Box , Chabahar, Iran. A novel 1- naphthalene sulfonic acid 1-NS molecularly imprinted polymer MlP -coated stir bar for sorptive extraction of four naphthalene sulfonates NSs from seawater samples was prepared. The extraction conditions, including pH, the absorption and desorption times, stirring speed, amount of NaCl and temperature were optimized and the optimum conditions were established as: the absorption and desorption times were fixed respectively at 10 and 15 min, stirring speed was rpm, pH was adjusted to 4. The detection limits were within the range of 1. The RSDs was within The method is very suitable for the determination of naphthalene sulfonates NSs in seawater samples.

Benzene and Naphthalene Degrading Bacterial Communities in an Oil Sands Tailings Pond

Oil sands process-affected water OSPW , produced by surface-mining of oil sands in Canada, is alkaline and contains high concentrations of salts, metals, naphthenic acids, and polycyclic aromatic compounds PAHs. Residual hydrocarbon biodegradation occurs naturally, but little is known about the hydrocarbon-degrading microbial communities present in OSPW. In this study, aerobic oxidation of benzene and naphthalene in the surface layer of an oil sands tailings pond were measured.

Oxidative aromatic coupling of meso -substituted porphyrins bearing one electron-rich naphthalene unit has been studied in detail.

Naphthalene is an organic compound with formula C 10 H 8. It is the simplest polycyclic aromatic hydrocarbon , and is a white crystalline solid with a characteristic odor that is detectable at concentrations as low as 0. It is best known as the main ingredient of traditional mothballs.

Facile Synthesis of Propranolol and Novel Derivatives

 - Почему же вся переписка Северной Дакоты оказалась в твоем компьютере. - Я ведь тебе уже говорил! - взмолился Хейл, не обращая внимания на вой сирены.  - Я шпионил за Стратмором.

И я меньше всего хотел, чтобы кто-нибудь в севильском морге завладел ею. - И вы послали туда Дэвида Беккера? - Сьюзан все еще не могла прийти в.  - Он даже не служит у. Стратмор был поражен до глубины души. Никто никогда не позволял себе говорить с заместителем директора АНБ в таком тоне.
