Influence of Variety, Location, Growing Year, and Storage on the Total Phosphorus, Phytate-Phosphorus, and Phytate-Phosphorus to Total Phosphorus Ratio in Rice

Journal of Agricultural and Food Chemistry, 2010
The influence of variety, location, growing year, and storage on the total phosphorus (total P), phytate-P, and phytate-P to total P ratio in Korean rice varieties was investigated. Experiment 1 investigated the influence of 9 rice varieties, 4 locations, and 2 growing years.

Procedures for the storage and digestion of natural waters for the determination of filterable reactive phosphorus, total filterable phosphorus and total phosphorus

Analytica Chimica Acta, 1998
Abstract An overview of the forms of phosphorus species likely to be encountered in natural waters and the implications for the measurement of filterable and total phosphorus is given. Procedures reported in the literature for the storage and digestion of water samples for filterable reactive phosphorus (FRP), total filterable phosphorus (TFP) and ...

Determination of soluble phosphate, and total phosphorus in sea-water and of total phosphorus in marine muds

Mikrochimica Acta, 1956
The use ofp-methylaminophenol sulphate (metol) at 100‡ for the reduction of phosphomolybdic acid in the determination of phosphate in sea-water has a number of advantages over stannous chloride. The molybdenum blue colour once formed, is stable for several hours, and the calibration curve is not dependent upon the batches of reagent used; Beer's law is

Automated determination of total phosphorus in aqueous samples

Talanta, 1991
The determination of total phosphorus in an automated microbatch analyzer system is described. The procedure combines persulfate digestion of the sample and colorimetric detection of orthophosphate by the ascorbic acid reduction of phosphomolybdate in a single processing chamber.

Total phosphorus, phytate-phosphorus and phytase activity in plant feedstuffs

Animal Feed Science and Technology, 1994
Abstract A total of 285 samples representing 51 feedstuffs used in Belgian feed-mills were quantitatively analysed for phytase activity, phytate-P and total P. It was concluded that the number of feedstuffs showing significant phytase activity (more than 100 units kg−1) is rather limited (n = 13).

Determination of total dissolved phosphorus and particulate phosphorus in natural waters1

Limnology and Oceanography, 1980
Procedures are presented for separate analyses of total dissolved phosphorus and total particulate phosphorus in natural waters. The method for both procedures involves drying a sample with magnesium sulfate and baking the residue at a high temperature to decompose organic phosphorus compounds.
