The phrase "available phosphate" is correct and usable in written English.
It can be used in contexts related to chemistry, agriculture, or environmental science, typically referring to the form of phosphate that is accessible for use by plants or organisms.
Example: "The soil test revealed that there is a sufficient amount of available phosphate for optimal plant growth this season."
Alternatives: "accessible phosphate" or "readily available phosphate".
Slag forms a coarse aggregate used in certain concretes; it is used as a road material and ballast and as a source of available phosphate fertilizer.
Phosphate present in dissolved form was determined as available phosphate, and the sample was acid-digested for extraction of TP.
The percent removal of TP was slightly higher than the removal of available phosphate (AP) (Table 1).
Currently available phosphate binders are associated with either hypercalcemia or high costs, which limit their use in hemodialysis patients.
Fig. 2 Percent removal (curve represents normalized removal) of total phosphate (a), and available phosphate (b) from wastewater in Canna-based constructed wetland.
Average removal was 167 mg/m2 day for total phosphate and 84 mg/m2 day for available phosphate for an initial loading rate of 200 mg/m2 day and 85 mg/m2 day, respectively, at a HRT of 24 h.
These may then bind with readily available phosphates, carbonates or citrates, and form insoluble molecules.
However, the authors also found a second feedback mechanism involving soil nutrients, with invasive Pinus enhancing the levels of nitrate-nitrogen and available phosphate-phosphorus.
More recently, the efficacy of a commercially available phosphate-containing solution in preventing hypophosphatemia has been reported in patients undergoing CVVHDF [ 30] or CVVH [ 31].
This study evaluated the possibility to prevent hypophosphatemia during CRRT treatment by using a new commercially available phosphate-containing dialysis fluid.
In particular, we aimed at minimizing CRRT-induced phosphate depletion [ 42] through the combination of the citrate solution with a recently introduced, commercially available, phosphate-containing CRRT solution, acting as dialysate and post-dilution replacement fluid.
