Sampling

1. When preparing the sample, chlorine outgassing, e.g. through the pipette or

shaking, must be avoided.

2. The analysis must take place immediately after taking the sample.

Preparation

1. Cleaning of vials:

As many household cleaners (e.g. dishwasher detergent) contain reducing

substances, this can lead to lower results with the determination of chlorine.

To avoid measurement errors, the glassware used should be free of chlorine

consumption. To achieve this, all glassware should be placed in a sodium

hypochlorite solution (0.1 g/L) for one hour and then rinsed thoroughly with

deionised water.

2. For individual testing of free and total chlorine, the use of different sets of

glassware is recommended (EN ISO 7393-2, 5.3)

3. The DPD colour development is carried out at a pH value of 6.2 to 6.5. The

reagents therefore contain a buffer for the pH adjustment. Strong alkaline or acidic

water samples must therefore be adjusted between pH 6 and pH 7 before the

analysis (use 0.5 mol/Lsulphuric acid or 1 mol/Lsodium hydroxide).

Remarks

1. Evotablets can be used as an alternative to the corresponding standard tablet (e.g.

DPD No.3 Evoinstead of DPD No.3).

Interferences

Persistant Interferences

• All oxidising agents in the samples react like chlorine, which leads to higher results.

Removeable Interferences

• Interference from copper and iron (III) are eliminated by the addition of EDTA.

• The use of reagent tablets in samples with high calcium content* and/or

high conductivity* can lead to turbidity of the sample and therefore incorrect

measurements. In this case, the alternative reagent tablet DPD No.1 High Calcium

and reagent tablet DPD No.3 High Calcium should be used.

*it is not possible to give exact values, because the development of turbidity depends

on the composition and nature of the sample.

• Concentrations above 10 mg/L chlorine, in the event of using fluid reagents, can

lead to results within the measuring range of up to 0 mg/L. In the event of a high

concentration of chlorine, the sample must be diluted with chlorine-free water. 10

mLof the diluted sample should be mixed with the reagent and the measurement

taken again (plausibility test).

Iron LR (Fe2+ und Fe3+) Tablet / 250 515371BT

Preparation

1. Water that has been treated with organic compounds such as corrosion inhibitors,

must be oxidised where necessary to break down the iron complex. 1 ml of

concentrated Sulphuric acid(≥ 95 %) and 1 ml concentrated Nitric acid(≥ 65 %) is

therefore added to to 100 ml water sample and boiled down to approximately half

the volume. After cooling down, the digestion procedure is continued.

Remarks

1. This method is for the determination of total dissolved Fe2+ and Fe3+.

2. For the determination of Fe2+, the IRON (II) LR Tablet, instead of the IRON LR

Tablet is used.

Removeable Interferences

1. pH values below 6.5 and above 8.4 can produce results inside the measuring

range. A plausibility test (pH-meter) is recommended.

2. Salt error

For salt concentrations below 2 g/L, no significant error, is expected due to

the salt concentration of the reagent tablet. For higher salt concentrations the

Probenahme

1. Bei der Probenvorbereitung muss das Ausgasen von Chlor, z.B. durch Pipettieren

und Schütteln, vermieden werden.

2. Die Analyse muss unmittelbar nach der Probenahme erfolgen.

Vorbereitung

1. Reinigung der Küvetten:

Da viele Haushaltsreiniger (z.B. Geschirrspülmittel) reduzierende Stoffe enthalten,

kann es bei der Bestimmung von Chlor zu Minderbefunden kommen. Um diesen

Messfehler auszuschließen, sollten die Glasgeräte chlorzehrungsfrei sein. Dazu

werden die Glasgeräte für eine Stunde unter Natriumhypochloritlösung (0,1 g/L)

aufbewahrt und danach gründlich mit VE-Wasser (Vollentsalztes Wasser) gespült.

2. Für die Einzelbestimmung von freiem Chlor und Gesamtchlor ist es sinnvoll, jeweils

einen eigenen Satz Küvetten zu verwenden (siehe EN ISO 7393-2, Abs. 5.3).

3. Die DPD-Farbentwicklung erfolgt bei einem pH-Wert von 6,2 bis 6,5. Die

Reagenzien enthalten daher einen Puffer zur pH-Wert Einstellung. Stark alkalische

oder saure Wässer müssen jedoch vor der Analyse in einen pH-Bereich zwischen

6 und 7 gebracht werden (mit 0,5 mol/LSchwefelsäure bzw. 1 mol/LNatronlauge).

Anmerkungen

1. Evo-Tabletten können alternativ zu der entsprechenden Standard-Tablette

verwendet werden (z.B. DPD Nr. 3 Evo anstatt DPD Nr. 3).

Störungen

Permanente Störungen

• Alle in den Proben vorhandenen Oxidationsmittel reagieren wie Chlor, was zu

Mehrbefunden führt.

Ausschließbare Störungen

• Störungen durch Kupfer und Eisen(III) sind durch EDTA zu beseitigen.

• Bei Proben mit hohem Calciumgehalt* und/oder hoher Leitfähigkeit* kann es

bei der Verwendung der Reagenztabletten zu einer Eintrübung der Probe und

damit verbundener Fehlmessung kommen. In diesem Fall sind alternativ die

Reagenztablette DPD No. 1 High Calcium und die Reagenztablette DPD No. 3 High

Calcium zu verwenden.

*exakte Werte können nicht angegeben werden, da die Entstehung einer Trübung von

Art und Zusammensetzung des Probenwassers abhängt.

• Konzentrationen über 10 mg/L Chlor, bei Verwendung von Tabletten, können zu

Ergebnissen innerhalb des Messbereichs bis hin zu 0 mg/L führen. Bei einer zu hohen

Chlorkonzentration muss die Probe mit chlorfreiem Wasser verdünnt werden. 10
