Polarography with Organic Solvents

Recent Trends in Organic Polarography

INTRODUCTION The present paper does not attempt to be exhaustive in listing all of the current trends in the polarography of organic compounds. Rather, an attempt has been made to focus attention on those trends, which seem of major importance for future studies in organic polarography, with particular reference to some of the unsolved problems which still confront us. Significant recent activi...

Surface-directed channels filled with organic solvents.

Although channels of microfluidic devices are normally pipes, some groups have recently studied surface-directed channels. These channels were created between two stacked glass slides that were physically flat but chemically patterned. The working fluids used for such channels were mostly water solutions, though organic solvents are important in some applications such as organic synthesis. In t...

Preparation of coal slurry with organic solvents.

In this study, various organic solvents were used to prepare coal slurries and the rheological and thermal properties of coal-organic solvent slurries were examined. Solvents with molecules containing unpaired electrons (high basicity) show high extraction power and cause swelling of coal. Therefore, coal-organic solvent slurries usually showed higher viscosities compared to coal-water slurry. ...

Application of Oscillographic Polarography to Determinationof Organic Phosphorus Pesticide Residues

DNA extraction with organic solvents in gel barrier tubes.

The extraction of nucleic acids with phenol and chloroform is the standard method to remove proteins and lipids from cellular digests. A major drawback to the use of these organic solvents is their caustic and toxic qualities. Phenol can cause severe burns while chloroform is hepatotoxic and carcinogenic. We describe in this paper the use of a special blood collection tube to isolate the offens...
