Methods of test for petroleum and its products -- Determination of the manganese content of gasoline. Atomic absorption spectrometry (AAS) method

BSI BS 2000-455:2011

This standard1) specifies a method for the determination of the manganese content of automotive gasoline, when the manganese is present as methylcyclopentadienyl manganese tricarbonyl (MMT ®)2). The precision of this test method only applies to the determination of manganese in the range of 10 mg/L to 40 mg/L, but higher concentrations can be measured by prior dilution of the gasoline sample with the specified solvent to bring the test portion within the specified range of the method. The test method may not be applicable to gasoline containing highly cracked components (less than 18% (V/V) olefins as determined by ASTM D1319 non depentanized). Solutions of MMT® in gasoline are chemically unstable when exposed to light, and low and erratic results are expected if the gasoline is exposed to light prior to stabilization during analysis.

NOTE 1 For the purposes of this standard, the terms “% (m/m)? and “% (V/V)? are used to represent the mass fraction and the volume fraction respectively.

WARNING. This part of BS 2000 calls for the use of substances and/or procedures that can be injurious to health if adequate precautions are not taken. It refers only to technical suitability and does not absolve the user from legal obligations relating to health and safety at any stage.
