Wantabe et al [88] have described a method for the separation and determination
of siloxanes in sediment, using inductively coupled plasma emission spectrometry.
A petroleum ether extract of the sediments is evaporated to dryness. The damp residue
is dissolved in methyl isobutyl ketone and aspirated into the plasma. The detection
limit is 0.01 mg kg
−1 . Recoveries are about 50% with a coefficient of variation of
about 11%.
Van der Post et al [89] has described a method for the determination of silanols
in water based on their ability to reduce nitrite or nitrate to ammonia at normal
temperature. Individual silanols were identified by mass spectrometry.
