3 Method summary
Paper, cardboard diisopropylnaphthalene solvent extraction method of extraction, gas chromatography - mass spectrometry, with diethyl-naphthalene as an internal standard
Calculations.
NOTE. diisopropylnaphthalene may be pulp, paper and paperboard contaminants. When the current use of recycled fibers will inevitably appear diisopropylnaphthalene. Diisopropyl
Naphthalene may be adsorbed on the surface or in the form of parcels. Acetone is fully effective solvent to extract the two forms of diisopropyl naphthalene.
4 Reagents and materials
Unless otherwise indicated, all reagents were of analytical grade, water GB/T 6682 stipulated level.
4.1 acetone.
4.2 Standard.
4.2.1 diisopropylnaphthalene (mixture of isomers) by the purity of diisopropylnaphthalene provided by the manufacturer.
