“…[13] Around 50,000 tons of dyes are released annually into the environment from various dye industries, significantly threatening the aquatic systems and polluting local drinking water. [14] Although, there are several techniques such as membrane separation, [15] combustion, [16] photocatalytic degradation, [17] biochemical treatment, [18] chemical deposition, [19] nano absorbents, [20] activated carbon, [21] nanocomposite, [22] chemical precipitation, [23] ion-exchange, [24] membrane technologies, [4a] advanced oxidation processes, [25] electrochemical techniques, [26] coagulation-flocculation, [27] floatation techniques, [28] etc. reported for water remediation.…”

A single amino acid in a peptide sequence can play an important role to tune the self-assembly and hydrogelation behaviour. Here, a C-terminal cysteine-containing ultrashort peptide hydrogelator forms hydrogel through noncovalent and covalent interactions. Interestingly, the hydrogel is insoluble in water and buffer solutions at different pH values (1-13) and is thixotropic and injectable. In recent years, removing dyes from contaminated water has become a significant concern because of the shortage of freshwater resources. Therefore, the adsorption of dyes through a reliable, straightforward, nontoxic, cheap, and environmentally friendly adsorbent has become a popular topic. Hence, the hydrogelator was exploited to remove organic dyes from wastewater, harnessing its applicability in the gel phase and solid supports (filter paper and cotton).

“…Dye molecules are composed of two components, chromophores and auxochromes. 4,5 Chromophores are unsaturated functional groups which are responsible for the color of dyes and auxochromes are functional groups (e.g., -COOH, -OH, -OR, -NH 2 ), covalently connected to chromophores which can further tune the color and often help to increase the solubility of dyes. Dyes are classified as neutral, cationic and anionic dyes based on the charge present on the chromophores.…”

“…The general objective of this research is to trap the colorant present in wastewater from dyeing processes by introducing a third element into the same bath. Some compounds or materials are known to be of use in this process, such as cyclodextrins [1], agricultural waste elements [2], and nanocomposites [3]; physical media, such as membrane filtration [4], among many other methods, can also be utilized.…”

Uses of Nanoclays and Adsorbents for Dye Recovery: A Textile Industry Review

et al. 2021

View full text Add to dashboard Cite

Wastewater recovery is one of the most pressing contaminant-related subjects in the textile industry. Many cleaning and recovery techniques have been applied in recent decades, from physical separation to chemical separation. This work reviews textile wastewater recovery by focusing on natural or synthetic nanoclays in order to compare their capabilities. Presently, a wide variety of nanoclays are available that can adsorb substances dissolved in water. This review summarizes and describes nanoclay modifications for different structures (laminar, tubular, etc.) to compare adsorption performance under the best conditions. This adsorbent capacity can be used in contaminant industries to recover water that can be used and be recontaminated during a second use to close the production circle. It explores and proposes future perspectives for the nanoclay hybrid compounds generated after certain cleaning steps. This is a critical review of works that have studied adsorption or desorption procedures for different nanoclay structures. Finally, it makes a future application proposal by taking into account the summarized pros and cons of each nanoclay. This work addresses contaminant reuse, where part of the employed dyes can be reused in printing or even dyeing processes, depending on the fixing capacity of the dye in the nanoclay, which is herein discussed.
