Descrizione generale

Hexadecyltrimethylammonium bromide is a titrant for the potentiometric titration of perchlorate with ionselective electrodes.

Applicazioni

<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>

Cetyltrimethylammonium bromide is used in the precipitation titration of perchlorate, with potentiometric end-point detection. A perchlorate, fluoroborate or nitrate ion-selective electrode may be used. The method is more sensitive than the commonly used titration with tetraphenylarsonium chloride. It can be

At elevated temperatures, bimetallic nanomaterials change their morphologies because of the interdiffusion of atomic species, which also alters their properties. The Kirkendall effect (KE) is a well-known phenomenon associated with such interdiffusion. Here, we show how KE can manifest in

The biocide chlorhexidine (CHX) as well as additional membrane-active agents were shown to induce expression of the mexCD-oprJ multidrug efflux operon, dependent upon the AlgU stress response sigma factor. Hyperexpression of this efflux system in nfxB mutants was also substantially

Biocompatible cationic surfactants from the amino acid lysine (hydrochloride salts of N(epsilon)-lauroyl lysine methyl ester, N(epsilon)-myristoyl lysine methyl ester and N(epsilon)-palmitoyl lysine methyl ester) have been prepared in high yields by lysine acylation in epsilon position with three natural saturated

Photocatalytic reduction of aqueous Cr(VI) was successfully achieved on nanostructured SnIn(4)S(8). The SnIn(4)S(8) particles with flower-like nanostructure were synthesized via a facile solvothermal method. UV-vis diffuse reflectance spectra (DRS) indicated that the SnIn(4)S(8) particles had strong absorption in visible region
