“…These CS/BC composites have been employed as adsorbents in a number of studies to remove heavy metal ions from water [ 264 ], including Cr(VI) [ 265 ]. In addition, they have been utilised in the removal of phosphates [ 266 ], nitrates and phosphates [ 267 ], fluorides [ 268 ], benzoates [ 269 ] and various antibiotic and pharmaceutical molecules, such as diclofenac, ibuprofen and naproxen [ 270 ], ciprofloxacin [ 271 , 272 ] and ofloxacin [ 273 ].…”

The quality of water is continuously under threat as increasing concentrations of pollutants escape into the aquatic environment. However, these issues can be alleviated by adsorbing pollutants onto adsorbents. Chitosan and its composites are attracting considerable interest as environmentally acceptable adsorbents and have the potential to remove many of these contaminants. In this review the development of chitosan-based adsorbents is described and discussed. Following a short introduction to the extraction of chitin from seafood wastes, followed by its conversion to chitosan, the properties of chitosan are described. Then, the emerging chitosan/carbon-based materials, including magnetic chitosan and chitosan combined with graphene oxide, carbon nanotubes, biochar, and activated carbon and also chitosan-silica composites are introduced. The applications of these materials in the removal of various heavy metal ions, including Cr(VI), Pb(II), Cd(II), Cu(II), and different cationic and anionic dyes, phenol and other organic molecules, such as antibiotics, are reviewed, compared and discussed. Adsorption isotherms and adsorption kinetics are then highlighted and followed by details on the mechanisms of adsorption and the role of the chitosan and the carbon or silica supports. Based on the reviewed papers, it is clear, that while some challenges remain, chitosan-based materials are emerging as promising adsorbents.

“…Therefore, surface water must be treated and purified to meet standard human consumption limits. Coagulants are chemicals (aluminum sulfate, aluminum chloride, ferrous sulfate and ferric chloride) or plant-derived coagulants, which are substances used to remove water pollutants, such as color, turbidity and organic matter from raw (unfiltered) water by forming large aggregates that finally settle to the bottom of the container (Nguyen et al, 2020). Recently, many research insisted that plant-based coagulants (likely Moringa oleifera, Cicer arietinum, Dolichos lablab and pinecones) are the suitable and safer treatment alternatives for these chemicals Hoa and Hue, 2018;Nath et al, 2021).…”

<p>This goal of this study was to evaluate the effectiveness of a new coagulant extract from pumpkin seeds (PSC) for removing turbidity and organic compounds from different natural surface waters. Two design experiment methods, namely central composite design (CCD) and response surface methodology (RSM) were used to optimize PSC for removal of turbidity and organic matter via the chemical oxygen demand (COD) of surface water. The CCD results indicated that more than 74.7% of COD and 94.4% of nephelometric turbidity unit (NTUs) were removed under optimized conditions (pH = 7.4; mPSC = 1.5 g/L; time: 88 min). They allowed for final effluent with significantly higher quality in terms of organic content and safe to Vibrio fischeri to be obtained</p>
