 德國MN硅測試劑931033/931233 |
| VISOCOLOR® ECO Silica |
| Colorimetric determination of silica |
 |
In acidic solution soluble silica or silicates react with ammonium molybdate to form yellow silicomolybdic acid, which is reduced to silico-molybdenum blue with a reducing agent. (Reaction principle analogous to DIN EN ISO 16264-H57)

| Data and ordering information |
| REF |
931 033 (931 233) |
| Type |
colorimetric test kit (refill pack) |
| Range |
0 · 0.2 · 0.4 · 0.6 · 1.0 · 1.5 · 2.0 ·
2.5 · 3.0 mg/l SiO2 |
| Sufficient for |
80 determinations |
| Shelf life |
at least 3 years |
| Sea water suitability |

| Detectable with PF-12 |
yes |
| |
|
Natural water contains silica in different amounts, depending on the geological conditions the water encounters during its course. The silica occurs partly as soluble silicate, partly colloidal as polysilicic acids. The silica content in water for medium and high pressure boilers may not exceed certain limits; in power plants therefore constant measurement of the silica content is required.
