Analysis for nitrates was performed by use of the cadmium reduction method 4500-NO3-E (APHA 1998), total reactive orthophosphates were analyzed following the U.
Water samples from the hypolimnion were analyzed for nitrates, orthophosphates, and ammonia following the procedures described above.
The soluble reactive phosphorus is a measure of orthophosphate
Dobson JW, Wells KL, Fisher CD (1970) Agronomic effectiveness of ammonium orthophosphate
and ammonium polyphosphate as measured by ion uptake and yield of corn.
Due to a great chemical similarity with the biological calcified tissues, many calcium orthophosphates
possess remarkable biocompatibility and bioactivity.
Topics include: the geochemical characteristics of rare earth elements in granitic laterites in Hainan Island, China; rare earth dodecaborides; controlled growth and property adjustment of vanadium oxide nanorods; the application of rare earth metal in bioinorganic chemistry, and Raman scattering in rare earth orthophosphates
The monoclinic, monazite structure, orthophosphates
show a higher degree of Pb incorporation than the tetragonal xenotime structure, orthophosphates
Thus, it is possible that all calcium orthophosphates
can be listed under glaserite type structures.
