Abstract Mn2O3-Fe2O3 catalyst was fabricated from spent alkaline batteries and used for effective elimination of acetaminophen (APAP) by activating peroxymonosulfate (PMS). APAP removal at various initial pH, its degradation pathway and the stability of catalyst were investigated.

Values of the Ostwald solubility coefficient of gases and vapours in methanol solvent, LMeOH, at 298 K have been determined for 23 solutes by an indirect method in which experimental partition coefficients between methanol and hexadecane were combined with literature data on Ostwald solubility coefficients in hexadecane.

The partitioning of organic compounds between air and foliage and between water and foliage is of considerable environmental interest. The purpose of this work is to show that partitioning into the cuticular matrix of one particular species can be satisfactorily modeled by general equations we have previously developed and, hence, that the same general

A merocyanine dye equipped with a Hamilton-receptor unit has been synthesized that enables strong noncovalent binding of other merocyanine dyes bearing barbituric acid acceptor groups by six hydrogen bonds. NMR and UV/vis titration experiments in toluene, chloroform, dichloromethane, dioxane, and THF provide evidence for the formation of 1:1 complexes ...

Abstract The solubility of carbon dioxide was determined in dimethyl sulfoxide, ethylene glycol, and their binary mixtures at the temperatures ranging from 298.15 Kto 328.15 K and the pressures ranging from (0 to 6) bar (0 to 0.6 MPa). It was shown that the solubility of CO2 increased with the increasing of pressure while decreased with the ...

Literature values of the in vivo distribution (BB) of drugs from blood, plasma, or serum to rat brain have been assembled for 207 compounds (233 data points). We find that data on in vivo distribution from blood, plasma, and serum to rat brain can all be combined.

The linear free energy relationship (LFER) analysis based on the Hammett equation has been applied for dissociation processes of 8-hydroxyquinoline and its derivatives in aqueous and 1,4-dioxane-water solutions. The effects of temperature, composition, and ionic strength of the solutions have been discussed.

Characterization of Some GLC Chiral Stationary Phases: LFER Analysis
Analytical Chemistry, 1997Linear free energy relationships (LFERs) have been used to characterize 19 chiral stationary phases (CSPs) using retention data of Berthold et al. (Anal. Chem. 1995, 67, 849−857); of the 19 chiral phases, 17 were cyclodextrin derivatives. Most of the CSPs had moderate-to-large dipolarity/polarizability and considerable hydrogen bond basicity. Of the 19

Cytotoxicity data of anti-HIV 5-phenyl-1-phenylamino-1H-imidazole derivatives were subjected to quantitative structure-activity relationship (QSAR) study using linear free energy related (LFER) model of Hansch using electronic (Hammett sigma), hydrophobicity (pi) and steric (molar refractivity and STERIMOL L, B1, B2, B3 and B4) parameters of phenyl ...
