Phosphorus sustainability: a case for phytic acid as a biorenewable platform

“…118 A reusable PA-functionalized poly- N -phenylglycine composite was synthesized and showed excellent adsorption of Cd( ii ) and Pb( ii ) from acidic solutions (pH 5.2), 119 while a polyurethane PA nanofibrous membrane demonstrated moderate adsorption of aqueous Pb( ii ) at pH 6. 120 Another reusable composite membrane of PA doped polyaniline/cellulose acetate demonstrated good adsorption capacity for Hg( ii ) and Cr( vi ) at pH 5.0 and 2.0 respectively, and importantly, the performance of this material was validated with simulated wastewater experiments. 121…”

Review of the Recent Advances in Electrospun Nanofibers Applications in Water Purification

“…In the last decade, many researchers have focused their work on removing the inorganic pollutants from wastewater using nanofibers fabricated via the electrospinning technique, as shown in Table 2 [7][8][9]. As such, multifunctional electrospun nanofibers have been fabricated and widely utilized in the last few years to remove various types of inorganic pollutants, such as lanthanides and actinides [7,93,94], Pb 2+ (with other metals ions) [95][96][97][98][99][100][101][102][110][111][112][113][114][115]118,119,121], Cu 2+ [8,9,[102][103][104][105]117,120], Cd 2+ [106-108], Ni 2+ [109], Cd 2+ , Zn 2+ [116], Ca 2+ , Mg 2+ [122], heavy metals [123,124], Cr 6+ [125][126][127][128][129][130][131][134][135]…”
