26 L m À2 bar À1 h À1 ) and a high adsorption capacity for RhB (491%) (Table 2). 191 It has been found that these MOF-based membrane investigations are limited to a few MOFs which have been applied for removal of a few dye molecules (MB, CR, MO, RhB, MG, etc. ), and only laboratory-scale short-term tests have been performed.…”

Nanotechnology in the Restoration of Polluted Soil

“…The utilization of NPs based on a metal–organic framework (MOF) has received a lot of important attention lately, but it is primarily employed for drinking water and wastewater treatment [ 16 , 17 , 18 ]. Thus, there is a massive opportunity for scientists to envisage potential uses of MOF in soil remediation.…”
