Modeling competitive cation exchange of aromatic amines in water-saturated soils.
Competitive association to several components of soil through ion exchange processes influences the fate of organic cations in the environment. To examine these processes, the distributions of aniline and 1-aminonaphthalene between aqueous 5 mM CaCl2 solutions and three different Indiana soils were evaluated. Solute ratios (Sr) of aniline to 1-aminonaphthalene of 0.4-4.7 were employed, and the ...
متن کاملBiodegradation of Polycyclic Aromatic Hydrocarbons (PAHs) in Petroleum Contaminated Soils
Polycyclic aromatic hydrocarbons are a class of potentially hazardous chemicals of environmental and health concern. PAHs are one of the most prevalent groups of contaminants found in soil. Biodegradation of complex hydrocarbon usually requires the cooperation of more than single specie. In this research biotreatment of PAH (phenanthrene) was studied in a solid-phase reactor using indigenou...
متن کاملNitrosamines and Aromatic Amines
A new method for the simultaneous determination of hemoglobin adducts from aromatic amines and tobacco-specific nitrosamines (TSNA) is described. After mild base-catalysed hydrolysis releasing aromatic amines and the TSNA adduct 4-hydroxy-1-(3-pyridyl)-1butanone (HPB), the extraction, cleanup, and concentration are performed by a one-step procedure using C 1 8 cartridges. Determination in the p...
متن کاملThe Biochemistry of Aromatic Amines
1. 2-Naphthylhydroxylamine and 2-nitrosonaphthalene were present in urine of dogs but not of guinea pigs, hamsters, rabbits or rats dosed with 2-naphthylamine. N-Acetyl-2-naphthylhydroxylamine and its O-sulphonic acid and O-glucosiduronic acid were not detected in the urine of any of these species. 2. Bile from rats dosed with 2-naphthylamine contained (2-naphthylamine N-glucosid)uronic acid an...
متن کاملSpectrophotometric determination of trace amount of some aromatic amines in pharmaceutical formulations, wastewater and biological fluids
A simple, accurate, sensitive and rapid method for the determination of some aromatic amines in either the pure form or in pharmaceutical formulation or in biological fluids or in waste water sample is proposed. The method is based on the formation of colored compounds with sodium 1,2-naphthoquinone-4-sulphonate and cetyltrimethyl ammonium bromide in alkaline medium. Beer’s law of colored speci...
