Fast and efficient adsorption of bisphenols pollutants from water by using Hydroxypropyl-β-cyclodextrin polymer

High performance ultra- and nanofiltration removal of micropollutants by cyclodextrin complexation

“…The binding constant was measured with ITC calorimetry and determined assuming 1:1 complex formation between IBU and phenol guest molecules and HP-β-CD and β-CD polymer, as shown in Table 2, along with a literature value for the complexation between BPA and HP-β-CD. It should be noted that the HP-β-CD used in the literature value has a higher degree of substitution than the HP-β-CD used in the current study, hence there are a higher number of hydroxypropyl groups substituted on the CDs (Cai et al, 2020). The highest binding strength is observed between BPA and HP-β-CD (14940 M −1 ).…”

β-Cyclodextrin Polymer-Based Host–Guest Interaction and Fluorescence Enhancement of Pyrene for Sensitive Isocarbophos Detection

“…More severely, the continual assimilation by plants and enrichment in the food chain mean that even a very low concentration of organophosphorus pesticides could threaten human health, which raises people’s concern about their health effects. 4 , 5 There have been a large number of reports about organophosphorus pesticides being related to human diseases such as attention deficit hyperactivity disorder, Parkinson’s, amyotrophic lateral sclerosis, Alzheimer’s, chronic diseases of the central nervous system, etc. 6 Accordingly, it is urgent to develop highly sensitive methods for organophosphorus pesticide analysis in the field of food safety protection.…”

“…Organophosphorus pesticides have been widely applied throughout the world for their high efficiency in preventing diseases and pests from harming crops. − Nevertheless, they are highly neurotoxic because of their inhibition effect on acetylcholinesterase activity in the central and peripheral nervous system. More severely, the continual assimilation by plants and enrichment in the food chain mean that even a very low concentration of organophosphorus pesticides could threaten human health, which raises people’s concern about their health effects. , There have been a large number of reports about organophosphorus pesticides being related to human diseases such as attention deficit hyperactivity disorder, Parkinson’s, amyotrophic lateral sclerosis, Alzheimer’s, chronic diseases of the central nervous system, etc .

Sequestration of Phenols from Water into Poly(α-olefins) Facilitated by Hydrogen Bonding Polyisobutylene Additives

“…Phenolics are often byproducts of other industrial processes. − Whatever the source, these phenolics are generally highly toxic water pollutants, and a variety of procedures have been used to affect their removal from water. Common processes for removal of trace phenolics from water include oxidative degradation, biological treatments, flocculation, , liquid/liquid extraction, ,, or, most commonly, adsorption by solid supports. ,− In some cases, these procedures can be combined.…”

“…Adsorbents such as activated carbon are common, but molecularly designed polymeric sorbents that are more active and/or more easily regenerated than activated carbon have received much more attention recently. − Activated carbon is still the classic solid adsorbent for organic trace impurities and can be used for many phenols so long as the phenolic compound is neutral . However, recent studies have shown that solid absorbents tailored to sequester specific phenols including phenols such as BPA, NP, or phenols with various electron-donating and -withdrawing substituents have advantages over activated carbon. − ,− These newer organic solid supports are often superior to activated carbon because they use molecular recognition phenomena to remove specific phenols. For example, cross-linked β-cyclodextrin networks have been used for selective molecular absorption of BPA and other aromatic dyes that dock with cyclodextrin. ,, Likewise, NP can be removed from water by molecularly imprinted polymeric colloids .…”
