Luminescent determination of nitrite traces in water solutions using cellulose as sorbent

Abstract

Morphology and photoluminescence (PL) properties for microcrystalline cellulose (MCC), microcrystalline nitrite powders of common formulae MNO 2 (M = Na, K) (MCN) and two-component materials composed of both MCC and MCN have been prepared and characterized by means of optical microscopy and luminescence spectroscopy. This study aimed to clarify a possibility of low-limit determination of the nitrite traces in water solutions by luminescent method.Published by Copernicus Publications on behalf of the AMA Association for Sensor Technology.

Structure and Properties of Microcrystalline Cellulose "Ceramics-Like" Composites Incorporated with LaVO4:Sm Oxide Compound

“…The described data are similar to ones earlier reported by us for the microcrystalline cellulose samples and some other "cellulose-oxide" composites [12,13,16]. Besides, mentioned characteristics are similar to those published elsewhere concerning luminescence of various cellulosebased materials [5,[8][9][10].…”

“…At the same time, they are of interest as materials for applications in electronic and opto-electronic devices, e.g. such as solar cells, supercapacitors, lithium-ion batteries, flexible "paper" electronics [5][6][7] and luminescent materials [8][9][10] particularly for their potential applications as chemical and biological sensors or for toxic chemical removing [11][12][13].…”

Polymer-Oxide Composites: Toward New Optical Materials

“…We denote the composites of such type here as W-NaNO 2 and W-CsNO 3 . The details both of the oxides synthesis and the samples preparation can be found in [36,37,44,48,49].…”

“…Those were scanning electron microscopy (SEM), chemical elements analysis, X-ray diffractometry (XRD), luminescence spectroscopy and dielectric characteristics measurements. Equipment and any other details of experimental study can be found also in [36,37,44,48,49].…”

“…These PMM/NCs are sustainable and renewable materials and paid great attention in biomedical technologies (membranes and filters, scaffolds, antimicrobial films, pharmaceuticals, drugs delivery, etc. [31][32][33][34]) or as adsorbents for toxic chemicals removing [35][36][37]. Due to their mechanical flexibility they can be useful in manufacturing of the electronic and opto-electronic devices (solar cells, super-capacitors, lithium-ion batteries, "paper" electronics [38][39][40], luminescence sensors [41][42][43]).…”
