文档介绍：METHOD 5050
BOMB PREPARATION METHOD FOR SOLID WASTE
SCOPE AND APPLICATION
This method describes the sample preparation steps necessary to
determine total chlorine in solid waste and virgin and used oils, fuels and
related materials, including: crankcase, hydraulic, diesel, lubricating and fuel
oils, and kerosene by bomb oxidation and titration or ion chromatography.
Depending on the analytical finish chosen, other halogens (bromine and fluorine)
and other elements (sulfur and nitrogen) may also be determined.
The applicable range of this method varies depending on the
analytical finish chosen. In general, levels as low as 500 µg/g chlorine in the
original oil sample can be determined. The upper range can be extended to
percentage levels by dilution of bustate.
This standard may involve hazardous materials, operations, and
equipment. This standard does not purport to address all of the safety problems
associated with its use. It is the responsibility of the user of this standard
to establish appropriate safety and health practices and determine the
applicability of regulatory limitations prior to use. Specific safety statements
are given in Section .
SUMMARY OF METHOD
The sample is oxidized bustion in a bomb containing oxygen
under pressure. The liberated pounds are absorbed in a sodium
carbonate/sodium bicarbonate solution.
