Fast and simultaneous removal of microplastics and plastic-derived endocrine disruptors using a magnetic ZIF-8 nanocomposite

Exploring the Potential of Amino-Functionalized Zeolite Series/H3PO4-Biochar for Environmental Microplastic Removal

“…The implication of this is that the PSMM molecules filled the active sites of AFZ increasingly as its surface became deprotonated, with a reduction in the active sites available on the surface of AFZ. Thereafter, there was decrease in the uptake of PSMMs by AFZ at pH > 7.0. ,, It is understood that polystyrene particles are negatively charged based on their surfaces, irrespective of the fact that they are not specifically functionalized. This property favored the uptake of PSMMs by AFZ below the ZP of 7.3 …”

“…Therefore, the uptake of PSMMs by AFZ was a combination of chemisorption and physisorption. It occurred that the molecules of PSMMs filled the single-existing active sites of AFZ first before filling its combined active sites. , …”

“…Among these technologies, adsorption technology is the simplistic, efficient, and cost-effective technology applied for water treatment due to the fact that it minimizes reactive chemical intermediates and secondary byproducts, no special technique is needed, and it is effective. In recent times, few publications are available in literature for the application of adsorption technology for the removal of MPs in water. − …”

“…To date, few research works are available in literature that reported the application of adsorbents for the removal of MPs from contaminated water. − ,,, These adsorbents utilized in the literature are expensive and readily unavailable and thus may cause limitations in their usage. This study addressed this pitfall such that a low-cost adsorbent from a cheap and ubiquitous source was used for the removal of polystyrene monodispersed microsphere suspensions (PSMMs) from contaminated water.…”

“…In general terms, studies have indicated that wastewater treatments plants remove the majority of MPs, achieving removal efficiencies of 98-99% [8,9]. Among the conventional physico-chemical treatment methods used in the removal of these pollutants there are sand filtration [10], coagulation-flocculation [11], membrane bioreactor [12], electrocoagulation [13] and sorption [14]. Despite the high removal ability of the wastewater…”
