Determination of phosphate levels in the southern part of Al-Hammar marsh water by flow injection analysis

Abstract

Flow Injection Analysis (FIA) was applied to determine phosphate concentration in water of the southern part of Al-Hammar marsh water from July 2007 to July 2008. A linear line was obtained over the range 0.25- 1.75 μg/ml of phosphate with regression coefficient for seven points is 0.9999. The detection limit was 0.075 μg/ml with % R.S.D for ten replicate analysis of 1.0 μg/ml phosphate is 0.511% and the dispersion coefficient in the flow system is 5.4. The samples can be analyzed at rates exceeding 72 sample per hour .It was noted that phosphate concentration ranged 0.295 - 1.450 μg/ml, whereas the maximum phosphate concentration was recorded in spring 2008 and the minimum in autumn 2008.

“…These organic pollutants are harmful. Even in relatively small numbers, they can cause major health dangers when released into rivers, endangering aquatic life and wildlife in addition to humans [3]- [6].…”

“…Due to metals nanoparticles' unique physical, chemical, and biological properties, such as their high thermal and electrical conductivity, chemical stability, and high catalytic activity as well as their biometrically relevant antibacterial and anticancer actions [6], [7], Their applications are noteworthy and unique. The majority of metal nanoparticles are created utilizing a range of chemical and physical processes, many of which use potentially poisonous and damaging reactive chemicals [8].…”
