Determination of Total Nitrogen and Phosphorus in Wastewaters by Alkaline Persulfate Digestion Followed by IC
Introduction Excess use of nutrients over the last several decades has caused significant water quality and health issues on a global scale. In the U.S., the impact of nutrient pollution has been identified as one of the most widespread, costly, and challenging environmental problems in the 21st century.1 Nutrient pollution causes excess algae growth (i.e., algal blooms) over large bodies of wa...
متن کاملExtraction of soil organic phosphorus.
Organic phosphorus is an important component of soil biogeochemical cycles, but must be extracted from soil prior to analysis. Here we critically review the extraction of soil organic phosphorus, including procedures for quantification, speciation, and assessment of biological availability. Quantitative extraction conventionally requires strong acids and bases, which inevitably alter chemical s...
متن کاملQuantification of individual phosphorus forms in surface sediments of the Southern Caspian Sea - Iranian Coast: A sequential extraction procedure
Seventy Two sediments from four stations (Anzali, Tonekabon, Noshahr and Amirabad), located in Caspian Sea-Iranian coast were examined on the basis of P-fractionation in autumn and winter of 2013-2014. Several forms of the phosphorus in sediment were separated and extracted according to sequential extraction method. Then the extracted phosphorus in each fraction was determined by UV–Vis spectro...

متن کاملProcedures for the storage and digestion of natural waters for the determination of ®lterable reactive phosphorus, total ®lterable phosphorus and total phosphorus
An overview of the forms of phosphorus species likely to be encountered in natural waters and the implications for the measurement of ®lterable and total phosphorus is given. Procedures reported in the literature for the storage and digestion of water samples for ®lterable reactive phosphorus (FRP), total ®lterable phosphorus (TFP) and total phosphorus (TP) measurements are summarised and the a...
