Determination of boiler water and cooling water and oil content
1 Scope
This standard specifies the method for determination of boiler water and cooling water and oil content.
The standard infrared spectrophotometry for boiler feed water, return water and chemical production equipment cooling water, the oil content of 0.1mg/L ~
Determination of 100mg/L, but also applies to other water samples Determination of oil content; UV spectrophotometry applied to thermal power plant boiler feedwater
Water, return water and chemical production equipment cooling water - Determination of oil content of 4.0mg 0.1mg/L ~/L of.

GB/T 6682 analytical laboratory use specifications and test methods (GB/T 6682-1992, neq ISO 3696. 1987)
3 infrared spectrophotometry
3.1 Principle
Methyl mineral oil, methine significant absorption at 3.41μm wavelength within a certain range of concentrations its absorption into the value of the oil content
Directly proportional. Law carbon tetrachloride extraction of oil in water samples, and then use an infrared spectrophotometric quantitative determination.
Under normal circumstances, applied to the determination of boiler feed water, production water returned no interference exists; the determination of circulating cooling water, an organic phosphine in a
Under general dose nor interfere with the determination.
Determination of criteria used oil may have the following two options.
① to hexadecane and iso-octane mixture of equal volumes of oil as standard, known standard mixture. In this case the measurement result should be multiplied by school
Positive factors 1.4.
② in the return water from the production or circulating cooling water extracted oil or oil composition to be measured close to mineral oil as standard oil.
3.2 Reagents and materials
The method of the reagents and water, unless otherwise specified, shall use analytical reagent and in line with GB/T 6682 three water requirements.
Safety Tips. The standard used carbon tetrachloride irritating, should pay attention to protection. When contacted, rinse with plenty of water, avoid
Avoid inhalation or contact with the skin.
