Beschreibung

Allgemeine Beschreibung

Titrant for the potentiometric titration of perchlorate with ionselective electrodes

Anwendung

<ul>
<li><strong>Sensitive detection in spectroscopy:</strong> The surface-active properties of Hexadecyltrimethylammonium bromide enhance the FRET effect in Cu-doped NH2-MIL-88(Fe), used for the highly sensitive detection of 3-nitro-L-tyrosine in biomolecular spectroscopy, contributing to advancements in diagnostic techniques and chemical analysis (Xu et al., 2024).</li>
<li><strong>Stabilization of heavy metals:</strong> Utilized in the intercalation-exfoliation modification of vermiculite for the stabilization of heavy metals during the pyrolysis of solid waste and sludge, Hexadecyltrimethylammonium bromide shows potential in waste management and pollution control, contributing to safer environmental practices (Yang et al., 2024).</li>
