HI-7214-25 Pool Line Reagents for Iron High Range - 25 tests
Specifications
| Range | 0.00 to 5.00 ppm (mg/L) |
| Resolution | 0.01 ppm (mg/L) |
| Precision | 2% of reading ±0.04 ppm (mg/L) @ 25°C |
| Method | Adaptation of EPA Phenanthroline method 315B, for natural and treated waters. The reaction between iron and reagent causes an orange tint in the sample. |
| PLEASE NOTE: | In some cases, samples may contain other parameters which may interfere with results |
| Interferences may be caused by: | Alkalinity: above 2,000 mg/L (as CaCO3). May slow down colour development (negative error). To resolve this, neutralise the sample with diluted HCl. Calcium (Ca2+): above 10,000 mg/L as CaCO3 Copper (Cu2+): does not interfere: reagent contains a masking agent. Magnesium (Mg2+): above 100,000 mg/L as CaCO3 Molybdate Molybdenum: above 25 mg/L (as Mo-MoO4) (positive error) Sample containing up to 50 mg/L Mo-MoO4 may be measured if a reading is taken after 1 minute instead of 3 minutes. High Iron concentrations up to 200 mg/L do not inhibit colour development; above 200 mg/L colour development may be inhibited. High sulphide concentrations (S2-): high sulphide concentrations may interfere. To reduce sulphide: acidify the sample and boil for about 20 minutes, neutralise and adjust volume before measurements. Silica (SiO2): above 175 mg/L (as SiO2). May slow down colour development (negative error) |
