“…In addition to the removal of traditional pollutants such as suspended solids, organic matter and nutrients (Zhang et al 2014a(Zhang et al , 2014bMachado et al 2017;Arden & Ma 2018), CWs are capable of removing organic and inorganic pollutants (Verlicchi & Zambello 2014;Krzeminski et al 2019). Among these, the removal of pesticides (Barceló & Petrovic 2008), heavy metals (Wang et al 2017), pharmaceuticals (Li et al 2014;Zhang et al 2014aZhang et al , 2014bIlyas & van Hullebusch 2019;Zraunig et al 2019) and various other contaminants of emerging concern (CEC) (Imfeld et al 2009;Matamoros et al 2010;Gorito et al 2017;Talib & Randhir 2017) have been explored in the last decade. The observed removal of heavy metals was between 23 and 97% depending on the heavy metal, CWs' type, type of water matrix and others (Malaviya & Singh 2012).…”

A review of nature-based solutions for urban water management in European circular cities: a critical assessment based on case studies and literature

Nature-based solutions (NBS) can protect, manage and restore natural or modified ecosystems. They are a multidisciplinary, integrated approach to address societal challenges and some natural hazards effectively and adaptively, simultaneously providing human well-being and biodiversity benefits. NBS applications can be easily noticed in circular cities, establishing an urban system that is regenerative and accessible. This paper aims to offer a review on NBS for urban water management from the literature and some relevant projects running within the COST Action ‘Implementing nature-based solutions for creating a resourceful circular city’. The method used in the study is based on a detailed tracking of specific keywords in the literature using Google Scholar, ResearchGate, Academia.edu, ScienceDirect and Scopus. Based on this review, three main applications were identified: (i) flood and drought protection; (ii) the water-food-energy nexus; and (iii) water purification. The paper shows that NBS provide additional benefits, such as improving water quality, increasing biodiversity, obtaining social co-benefits, improving urban microclimate, and the reduction of energy consumption by improving indoor climate. The paper concludes that a systemic change to NBS should be given a higher priority and be preferred over conventional water infrastructure.

In addition, aspects such as the use of hybrid systems (Grandclément et al, 2017), impact on membrane fouling (Besha et al, 2017) sorption and biotransformation (Alvarino et al, 2018), geographical distribution (Tran et al, 2018), and comprehensive strategies for managing CEC (Talib and Randhir 2017) were also reviewed.…”

“… 1 In general, the water color is a primary indicator of its quality, and it is a fact that even a minute amount of dye (below the 1 ppm range) in water becomes evident by its color and therefore can be considered as not suitable for drinking or maintenance of ecosystems. 2 Because of the increased pollution of synthetic dyes in the environment, the most prominent one to suffer is the aquatic system as the increased levels of dyes in water cause the inadequate passage of natural sunlight. Under such conditions, the photosynthetic metabolism of aquatic life gets strongly interrupted and cannot sustain in the presence of toxic dye constituents.…”

Surface-Enhanced Biocompatibility and Adsorption Capacity of a Zirconium Phosphate-Coated Polyaniline Composite

et al. 2021

The present study deals with the synthesis, characterization, and testing of a novel composite, zirconium(IV) phosphate-coated polyaniline (ZrPO 4 @PANI), toward the adsorption- and surface-controlled toxicity applications. Following the synthesis of the ZrPO 4 @PANI composite using the sol–gel route, various characterization techniques such as Fourier transform infrared spectroscopy, scanning electron microscopy, and powder X-ray diffraction were employed to confirm its surface functionality, morphology and agglomeration, and crystallinity and crystal nature, respectively. The composite was found to be effective toward the adsorptive removal of the methylene blue dye (an organic pollutant) as against the changes in the dye concentration, dose, pH, and so forth. Also, to understand the MB adsorption kinetics, the experimental data were evaluated using the Langmuir and Freundlich models and the results were described in accordance with the Langmuir isotherm model (an adsorption capacity of 120.48 mg/g at ambient temperature). In addition, the tests conducted using pseudo-first- and pseudo-second-order kinetic models confirmed the existence of pseudo-second-order rates. Furthermore, the calculation of thermodynamic parameters for the MB adsorption, namely, changes in enthalpy, entropy, and Gibbs’ free energy, exhibited a spontaneous, feasible, and exothermic nature. Finally, the comparative studies of in vitro toxicity and flow cytometry confirmed that the copresence of ZrPO 4 along with PANI significantly improved the biocompatibility. The outcome of the experimental results implies that the composite is capable enough of serving as the safe and low-cost adsorbent, in addition to supporting the effective capping of the surface toxicity of PANI.
