Environmental pollution is a global concern due to the rapidly increasing population and industrialization. In this context, there strong need develop green separation techniques isolate pollutants from different sources. Polymer assemblies or hydrogel polymers are water-swollen crosslinked polymeric materials capable of retaining large amounts water in their 3D networks. Hydrogels function as excellent adsorbents pollutant removal processes by binding heavy metal ions and/or organic...
The use of electronic cigarettes (ECs) is recognized as a source many pollutants, just like conventional (CCs). analysis EC aerosol samples has confirmed the presence various metallic species. Most these metals originate from parts cartomizer, e.g., solder joints, wires, and silicate beads. metal concentration levels in were shown to be generally two four orders magnitude lower than those CCs. However, ECs can still pose significant human health hazards consumers are exposed toxicity other...
This article describes a newly designed block copolymer based aqueous biphasic system (ABS, composed of two immiscible phases) which is further utilized to study extraction behavior three iodine species <italic>viz.</italic>, I<sub>2</sub>, I<sup>−</sup>, and IO<sub>4</sub><sup>−</sup>.
The present article reports on the speciation of As(V) and As(III) using aqueous biphasic extraction based a polyethylene glycol–salt system. For detection these inorganic arsenicals salts are converted to their respective arsenomolybdenum blues having formulae [AsVMo4V Mo8VIO40]7− [AsIIIMo4V Mo8VIO40]9− measured for absorption spectra at 820 nm. These blue species different in behaviour with Once solutions formed they could further find application nitrite nitrate solution. A high molecular...
Adsorption-desorption behaviors of polar and nonpolar volatile organic compounds (VOCs), namely, isopropanol nonane, on mesoporous silica were studied using optical reflectance spectroscopy. Mesoporous was fabricated via electrochemical etching silicon subsequent thermal oxidation, resulting in an average pore diameter 11 nm a surface area approximately 493 m2/g. The thickness the porous layer, which is proportional to number adsorbed molecules, measured visible light interferometry. In situ...
