Silicic acid regeneration from estuarine sediment cores*

silicic acid from particulate silica suspended in the water column has been shown by itself to be inade- quate to account for the observed summer increases in silicic acid concentrations (van Bennekom et al 1974) Such increases must also result from regeneration of silicic acid

Notes

is a dehydration reaction not an acid-base reaction in consequence di-silicic acid cannot easily be obtained from mono- silicic acid Di- silicic acid was in fact synthesized by hydrogenation of its hexa-benzoyloxy- derivative R 3 -SiOSi-R 3 R=CH 3 C 6 H 4 O Cyclic trisilicic acid Si 3 O 3 (OH) 6 and cyclic tetrasilicic acid Si 4 O 4 (OH) 8 were synthesized by variations of this method
