“…For a favourable adsorption, 0 < n < 1, while n > 1 represents an unfavourable adsorption, and n = 1 indicates a linear adsorption [58]. A larger n value means that the system is more heterogeneous, which usually results in non-linearity of the adsorption isotherm [59]. A Freundlich exponential coefficient (n) in the range from 0.71 to 1.15 is newly reported for the adsorption of triclosan on pristine polystyrene nanoparticles.…”

environmental studies that assessed the abundance of microplastics in different water columns [8]. Release of nanoplastics from drinking water bottles was characterized by SEM, XPS, SPES and µ-Raman Analysis [9]. Spherical organic nanoparticles from bottled water were collected effectively through a tangential flow ultrafiltration system [10]. Polyethylene terephthalate nanoplastics collected from commercially bottled drinking water were detected with an average mean size of 88 nm; their concentration was estimated to be 10 8 particles/mL by nanoparticle tracking analysis [11]. A new study has reported the levels of micro-and nano-particles released in carbonated beverage bottles range from 68 to 4.7×10 8 particles/L, potentially posing health risks to humans. Polypropylene bottles released more particles than polyethylene terephthalate and polyethylene bottles [12]. The occurrence of micro-and nano-plastics (with particle diameters from 0.7 to 20 μm) in plastic bottled water has been assessed, and the median concentration was 359 ng L −1 . Polyethylene was the most detected polymer, while polyethylene terephthalate was found at the highest concentrations [13]. The content of microplastic and nanoplastic particles in raw water, tap water, and drinking water was analyzed. Plastic particles were found in all water samples, with an average abundance ranging from 204 to 336 particles/L in raw water, from 22 to 33 particles/L in tap water, and from 25 to 73 particles/L in drinking water [14].

Phosphorus is a nutrient that is required for life. Eutrophication, on the other hand, is caused by an overabundance of phosphorus in the hydrosphere. Eutrophication is a form of water pollution that can be solved by removing phosphorus from the environment. Adsorption with cation exchange resin is a more practical method for removing phosphate ions at low concentrations than traditional approaches. The column approach is good for recovering phosphate effectively. As a result, a superior adsorption ability of the column and a practical regeneration process are critical. Accordingly, the goal of this study is to design a phosphate ion recovery system using a Fe-type cation exchange resin (Fe3+-type UBK 10) column. The batch approach was used to investigate the characteristics influencing the adsorption of phosphate ions on Fe-type UBK 10 in order to better comprehend the mechanism of adsorption. The number of phosphate ions adsorbed increased with increasing reaction time, according to the findings. The best results were achieved using 3 g of resin in 0.05 M NaCl at pH 6. The best fit was found in the Langmuir isotherm using equilibrium data.

Activated carbon was prepared from coconut shell, an agricultural waste, for the removal of phosphorus from synthetic phosphorus‐containing wastewater. The activated carbon obtained from the coconut shell was characterized using Fourier‐transform infrared (FTIR) spectroscopy. Batch mode experiments were conducted to study the effects of pH, particle size, adsorbent dosage, and sorption time on the adsorptive potential of the prepared activated carbon. Response surface methodology was employed to study the interactions among the variables and to optimize the process conditions for the maximum removal of phosphorus using the coconut shell–based activated carbon (CNS). The characterization results from the FTIR showed the presence of variety of functional groups, such as −OH, −NH, C=O, C−H, C−N, CH3, and CH2, which explains the CNS's improved adsorption behavior on the colloidal particles. A maximum performance of 95.22% was obtained for CNS at the optimum conditions of adsorbent dosage = 1,000 milligrams (local variable), pH 2 (local variable), particle size = 0.2 millimeters (local variable), and sorption time = 4.2 hours (global variable).
