“…5 D). Several researchers stated that the behavior and biosorption efficiency is mainly dependent on the surface area as well as porosity of the nano-sorbent particles 10 , 19 , 38 – 40 . It is evident from the elemental analysis that the presence of Fe, O and N peaks in the EDX, indicating the fabrication of Fe 3 O 4 -NPs impregnated chitosan beads (Fig.…”

“…The eradication of textile and industrial wastewater using alternative adsorbents, particularly synthetic and natural polymers, is of great interest 1 , 5 , 19 . Chitosan, a linear positively charged polysaccharides obtained by the deacetylation of chitin, has been used as effective adsorbent for toxic dyes 8 , 20 and heavy metals 1 , 21 due to its promising properties such as ecofriendly, bioactivity, renewability, nontoxic and high amino and hydroxyl contents 1 , 5 , 8 .…”

The release of different hazardous substances into the water bodies during the industrial and textile processing stages is a serious problem in recent decades. This study focuses on the potentiality of Fe3O4-NPs-based polymer in sustainable bioremediation of toxic substances from contaminated water. The biosynthesis of Fe3O4-NPs by A. tamarii was performed for the first time. The effect of different independent variables on the Fe3O4-NPs production were optimized using Plackett–Burman design and central composite design (CCD) of Response Surface Methodology. The optimum Fe3O4-NPs production was determined using incubation period (24 h), temperature (30 °C), pH (12), stirring speed (100 rpm) and stirring time (1 h). The incorporation of Fe3O4-NPs into chitosan beads was successfully performed using sol–gel method. The modified nanocomposite exhibited remarkable removal capability with improved stability and regeneration, compared to control beads. The optimal decolorization was 94.7% at 1.5 g/l after 90 min of treatment process. The reusability of biosorbent beads displayed 75.35% decolorization after the 7th cycle. The results showed a highly significant reduction of physico-chemical parameters (pH, TDS, TSS, COD, EC, and PO4) of contaminated wastewater. The sorption trials marked Fe3O4-NPs-based biopolymer as efficient and sustainable biosorbent for the elimination of hazardous toxic pollutants of wastewater in a high-speed rate.

“…Kumar and coworkers discussed the applications of grafted chitosan in dye removal [ 68 ]. Gautam and coworkers prepared a Fe 3 O 4 loaded chitin nanomaterial (MCH NM) adsorbent and tested the removal of Reactive Blue 13 (RB13) dye from aqueous solution [ 69 ]. Batch adsorption revealed adsorption activity of 199.02 mg/g towards RB13 dye.…”

“…CuO oxide nanowires incorporated chitosan (CS) and polyvinyl alcohol (PVA) polymeric nanocomposite (CS-PVA@CuO) were used for the removal of Acid Blue 25 (AB25) with an adsorption capacity of 171.4 mg/g [ 76 ]. Table 2 summarizes some of the recent dye removal studies carried out using cellulose, chitin and chitosan-derived adsorbents [ 25 , 26 , 58 , 59 , 60 , 61 , 62 , 63 , 64 , 65 , 66 , 67 , 68 , 69 , 70 , 71 , 72 , 73 , 74 , 75 , 76 , 77 , 78 ]. Generally, the adsorption capacity of an adsorbent is governed by the source and the surface properties such as porosity and surface area.…”

“…This process is also known as in situ chemical oxidation. During the oxidation process, those reactive species engage in complete degradation of large and complex organic compounds, including industrial dyes into intermediates and subsequently mineralizing those intermediates into water and simple inorganic compounds and ions such as carbon dioxide (CO 2 ), sulfates (SO 4 2– ), chloride (Cl – ) and nitrates (NO 3– ), without being transferred into another phase [ 68 , 69 ]. The key advantages and disadvantages of AOPs are summarized in Table 4 [ 25 ].…”

Synthetic dyes have become an integral part of many industries such as textiles, tannin and even food and pharmaceuticals. Industrial dye effluents from various dye utilizing industries are considered harmful to the environment and human health due to their intense color, toxicity and carcinogenic nature. To mitigate environmental and public health related issues, different techniques of dye remediation have been widely investigated. However, efficient and cost-effective methods of dye removal have not been fully established yet. This paper highlights and presents a review of recent literature on the utilization of the most widely available biopolymers, specifically, cellulose, chitin and chitosan-based products for dye removal. The focus has been limited to the three most widely explored technologies: adsorption, advanced oxidation processes and membrane filtration. Due to their high efficiency in dye removal coupled with environmental benignity, scalability, low cost and non-toxicity, biopolymer-based dye removal technologies have the potential to become sustainable alternatives for the remediation of industrial dye effluents as well as contaminated water bodies.
