Role of organic matter, clay, and iron contents in the sorption of oxytetracycline on river sediments

Background: Oxytetracycline (OTC) is a widely-used antibiotic; metabolism studies indicate only partial assimilation of it inside the body. Traditional wastewater treatment plants cannot remove OTC, and this results in the release of considerable amounts of the drug into aquatic environments. There is much concern over the role of residual antibiotics in the development of new generations of ba...

Toxicity of nonionic surfactants

Nonionic surfactants are amphilic chemicals that enhance desorption and bioavailability by increasing solubility and dispersion of poorly soluble hydrocarbons and oils. This study was conducted to determine the toxicity of commercial nonionic surfactants by using the Microtox Acute Toxicity test which is a rapid, simple test for toxicity. The test uses the luminescent bacterium V. fischeri as t...

Nonionic surfactants in paper electrophoresis.

i-i E1IE HAVE BEEN a number of reports iii the literature regarding the use of surface active agents in zone electrophoretic studies of 1)100(1 serum proteins and hpoprotems. Ardr (1) found that cationic detergents formed, with serum protenis, complexes that migrated like $-lipoproteins, while aiiionic detergents formed complexes that clectrophoretically resembled -1ipoproteins. More recently, ...

Monte Carlo Simulations of Model Nonionic Surfactants

The focus of this work is on aggregation and micellization in a lattice model for nonionic surfactants. Formation of micellar aggregates as a function of temperature and surfactant chemical potential was studied by histogram reweighting grand canonical Monte Carlo simulations. Two di erent sets of site-site interactions were utilized. The critical micellar concentration (CMC) was determined fro...

Evaluation of the Effect of Nonionic Surfactants and TBAC on Surface Tension of CO2 Gas Hydrate

Given that most of the gaseous constituents of industrial chimneys are usually carbon dioxide which is one of the most important greenhouse gases. It seems that the hydration process is one of the newest methods for the separation of this gas from gaseous mixtures. In the gas hydrate formation industry, in addition to disadvantages, there are some advantages such as gas separation, transmission...
