Tereshchenkova, Anna A. published the artcileSolid-phase extraction of lanthanum on modified low-polarity sorbents, Product Details of C17H14N2O2, the publication is Vestnik Moskovskogo Universiteta, Seriya 2: Khimiya (2013), 54(4), 203-209, database is CAplus.
Preconcentration of lanthanum on various low-polarity sorbents (hexadecyl-silica, hyper cross-linked polystyrene, polyvinylidene difluoride, activated carbon) dynamically coated with 1-phenyl-3-methyl-4-benzoylpyrazol-5-one (PMBP) was studied. Reagent and lanthanum distribution coefficients were evaluated under dynamic conditions. Reagent elution was studied. Recovery of lanthanum with coated and uncoated sorbents was studied. Efficiency of desorption with nitric acid solutions or ethanol was studied.
Vestnik Moskovskogo Universiteta, Seriya 2: Khimiya published new progress about 4551-69-3. 4551-69-3 belongs to pyrazoles-derivatives, auxiliary class Benzenes, name is 4-Benzoyl-5-methyl-2-phenyl-2,4-dihydro-3H-pyrazol-3-one, and the molecular formula is C10H10N2, Product Details of C17H14N2O2.
