VISOCOLOR® ECO Iron: Colorimetric determination of iron. Features: • Triazine method: iron(II) ions react with a triazine derivative to form a violet complex. • Iron(III) ions are reduced and thus also determined. • Natural waters as well as waste waters often contain some iron. • It can be present as Fe(II) or Fe(III) ions if the pH value of the water is below 3 or if the water is free of oxygen. • At higher pH values Fe(III) forms an insoluble oxyhydrate. • Frequently the sample is in a transition state with finely dispersed iron oxides. • In waste water and natural water containing humic acids iron is often present in the form of a complex salt. • The VISOCOLOR® test kits only determine iron which is present in dissolved form as Fe2+ or Fe3+ ions. • Iron complexes are not covered unless they are decomposed by oxidation with nitric acid and sulphuric acid. Specifications: • Type: colorimetric test kit • Range: 0 · 0.04 · 0.07 · 0.10 · 0.15 · 0.20 · 0.30 ·0.50 · 1.0 mg/l Fe • Sufficient for: 100 determinations • Shelf life at least: 2 years • Sea water suitability: yes • Detectable with PF-12: yes

VISOCOLOR® ECO Hardness (total): Titrimetric determination of total hardness. Features: • Complexometric titration in accordance with DIN 38406 E3 and DIN 38409 H6. • Copper(II) ions can delay or (in higher concentrations) even block the colour change of the indicator. • For this reason allow enough water to run through copper pipes prior to sampling. • The total hardness of water is based on its content of alkaline earth ions (calcium and magnesium ions). • This content depends on the geological conditions the water encounters during its course and may vary widely. • Knowledge of the total hardness is important for the use of water in industrial as well as municipal applications, e. g. in the household as wash water or as boiler feed water in industry. Technische Daten: Type: titrimetric test kit Range: 1 drop = 1 °d Sufficient for: 110 tests with an average hardness of 10 °d Shelf life at least: 1.5 years Sea water suitability: yes, after dilution (1+29) Detectable with PF-12: no

VISOCOLOR® ECO Potassium Features: • Determination of potassium as turbidity measurement • Potassium reacts with sodium tetraphenylborate to form a precipitate. • Under defined conditions this turbidity can be used for concentration measurements. • Turbidities interfere and have to be filtered prior to the test. • Good reproducibility is obtained for drinking, surface and ground water. • For polluted waste waters low potassium values are measured. • The natural potassium content in ground water is generally about 1 – 2 mg/l K+. • Higher values may indicate faecal contaminations, but can also originate from potassium fertilisers. • For the growth of plants and animals potassium is an essential factor. • Especially in agriculture the determination of potassium therefore gains increasing importance. Specifications: • Type: turbidity test kit • Range: 2 · 3 · 4 · 6 · 8 · 10 · 15 mg/l K+ • Sufficient for: 60 determinations • Shelf life at least: 3 years • Sea water suitability: yes, after dilution (1+1) • Detectable with PF-12: yes

• Description

VISOCOLOR® ECO pH 4.0 - 9.0 • Colorimetric determination of pH-value • A special mixture of indicator dyes assumes a characteristic colour for every pH value within the range of the kit. • The favourable ratio between sample volume and amount of indicator minimises the indicator error (acid-base-error). • This allows reliable pH measurements in weakly buffered solutions as well. • High contents of neutral salts and colloids as well as organic solvent concentrations above 10 % can cause wrong results. Type: colorimetric test kit Range: pH 4.0 – 9.0 Sufficient for: 450 determinations Shelf life at least: 3 years Sea water suitability: yes Detectable with PF-12: no • The pH value indicates whether a water reacts acidic, alkaline or neutral.• It is determined by the concentration of hydrogen ions. • All biological processes in water are tied to specific pH ranges. • For municipal and industrial applications, too, the control of specific pH limits is important since e. g. the efficiency of sewage plants or the corrosive action of tap water on the pipes depend in the pH value. • Contrary to pH indicator papers VISOCOLOR® pH test kits can also be used to determine accurate pH values in unbuffered sample solutions.
