애플리케이션

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.

Urinary phthalate excretion is used as marker of phthalate exposure in epidemiological studies. Here we examine the reliability of urinary phthalate levels in exposure classification by comparing the inter- and intrasubject variation of urinary phthalate metabolite levels.

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

High-molecular-weight phthalates in indoor dust have been associated with asthma in children, but few studies have evaluated phthalate biomarkers in association with respiratory outcomes. We explored the association between urinary concentrations of phthalate metabolites and current asthma. In a cross-sectional
