Iron (total & soluble), CHEMets Visual Kit, CHEMetrics
Supplier: CHEMetrics
Ideal for low- to medium-range colorimetric analysis of water quality
CHEMets® test kits utilize self-filling ampules and vacuum pulls the sample up from a snap cup into the ampule when the tip is broken off. After tilting the ampule several times to mix the sample and reagent and waiting for the color to develop (usually 2 minutes or less), the analyst quantifies the result using the provided cylindrical comparator (for concentrations ≤1ppm) or flat comparator (for concentrations ≥1ppm).
The soluble iron content of surface waters rarely exceeds 1 mg/L, while ground waters often contain higher concentrations. The National Secondary Drinking Water Standard for iron is 0.3 mg/L, as iron concentrations in excess of 0.3 mg/L impart a foul taste and cause staining. High concentrations in surface waters can indicate the presence of industrial effluents or runoff.
Phenanthroline method: Ferrous iron reacts with 1,10-phenanthroline to form an orange-colored chelate. To determine total iron, thioglycolic acid solution is added to reduce ferric iron to the ferrous state. The reagent formulation minimizes interferences from various metals. Results are expressed as ppm (mg/L) Fe.
Delivery information: Soluble and total iron test kit K-6010 comes in a plastic case and contains everything needed to perform 30 tests: Refill, Low and High Range Comparators, Activator Solution, 25 mL sample cup, and instructions.
