Application

Potassium hydrogen phthalate may be used as a buffering agent or as a standard for total organic carbon (TOC) calibration and may be used to asses the oxidating activity of CNTs/TiO(2) photoanodes. Potassium hydrogen phthalate solution may be used as a liquid filter to reduce the effects of Rayleigh scattering on collected Raman spectra.

Because of the occurrence of ion exchange between high-ionic-strength solution and anions of polymeric ionic liquids (PILs), PILs based solid-phase microextraction (SPME) fibers were rarely used in direct immersion mode to high-salt-added samples. In this work, a novel double-confined PIL
