The balance of the total volatile acids (TVA) is important when studying anaerobic reactors, because high concentrations of TVA may affect the biochemical process and eventually disturb the anaerobic digestion, which may lead the reactor to the collapse.
Concentration of phenols in laboratory phenolic water samples, obtained by washing model samples of shale oil and gasoline fraction, varied from 1 to 8 g/L, that of volatile acids and bases in total is below 90 mg/L in the water from shale oil washing and below 160 mg/L in the water from gasoline fraction washing.
The Wine Titrino package contains a comprehensive application file with clearly-laid-out and detailed method descriptions, with parameters and titration curve examples as well as examples about the determination of: pH value, total titratable acidity, free sulfurous acid, total sulfurous acid, volatile acids, fixed acidity, ascorbic acid (vitamin C), reducing sugars, carbon dioxide, ash and ash alkalinity, calcium and magnesium, chloride, total phosphorus, sulfate, Na, NH4, K, F, alcohol.
Their volatile acid stills are second to none, and are not only highly accurate and valuable lab equipment, but also an amazing work of art.
During the drying of fermented cocoa beans, there is loss of volatile acids and water from the beans when this process occurs slowly, resulting in an increase in pH of the cotyledons [21].
The lab also measures fecal coliform, total solids, total suspended solids, volatile acids, CBOD and total phosphorus on a daily basis for the Water Pollution Control Division, which comprises the wastewater treatment and industrial pretreatment plants.
Conching reduces the moistness of the cocoa mass and removes the volatile acids.
The methodology consisted in accompanying a series of solids concentrations (total solids, TS; total volatile solids, TVS; and total fixed solids, TFS) in samples containing cheese whey and volatile acids used to simulate anaerobic reactor effluents.
When books start to decompose, they emit a complex mixture of organic compounds, including volatile acids, which then further contribute to their degradation," said a university spokeswoman.
It appears that the British analysts still consider the amount of volatile acids in butter as a criterion of the genuineness of the butter, declaring the butter is to be considered as adulterated if the figure indicating the amount of volatile acids is lower than one quite arbitrarily chosen.
Now on the market are adhesives containing no volatile acids or flammable monomers.
