Performance evaluation of polymer-marine biomass based bionanocomposite for the adsorptive removal of malachite green from synthetic wastewater

Preparation and Characterization of a Novel Activated Carbon@Polyindole Composite for the Effective Removal of Ionic Dye from Water

“…When the pH is less than pH PZC , the surface of adsorbent is expected to be negatively charged and it allows adsorption of positive ions. At pH greater than pH PZC , the adsorption of anions is more favorable due to increased positive ions at the adsorbent surface [ 8 ]. As shown in Figure 6 , the pH PZC for AC@PIN composite is 8.0.…”

“…Mudassir et al [ 7 ] reported that PANI@AC could be a potential adsorbent for Methyl Orange removal. Sarojini and co-worker [ 8 ] evaluated the performance of PPy-marine biomass biocomposite for the elimination of Malachite Green from wastewater. Moreover, Saima and co-researchers [ 9 ] prepared different polymeric biocomposites based on PANI, PPy, starch, chitosan, and sugarcane bagasse and successfully employed as adsorbents for the Acid Black-234 under various condition.…”

Facile synthesis of CeO2 nanoparticles for enhanced removal of malachite green dye from an aqueous environment

“…Although many technologies have been developed such as biodegradation, chemical oxidation, electro-coagulation, membrane separation, precipitation, electrodialysis, and adsorption, the cost of operation, effectiveness and environmental impact of each of these strategies are different. [11][12][13][14][15][16][17] Among these techniques, adsorption is more suitable due to its ease of operation, simplicity of design, effectiveness, high efficiency, and availability of a diverse range of adsorbents. 14,[18][19][20][21][22][23] Accordingly, different adsorbents such as biomass, 16,17 activated carbon (AC), [24][25][26] clay composites, 27 and metal oxides and their composites [28][29][30][31][32][33] have been tested to remove malachite green dyes from water.…”

Response Surface Modeling for Malachite Green Removal Using the Box-Behnken Experimental Design

“…In addition, it is considered as a biological staining agent to stain cell tissues to facilitate microscopic observation [6] and as a fungicide in aquaculture to treat parasites, fungal infections, and bacterial infections in fish and fish eggs [7,8]. Despite its extensive use, MG is a highly controversial compound due to its toxic properties known to cause carcinogenesis, mutagenesis, teratogenesis and respiratory toxicity [9].…”

“…A search of the word "malachite green" in the science direct database reflects an increase of over 50% in research on this dye since 2018 (Figure 1). Among the most widely used techniques for the removal of this dye are adsorption, photocatalytic degradation, biodegradation, chemical oxidation, electrocoagulation, membrane separation, and coagulation-flocculation [9][10][11][12]. The latter is widely used due to its simplicity and cost effectiveness.…”
