“…Wang et al [124], Zeng et al [125], and Nazarizadeh et al [126] reported heavy metal removal by modified organoclay. The removal of dyes from polluted water has been reported by Dai et al [127], Zhao et al [128], and Ly et al [129]; chlorine contamination in water being removed by Iranian bentonite was reported by Moradi et al [130]. From the chronological data and the trend, it can be deduced that, in all cases, organoclay was predominantly used for the removal of aqueous pollutants.…”

Natural clay mineral and its modifier called modified clay have been used in many environmental applications for a number of years. However, they are not capable enough to achieve a higher conversion rate and so-called ecological sustainability. This can be due to a lack of understanding of the selectivity of the clay and its modifier or a lack of compatibility between clay and pollutants. Recently, the development and implementation of green principles into practice have become an emerging field that brings together green chemistry and engineering practices to achieve a pollutant-free environment (air, water, and soil). This review summarizes the role of clay/modified clay in pollution control and discusses the role of green chemistry in creating global sustainability. In this context, this review sheds light on the complete classification of the clay family to identify its properties and to critically examine the applicability of clay and modified clay for air, water, and soil pollution control over the past decade. This is the unique point of this review, showing how the properties of clay/modified clay can be useful for removing any type of pollutant without focusing on a single type of pollutant or clay. Furthermore, the importance of green materials in clay research, as well as the future area of application, was discussed. Overall, this review places value on multidisciplinary researchers to determine the role of the green pathway in the application of clay and modified clay in achieving environmental sustainability.

“…Subrahmanya and his coworkers [69] reported a syringe flter membrane composed of Whatman 42 flter, GO 10 /(SBA-15/ PDA) 2 membrane to efectively screen MB and EBT dyes from wastewater. PVDF/IL-Na + MMT membrane is fabricated by Zhao et al [70] for removal efciency for both anionic and cationic dyes at a high level of over 90% efciency. Li et al [71], in their study, prepared a novel antifouling loose nanofltration (LNF) membrane by crosslinking and grafting of hydrolyzed polyacrylonitrile ultrafltration substrate with a PEI-based zwitterionic polymer PEI-CA through the covalent amide bond for the treatment of dye brilliant blue R, CR, MB, and chrome black T. Dmitrenko et al [72] reported PAN membranes by various TiO 2 modifcations [72].…”

In recent decades, the textile industry has contributed to continuous pollution in the environment. Synthetic dyes which are commonly found in waste water are azo, sulfur, anthraquinone, triphenylmethyl, indigoid, and phthalocyanine derivatives. These pollutants block the light penetration in water bodies and prevent photosynthesis activity, thereby affecting aquatic life. As an environmental crisis, several technologies have been explored to control pollution. Among all the techniques, the photocatalysis process is considered as a green, simple, and economical process. To improve the photocatalytic activity, researchers worldwide have investigated various photocatalysts such as metal oxides, metal ferrites, and heterostructured nanocomposites. The major goal of this review article is to propose a high-performing, cost-effective hybrid photocatalyst reported to date for prospective azo dye pollutant remediation. This review article also aimed to highlight the challenges and uncertainties associated with dye degradation in the photocatalytic process.

In this study, the dual strategy of 1-butyl-3vinylimidazolium bromide ionic liquid (IL) grafting and carbon nanotubes (CNTs) nanocomposition was applied to modify poly(vinylidene fluoride) (PVDF)-based membranes. The highly hydrophilic/oleophobic and fouling-resistant PVDF-g-IL/CNTs membranes with excellent separation efficiency were obtained by the nonsolvent-induced phase separation method with ethanol− water mixed solution as the coagulation bath. The grafted IL not only generated hydrophilic groups on PVDF chains but also acted together with the CNTs to induce the formation of hydrophilic βcrystalline phase of PVDF, which significantly improved the hydrophilicity and pore structure of the modified PVDF membranes. As a result, the pure water flux of the optimal membrane increased up to 294.2 L m −2 h −1 , which was 5.2 times greater than that of the pure PVDF membrane. Simultaneously, the electrostatic interaction of the positive IL and the integration of CNTs enhanced adsorption sites of the membranes, producing exceptional retention and adsorption of dye wastewater and oil−water emulsion. This study presents a straightforward and efficient approach for fabricating PVDF separation membranes, which have potential applications in the purification of various polluted wastewater.
