Hierarchical porous induced competent removal of low concentration azo dye molecules by generating a leachy crystalline structure H-MIL-53(Fe)

Engineering of Calcium Alginate- PANI@Sawdust Wood hydrogel Bio-beads for the Removal of the Sulfonate Groups-Containing Orange G dye from Aqueous Solution

“…The equilibrium adsorption isotherm is indispensable to gure out the distribution of OG dye molecules at the Alg-PANI@SD surface, when the adsorption gets to the equilibrium (Feng et al 2020). Therefore, the analysis by Langmuir and Freundlich isothermal models was carried out (Salam et al 2017), their nonlinear equations and equilibrium data were displayed in Table 2, and their tting curves are plotting in Fig.…”

Biochar/α‐Fe2O3/γ‐Fe2O3 Heterjunction Composite for Photocatalytic Removal of Amino Black

“…The removal of azo dye from wastewater is a long‐term task, which has attracted widespread attention from chemists [3–6] . Several approaches have aimed to remove toxic azo dye in wastewater, including absorption, [7,8] biodegradation, [9–12] and chemical degradation [13–14] . Beyond that, the photodegradation method using metal oxides is useful for degrading organic dye into environmentally friendly products, [15] including TiO 2 , [16] ZnO, [17] CdS, [18] SnO, [19] Fe 2 O 3 [20] etc.…”

“…[3][4][5][6] Several approaches have aimed to remove toxic azo dye in wastewater, including absorption, [7,8] biodegradation, [9][10][11][12] and chemical degradation. [13][14] Beyond that, the photodegradation method using metal oxides is useful for degrading organic dye into environmentally friendly products, [15] including TiO 2 , [16] ZnO, [17] CdS, [18] SnO, [19] Fe 2 O 3 [20] etc. The hydroxyl radical (OH * ) is induced by the metal oxides, and reacts to organic dye molecules to degrade them into nontoxic products, which has become one of the popular water treatment method.…”

Cytotoxic and Genotoxic Effects of Some Azo Dyes in Allium cepa Root Tip Cells

“…It is also resistant to oxidizing compounds and light. For example, Orange G (OG) is one of the azo dyes commonly used in paper industry ( Figure 1) [12]. Also, Mordant Black 17 is one of the aromatic dyes compounds and is widely preferred in the textile industry.…”
