Description
Description
Hach reagent kit 2678500.
Parameter: Silicon Dioxide (Ultra Low Range)
Range: 3 - 1000 μg / L SiO2
Applications: For the determination of trace amounts of soluble silica (silicon dioxide) in pure and ultrapure water.
Method Description: A number of changes are required to adapt the low range silica method for trace level analysis in the ultra low range method. The use of a 1-inchPour-Thru Cell and liquid reagents is absolutely essential. Pour-Thru Cell increases the reproducibility of the optics and reduces the instability of readings that results from moving sample bottles. Liquid reagents provide more reproducible readings and a lower chance of blanks by eliminating the slight haze that can remain with powdered reagents.
The silica and phosphate in the sample react with molybdate ions under acidic conditions to form yellow silicomolybdic acid complexes and phosphomolybdic acid complexes. The addition of citric acid destroys phosphate complexes. The amino acid reagent F is then added to change the yellow silicomolybdic acid color to an intense blue that is proportional to the concentration of silica. The measurement wavelength is 815 nm for spectrophotometers (for the DR 1900 spectrophotometer: 800 nm).
