Web3 mei 2024 · We present a novel method for the measurement of lithium isotopes in garnet utilising glass reference materials and secondary ion mass spectrometry (SIMS). Measured lithium isotopic compositions of natural garnets are heterogeneous, making them unreliable reference materials for in situ determination. WebIn this study compound-specific isotope analysis (CSIA) has been used to explore the degradation mechanism of nano titanium dioxide (TiO 2) catalyzes photodegradation of diethyl phthalate (DEP).TiO 2 is a popular photosensitizer with potential in waste water treatment and application in advanced oxidation processes. The degradation process of …
