Chapter 1 : Introduction

1.1 Introduction

Chloromat 9184 TFC/pH version is an industrial analyzer for on-line selective measurement offree chlorine (HOCl + ClO ) in the field of drinking water treatment plants, distribution networks-

and any other application that requires free chlorine follow-up in the range of ppb and ppm.Measurement is done by an amperometric cell after the molecules diffused through amembrane.

1.2 About chlorine

Specific terms exist to mention the different species of chlorine :

- Active chlorine HOCl (hypochlorous acid)It is the most powerful disinfectant, up to 100 times more efficient than hypochlorite (seehereunder)

- Total Free Chlorine (TFC) : HOCl + ClO :-

It is composed of gaseous chlorine (at low pH values), hypochlorous acid HOCl andhypochlorite ion ClO . These species coexist, their relative proportion depending on pH and-

temperature (see curve below for a 25°C temperature).

- Total combinated chlorine (TCC) :It results from the addition of free chlorine plus chloramines (mono-, di- and trichloramine).

Fraction of Cl , HOCl and ClO react as a function of pH : :2-

CHLOROMAT 9184

The dissociation reactions are as follow :

Cl + H O ÷ H + Cl + HOCl pK1 = 4.6 at 25°C2 2+ -

HOCl ÷H + ClO pK2 = 7.5 at 25°C+ -

It is also important to notice that the dissociation constants are temperature-dependent.

1.3 Measuring principles

Active chlorine measure lies on the Clark cell principle.The sensor - amperometric type - is composed of :

- one gold working electrode where the main reaction occurs,- one silver counter-electrode which is also used as a reference electrode,- a potassium chloride-based electrolyte,- one microporous membrane selective to HOCl :

1 : Electrode 6 : Membrane holder

2 : Electrolyte 7 : Membrane

3 : Probe body 8 : Cathode

4 : Filling-in hole 9 :Membrane/sample interface

5 : Anode 10 : Sample

The HOCl molecules contained in the sample diffuse through the membrane. HOCl is then

CHLOROMAT 9184

1-3

located in a thin electrolyte layer, between the membrane and the cathode.A constant working potential is applied to the working electrode (cathode) where HOCl isreduced :

HOCl + H + 2e ÷ Cl + H O+ - -2

At the silver electrode (anode), silver is oxidised into Ag ions which then precipitate with the+

chloride ions :

2Cl + 2Ag ÷ 2AgCl + 2e- -

HOCl reduction at the cathode generates a current directly proportional to itsconcentration.

The electrochemical reaction and the diffusion through the membrane depend on temperature.The measuring cell is therefore equipped with a temperature sensor which enables to operatean automatic compensation of the measurement.

7.3 electrode rejuvenation procedure

After some months of operation (3 to 12 depending on sample chlorine concentration, adark AgCl coating may cover part of the silver anode.

This coating does not affect the measurement until 90% of the surface is contaminated.

When changing the electrolyte and the membrane, visually check the silver anode.If more than 2/3 of the surface is covered then an electrode rejuvenation following the procedure :

- soak the anode in 10% ammonia solution for about 1 hour, then rinse it with demineralisedwater and wipe it with a soft cloth.

Anode rejuvenation can also be done with light abrasive. In this case, the anode must bewashed in order to avoid silver or abrasive particles to remain in the electrolyte.
