What is simple distillation useful for? Boiling Point: The boiling point of a substance is defined as the temperature at which the vapor pressure of a liquid is equal to the vapor pressure of the surroundings. In simple terms, it is usually referred to as the temperature at which a liquid...
Petroleum, also called crude oil, is a naturally occurring liquid found beneath the earth’s surface that can be refined into fuel. A fossil fuel, petroleum is created by the decomposition of organic matter over time and used as fuel to power vehicles, heating units, and machines, and can ...
Since the nitrosamines arerelatively polar organic compounds, a liquid-liquid extraction was employed for fat-rich food samples. Acetone-water (3 : 1) or acetone-acetonitrile mixture satisfied the terms. What do nitrites in urine mean? Normal urine contains chemicals called nitrates. If bacteria en...
In most cases, the substance to be extracted, which may be a solid, a liquid or a gas, is dissolved in a liquid, along with other substances, and a liquid solvent is used for the extraction — this is sometimes called liquid-liquid extraction. The technique may also be applied to ...

Crude oil is a naturally occurring liquid petroleum product composed of hydrocarbon deposits and other organic materials formed from the remains of animals and plants that lived millions of years ago. These organisms were covered by layers of sand, silt, and rock, subject to heat and pressure, ...
As a kind of novel and efficient material, ionic liquids (ILs) are used for capture of acidic gases including SO2 and CO2 from flue gas. Due to very low content of acidic gases in flue gas, it is important to find functional ILs to absorb the acidic gases. However, up to now, there...
From drug development and DNA sequencing to high throughput PCR testing, automated liquid handling has revolutionised the way modern laboratories operate. Click to read more...
Many authors have demonstrated the interest of a-liquid scintillation with pulse shape discrimination for the measurement of a emitters like actinides in environmental samples. Nevertheless, this technique suffers from a lack of resolution. Indeed, the energy resolution is about 300 keV at 5-MeV alp...
The role of the liquid—liquid interface in extraction mechanisms of metal ions is briefly reviewed for chelate extraction, ion-association extraction, and synergistic extraction systems. Recent studies employing the high-speed stirring method uncovered the principal factors governing the role of ...
