Abstract:Mesoporous silica materials have been widely used as gas adsorbents due to their excellent adsorption ability, large specific surface area, simple preparation process, and convenient functionalization. In this study, a core–shell mesoporous material MCM-41@SiO2 was synthesized and functionalized by CoCl2, and subsequently KSCN, to prepare an ammonia adsorbent. The adsorbent was proved to possess high surface area, good sphericity, uniform size, good dispersibility, and high adsorption capability following DLS,… Show more
“…2 Similarly, Nessler tubes have also been utilized for colorimetric detection. 59 In modern colorimetric analysis, UV-vis spectrophotometers are commonly employed, and analyte concentrations are quantified using the Beer-Lambert Law. 2,60 The colorimetric mechanism of iodide sensing using nanoparticles involves specific changes in their optical properties, such as color or absorbance, in response to the presence of iodide ions.…”
