TREATMENT OF SPILLED CRUDE OIL IN ENVIRONMENT USING ENVIRONMENTALLY FRIENDLY NONIONIC TWEEN SURFACTANTS

Microemulsions with Nonionic Surfactants and Mint Oil

A combination of electrical conductivity, dynamic viscosity, dynamic light scattering and small angle X-ray scattering methods was used to study the properties of the water + propylene glycol/mixed nonionic surfactants/ peppermint oil + ethanol U-type microemulsions which can be diluted with any amount of water. The surfactants were sucrose laurate and ethoxylated mono-di-glyceride. The mixing ...

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...

با توجه به تحریم های بین المملی علیه صنعت بیمه ایران امکان استفاده از بازارهای بین المملی بیمه ای برای نفتکش های ایرانی وجود ندارد. از طرفی از آنجایی که یکی از نوآوری های اخیر استفاده از بازارهای مالی به منظور ریسک های فاجعه آمیز می باشد. از اینرو در این پایان نامه سعی شده است با استفاده از این نوآوری ها با طراحی اوراق اختیارات راهی نو جهت بیمه گردن نفت کش های ایرانی ارائه نمود. از آنجایی که بر...

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, ...
