et al.

Abstract: A molecularly imprinted polymer membrane (MIPM) was prepared using PVDF as the support and phenytoin (PHT) as a single template. The results indicated that the MIPMs can be used to extract PHT, phenobarbital, and lamotrigine in different matrices.

Phosphorus (P) fertilizer is an essential component of our food system with the majority of all mined P rock processed to make mineral fertilizers. Globally however P rock stocks are declining�both in quality and quantity�with poor P management creating a linear economic system where P is mined, globally redistributed into products and eventually discharged into the environment leading to eutrophication. To enable establishment of a circular P economy, whereby P can be recovered from waste for its industrial reuse, requires the development of effective P recovery technologies. Adsorption via anion exchange is a promising technology for P recovery from waste streams; however, in many cases, the regeneration of the sorbent used (to allow for its subsequent reuse) has not been extensively investigated. We now describe a gel-type anion exchange polymer composed of vinyl benzyl chloride, hydroxypropyl methacrylate, and ethylene glycol dimethacrylate synthesized via suspension polymerization. The obtained material was modified to introduce a quaternary ammonium functionality, characterized, and tested for phosphate capture, in the presence of competing anions and from wastewater samples. Fixed-bed experiments were conducted using monobasic phosphate as adsorbate to test polymer performance, and its stability upon repeated adsorption/desorption cycles was investigated by solid-state NMR, revealing that no degradation or loss of P binding performance across 50 regeneration cycles. Excellent polymer performance in the recovery of P from wastewater was also demonstrated.
