“…Conductometric titrations have a more selective character when acid-base, complexometric or precipitation reactions are explored [16][17][18], thus widening the range of analytical applications. Pantel and Weisz had developed conductometric and high-frequency conductometric methods for the determination of endpoint of catalytic titrations [19]. A simultaneous conductometric titration method for determination of mixtures of acetic acid, monochloroacetic acid, and trichloroacetic acid based on the multivariate calibration partial least squares was proposed by Ghorbani et al [20].…”

A modified Ti/(SnO2+ Sb2O3) electrode was prepared by thermal deposition on titanium substrate and its use as indicator electrode to potentiometric and conductometric acid-base titration in aqueous solution at 298 K was developed. The E-pH curve is linear with slope of 0.0512 V/dec at 298 K. The standard potential of this electrode,E0, was determined with respect to the SCE as reference electrode. The recovery percentages for potentiometric and conductometric acid-base titration for acetic acid against NaOH were calculated. The cell constant, specific conductance, and the molar conductance with dilution for some common electrolytes were measured.

Rapid and selective sensing of sulfur dioxide (SO) gas has attracted more and more attention because SO not only causes environmental pollution but also severely affects the health of human beings. Here we report an amino-functionalized luminescent metal-organic framework (MOF) material (i.e., MOF-5-NH) and further investigate its sensing property for SO gas and its derivatives as a luminescent probe. The results indicate that the MOF-5-NH probe can selectively and sensitively sense SO derivatives (i.e., SO) in real time by a luminescence turn-on effect with a lower detection limit of 0.168 ppm and a response time of less than 15 s. Importantly, the luminescence turn-on phenomenon can be observed by the naked eye. We also assembled MOF-5-NH into a test paper to achieve the aim of portable detection, and the lower-limit concentration of the test paper for sensing SO in real time was found to be about 0.05 ppm. Moreover, MOF-5-NH also shows good anti-interference ability, strong luminescence stability, and reusability, which means that this material is an excellent sensing candidate. The amino functionalization may also provide a modification strategy to design luminescent sensors for other atmospheric pollutants.
