应用
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.
