Lead(II) Extraction with Electrospun Spiropyran Functionalized PMMA Nanofibers

Creator:: Fuchs, Brian K.
Abstract:: A system to reversibly extract Pb²⁺ ions from aqueous solutions using spiropyran functionalized nanofibers was proposed. Spiropyrans are photochromic compounds which undergo a conformational change that alters their physical properties and makes Pb²⁺ binding possible upon irradiation with UV light (365 nm). Irradiation with green light (525 nm) reverses this...

Improvements in synthesis and response techniques of ion-selective sensors

Creator:: Pylypiuk, Nataliia
Abstract:: Two improvements to the established procedures for synthesis and response detection of ion-selective optical sensors (optodes) were introduced. The first improvement addresses the drawback of organic dye (optode-localized chromoionophore) photobleaching. This positively impacts fluorescence response and allows for (1) direct measurement of hydrogen ion activity upon binding with the dye,...
