    Methods Iron LR with Liquid reagent 0.03 – 2 mg/l Fe and Fe This test is suitable for determining total soluble iron. The sample should be pre-filtered using a 0.45 µm membrane if total dissolved iron is required. Particulate or suspended iron will otherwise add to the result.
  • Page 26 Methods Notes: 1. Complexed iron may be measured by increasing the development period until no further colour development is seen. Very strongly complexed iron may not be included in the measured iron. In this case the complexing agent must be destroyed by oxidation with acid/persulphate followed by neutralisation to pH 6–9.

  • Page 40 Methods Notes: 1. While the UV lamp is on UV safety goggles must be worn. 2. For handling of the UV lamp see manufacturer's manual. Do not touch the surface of the UV lamp. Fingerprints will etch the glass. Wipe the UV lamp with a soft and clean tissue between measurements. 3.

  • Page 41: Polyacrylate With Liquid Reagent

    Methods Polyacrylate with Liquid reagent POLY 1 – 30 mg/l Polyacrylate Fill a clean vial (24 mm Ø) with 10 ml of the water sample and 0.0.0 perform zero calibration (see “Operation”). Fill the vial with drops of the same size by holding the bottle vertically and squeeze slowly: 1 ml (25 drops) KS255 (Polyacrylate reagent 1) (note 1).
  • Page 42 Methods Notes: 1. If little or no turbidity is present at correct dose concentrations, the sample will need a pre-concentration step in order to detect this level of polyacrylate/polymer. Carry out this procedure as directed then test the pre-concentrated sample as above (see next page). 2.
  • Page 43 Methods Interference removal and Pre-Concentration Cartridge Preparation 1. Remove the plunger of the 20 ml syringe from the barrel and attach the C18 cartridge. 2. Add 5 ml of KS336 (Propan-2-ol) to the syringe barrel, attach the plunger and pass drop- wise through the cartridge.
  • Page 44 Methods Pre-Concentration Pre-concentration uses exactly the same procedure as interference removal, except a greater volume of sample is used in step 1, instead of deionised/tap water. For calculation of the original sample concentration a concentration factor should be considered: If a 50 ml sample is used the concentration factor is 20/50 = 0.4 If a 100 ml sample is used the concentration factor is 20/100 = 0.2 This can be extended as required in order to concentrate the polyacrylate/polymer suf- ficiently for analysis.
