Phosphate Ion Concentration In Boiler Water

Determination of phosphate concentration in boile

Abstract The impossibility of unambiguously estimating phosphate concentration by measuring boiler-water conductivity in a high-pressure drum boiler ( p b = 13.8 MPa) is shown. Mathematical models of ion equilibria in boiler water, which allow one to determine the concentration of phosphates and other ion admixtures from the measurement data obtained with the use of standard (conductormeters

Method for oxygen scavenging and scale preventio

1990-5-23 · Since there is a constant relation between the phosphate ion concentration in the boiler water and the amount of oxygen removed from the water, the phosphate ion concentration may be controlled in accordance with the amount of the dissolved oxygen in the boiler feed water and a sufficient oxygen-removing effect can therefore be obtained constantly.

2017-1-5 · The concentration of phosphate in seawater is too low to measure directly. For this reason, you will concentrate the phosphate (in each of two samples of filtered sea water as explained below) by precipitating it and re-dissolving it in a smaller volume. After chemical treatment, each solution should develop a pleasing blue color. You will measure
