Phosphate sorption by jurassic oolitic limestones

1975-4-1  Phosphate appears to be bonded less strongly (k" ~ 0.05 m/#g P) on the low-energy adsorption sites of limestone LM 70 than on comparable sites (k" = 0.08--0.45 ml/~g P) on calcium carbonate present in soils derived from Jurassic limestones (unpublished data).

Adsorption and desorption of phosphate on

2010-7-1  The total mass of PO 4 3 input to the limestone in the first phase of the experiments was 1676 μmoles (Table 1). The amount of PO 4 3 desorbed from the limestone ranged from 3 to 25 μmoles upon flushing with blank DIW. The limestone retained 1235 μmoles of PO 4 3 or about 75% of the input PO 4 3 during phase I. 3.2.

Phosphate Mining, Kentucky Geological Survey,

Phosphate minerals occur in most members of the Lexington Limestone, principally the Tanglewood, Millersburg, and Grier Limestone, and parts of the Lexington which were mined in the early 1900's. Although commonly called collophane, the phosphates are

the high-tatric Albian condensed limestones (Tatra Mts). Their origin is due to accretional growth and intraformational reworking. They were slowly growing by accretion of colloidal phosphates, in form of a homogeneus mass with some microglobuies (supposedly phosphate-enriched microorganisms), and
