Utilization of a plasticized PVC optical sensor for the selective and efficient detection of cobalt(ii) in environmental samples

Abstract

A novel sensitive, selective, and reversible cobalt(ii) ion optical sensor was prepared by the incorporation of [CPDB] and (NaTPB) in a (PVC) membrane containing (DOA) as a plasticizer.

Optical chemical sensor of Gd(iii) based on 5-(2′-bromophenyl- azo)-6-hydroxypyrimidine-2,4-dione immobilized on poly(methyl methacrylate) and 2-nitrophenyloctylether matrix

“…In our Laboratory, various strategies for optical sensors for different metal ions in aqueous samples have been illustrated. [32][33][34][35][36][37][38] The comparison of UV-vis spectra of optode samples equilibrated with diverse aqueous matrix having same concentration of Gd(III) (150 ng mL À1 ) is shown in Fig. 1.…”

“…Therefore, a practical, affordable approach that can provide the selectivity to detect Gd(III) in the presence of other, extremely similar lanthanides is essential. [25][26][27][28][29][30][31] In our Laboratory, various strategies for optical sensors for different metal ions in aqueous samples have been investigated, [32][33][34][35][36][37] since they can easily be included in low-cost, user-friendly kits. Additionally, they can offer the required sensitivity and selectivity for environmental checking.…”

Pilot Study on the Visualization of Latent Fingerprints and Naked Eye Detection of Hg2+ and Zn2+ Ions in Aqueous Media Using Ninhydrin-Based Thiosemicarbazone

“…1−3 Due to the employment of "low-tech" spectroscopic equipment to find significant chemical species in biological and environmental processes, selective optical sensing is generating a lot of interest. 4 Finding low concentrations of heavy metals in aqueous solutions is a crucial component of environmental monitoring. Mercury is one of the most crucial ions to study due to its toxicity to the ecosystem and negative effects on human health, such as those shown in Minamata illness and mercury poisoning in Iraq.…”

A novel sensor for the selective monitoring of trace ytterbium ions using an agarose-based optical membrane

“…[49][50][51][52][53] Spectrophotometric studies of complexes are preferred because of their low operating costs and simplicity. In our earlier reports, some optical sensors for Ag(I), 36 Zn(II), 37 Cr(III), 38 and Co(II) 39 evaluation in terms of covalent immobilization of coloured complexes in a suitable membrane were introduced. The goal of the present study is to successfully immobilize b-2hydroxybenzyl-5-bromo-2-hydroxyazastyrene on an agarose membrane lm to construct a novel optical sensor for Yb 3+ determination.…”

“…[26][27][28][29][30][31][32][33][34][35] Optical sensors have shown to be quite useful for analyzing several metal ions. [36][37][38][39][40][41][42] They are simple, quick, and affordable, and they can reliably respond to an extensive diversity of concentrations. According to a literature survey, there are just two reports on Yb 3+ sensors.…”
