Simultaneous removal of two industrial dyes by adsorption and photocatalysis on a fly-ash–TiO2 composite

The use of titanium (IV) phosphate for metal removal from aqueous and alcoholic samples

“…In the first situation, dyes can be removed from aqueous solution directly via adsorption as well as by simultaneous adsorption and photocatalysis. Duta and Visa have shown the preparation of a fly-ash-TiO 2 composite for the simultaneous removal of two commercial dyes (bemacid red and bemacid blue) via adsorption and photocatalysis [21]. Considering the use of titanium oxide for metal removal, literature has covered a wide range of species.…”

Removal of methylene blue from aqueous solution by electrophoretically deposited titania‐halloysite nanotubes coatings

“…However, these processes do not completely eliminate the dyes and only transfer them from one source to another. Photocatalysis is a technique which has been widely studied for the complete elimination of dyes . Titania (TiO 2 ) in the anatase form is the most widely used and studied material for the photocatalytic degradation of pollutants due to the high photocatalytic activity, high chemical resistance and durability, low cost, nontoxicity, and transparency to visible light .…”

“…Photocatalysis is a technique which has been widely studied for the complete elimination of dyes. [25][26][27][28][29] Titania (TiO 2 ) in the anatase form is the most widely used and studied material for the photocatalytic degradation of pollutants due to the high photocatalytic activity, high chemical resistance and Farrokhi-Rad and Mohammadalipour have contributed equally to this work. durability, low cost, nontoxicity, and transparency to visible light.…”

Basic Dye Adsorption onto Clay/MnFe2O4 Composite: A Mechanistic Study

“…The adsorption using different types of adsorbents is an efficient, cheap and simple method for dye remediation. More recently, the application of composites has gained the attention of the scientific community in view of various advantages (Duta and Visa, 2015;Liu et al, 2016). A composite is a combination of two or more components such as a reinforcing agent and a compatible matrix that offer excellent adsorption properties (Rangabhashiyam and Selvaraju, 2015) and to date clinoptilolites (Çoruh et al, 2010), montimorillonites (Akar et al, 2009), esmectites (Galindo et al, 2013), kaolinites (Wang et al, 2014) and bentonites (Anna et al, 2015) have been successfully employed as adsorption.…”

“…The bentonite in different forms i.e., organotailored, acid and base treated, china clay and wallastonite have been extensively studied as sorbent (Hassani et al, 2015;Oliveira et al, 2003). Moreover, supramolecular gel composites reinforced by using halloysite nanotubes loading with in-situ formed Fe 3 O 4 nanoparticles (Zeng et al, 2016), chemically modified nanoclay (Hassani et al, 2015), polyoxometalate-based metal-organic framework , Co 3 O 4 -ZrO 2 composites (Singh et al, 2015), fly-ash-TiO 2 (Duta and Visa, 2015), activated carbon/c-Fe 2 O 3 (Fayazi et al, 2015), plastic and plant wastes (Lin et al, 2015), mesoporous graphene/Fe 3 O 4 /chitosan (Van Hoa et al, 2016), magnetic nano-adsorbent (Liao et al, 2003), Fe 3þ and Pt 4þ impregnated TiO 2 nanostructures (Pal et al, 2016), chitosan-lignin (Nair et al, 2014), chitin/graphene oxide hybrid (Gonza´lez et al, 2015), NiFe 2 O 4 /Ag 3 PO 4 (Zhao et al, 2016), self-immobilization of a magnetic biosorbent (Zhang et al, 2016), defective UiO-66 and polyaniline/silver composites (Salem et al, 2016) have been reported to be highly efficient adsorbents.…”
