phosphorus forms of the surface sediment in the iranian coast of the southern caspian sea
Authors
abstract
sediments from the southern caspian sea, located in iranian coast were examined on the basis of p-fractionation (five forms of phosphorus) by a sequential extraction scheme. ninety-six surface sediment samples (for each season with triplicate) were collected from eight sampling transects in 10 and 100 m depths during summer and winter in 2010-2011. the result indicated that the most abundant forms of phosphorus were calcium bound phosphorus. relative abundance of other forms of phosphorus follow the order: organic-p>fe-p>al-p>absorbed-p. the loosely absorbed phosphorus represented

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...
