Determination of the phosphate ion (and the silicate ion) via a new system for irradiation (k) today indium aluminide - link (emitter and photosensor) mediated by Continuous intravenous injection

Abstract

This work presents a new mode in on-line semiautomated determination of
orthophosphate and silicate ions through absorbance measurement for blue
Molybdenum(V)-Silicate-Ascorbic acid at 660nm. The method was used successfully as a
linear calibration graph for orthophosphate ion and silicate was in the range 0.01-2 ng.ml-1
and 0.3-2.5mg.ml-1 successively while 600 pg and 12 ng detected as a limit of detection.
Both ions were determent in tap water using standard addition method and found to be 30
and 9.2 μg.ml-1 for both ions successively.
