The ISO Draft International Standard (DIS) cited below has been published for Public Comment. Comments are due with BSI by 12 April. If anyone would like a copy please contact me.

A Committee Draft (CD) was circulated for comment in may 2009.

If approved, this International Standard is likely to replace BS 8855-2:2000 Soil Analysis – Method for the determination of coal tar-derived phenolic compounds.

Please note that there is a prescribed format for comments. These should be sent to: [log in to unmask].

ISO DIS 11709 Soil quality — Determination of selected coal-tar derived phenolic compounds using high performance liquid chromatography (HPLC)

1 Scope

This International Standard describes a method for the quantitative determination of selected coal-tar derived phenols, namely phenol, methyl phenols as (ortho-, meta-, para-)cresols, and dihydroxy benzenes as catechol, resorcinol, and hydrochinone in soil by using high performance liquid chromatography with ultraviolet (HPLC-UV-DAD) or fluorescence (HPLC-FLD) or electrochemical detection (HPLC-ELCD). It is applicable to all types of soil with contamination levels of individual phenols in the range of approximately 0,02 mg/kg to 10 mg/kg soil.

NOTE With this method also other higher methylated phenols, e. g. dimethylphenols as (2,3-; 2,4-; 2,5-; 2,6-; 3,4- and 3,5-)xylenoles; 2-isopropylphenol, 2,3,5-trimethylphenol and 1-naphthol can be analyzed provided the suitability and the validity of the method is proven.
