Processes and systems for the purification of bio-organic compounds arc described. In certain embodiments, the purification method comprises adjusting the pH of the composition to a basic pH. In further embodiments, the purification method optionally comprises neutralizing the composition to reduce the ...
effectiveness is their suitability for separation, sizing and purification of a wide range of organic substances such as proteins, oligo- and polypeptides , enzymes, antibiotics, dyes, lipids, oils and in general non volatile organic compounds produced either by in vitro synthesis or biotechnologically...
Thus a separation of organic compounds from the nonionic surfactants in aqueous solution become possible, which is potential for cloud point extraction (CPE)... L Rui,Z Wang,JH Xu,... - 《Separation & Purification Technology》 被引量: 69发表: 2009年 Application of quantitative structure–proper...
Water purification encompasses the removal of pollutants such as industrial dyes, heavy-metal ions, microplastics, and organic matter from water as well as the collection of freshwater (e.g., through seawater desalination or atmospheric condensation).

When organic compounds are chemically transformed by a PCO device, it is the hydroxyl radical (OH), derived from the oxidation of adsorbed water or adsorbed OH−, that is the dominant strong oxidant. Its net reaction with a VOC can be expressed as:OH + VOC + O2→ nCO2 + mH2O The ...
Disclosed is a novel capping-and-tagging (“cap-tag”) strategy that aids in the purification of compounds assembled by multi-step synthetic methods. The incorporation of a unique cap-tag into undesired intermediates during a multi-step synthesis allows for the straightforward removal of...
The polymerization is usually effected in the presence of a catalyst, e.g. potassium hydroxide or fluorosulphonic acid. Specific oxides include ethylene, propylene and butylene oxides, oxacyclobutanes, tetrahydrofuran, 3-hydroxymethyl oxacyclobutane, glycidol and diepoxides. The organic compounds ...

Furthermore, organic compounds may also have multiple environmental transformation processes, causing more analysis difficulties. Compound-specific stable isotope analysis (CSIA) is an efficient method for source apportionment and identifying the transformation process of organic compounds. Usually, the ...
