Volatile matter

The process of coke making emits particulate matters, volatile organic compounds (VOCs), carbon monoxide, and other pollutants. The various sources of emissions include the following ... 

Among the chemicals regarded as air pollutants under the dehni-tion are carbon monoxide, oxides of nitrogen, sulfur dioxide, particulate matter, volatile organic compounds (VOCs), ozone, and lead.

Matter Volatile and Loss on Ignition. The content of matter volatile in a pigment is determined by drying a sample in an oven at 105 2°C. This normally gives a measure of the moisture content. For standards, see Table 1 ( Matter volatile ).

As expected, the factor M (maximal mass of matter volatilized) is significantly influenced by the moisture content of wood. The difference between anhydrous and wet wood samples is naturally explained by the quantity of water which has to be evaporated, contributing to an increase of the value of M for the symmetric logistic functions for wet wood samples (H37),... 

Universal burner performance criteria include the ability of the burner to achieve the specified maximum and minimum firing rate at the required conditions, flame dimensions, and emissions compliance (NO, CO, particulate matter, volatile organic compounds (VOC), and noise). Each industry has its own unique design... 

In addition to the USDA standards, The Named Vegetable Oil Standard from the Codex Alimentarius Committee on Fats and Oils (Codex Alimentarius, 2006) identifies quality characteristics that oils must meet for international trade. For example, the standard states that an oil should be characteristic of the designated product and be free of foreign and rancid odor and taste. Maximum levels of matter volatile at 105°C (ISO 662 1998) (ISO, 2005) should be 0.2% m/m, insoluble purities (ISO 663 1998) (ISO, 2005) 0.05% m/m, and 0.005% m/m soap content [AOCS Cel7-95 (97)] (AOCS, 2005). Limits for metals are 1.5 mg/kg iron (Fe) in refined oils, whereas only 0.1 mg/kg of copper (Cu) is allowed in refined oils. For methods to measure Fe and Cu, use ISO 8294 1994 (ISO, 2005) or AOCS Ca 18b-91 (97) (AOCS, 2005). Limits for oil deterioration include peroxide value and acid value. Codex allows up to 10 meq/kg oil for refined oils. Acid value limits range from a low of 0.6 mg/KOH/g oil for refined oils.

Determination of matter volatile at 105°C According to the lUPAC (1964) method (lUPAC Standard Methods for the Analysis of Oils, Fats and Soaps, 5th edition, 1966 II.C.1.1 Moisture and Volatile Matter). Results are expressed as percentage of mass per mass. 

The matter volatile at 105°C in oil sample is usually determined according to I.S.I. procedure (I.S.I. 1984). The test sample is heated atl05°C until moisture and volatile matter were completely removed and the loss in mass was recorded. The result was expressed in percentage by mass.
