The reaction between aluminum and reagents causes a reddish tint in the sample. Description Ascorbic acid Aluminon reagent Bleaching powder Quantity 1 packet 1 packet 1 packet REQUIRED REAGENTS Code HI 93712A-0 HI 93712B-0 HI 93712C-0 REAGENT SETS HI 93712-01 Reagents for 100 tests HI 93712-03 Reagents for 300 tests For other accessories see page 49. MEASUREMENT PROCEDURE · Select the Aluminum method using the procedure described in the Method Selection section (see page 12). · Fill a graduated beaker with 50 mL of sample. · Add the content of one packet of HI 93712A-0 Ascorbic acid and mix until completely dissolved. · Add the content of one packet of HI 93712B-0 Aluminon reagent and mix until completely dissolved. This is the sample. 10 mL · Fill two cuvettes with 10 mL of sample each (up to the mark). 10 mL #2 #1 17 Aluminum · Add the content of one packet of HI 93712C-0 Bleaching powder to one of the two cuvettes. Replace the cap and shake vigorously until completely dissolved. This is the blank. #1 · Place the blank into the holder and close the lid. · Press Timer and the display will show the countdown prior to zeroing the blank. Alternatively wait for 15 minutes and then press Zero. The display will show "-0. 0-" when the meter is zeroed and ready for measurement. #1 #2 · Remove the blank and insert the other cuvette into the instrument. · Press the Read key and the meter will perform the reading. The instrument displays the results in mg/L of aluminum. · Press or to access the second level functions. · Press the Chem Frm key to convert the result in mg/L of Al2O3. · Press or to return to the measurement screen. INTERFERENCES Interference may be caused by: Iron above 20 mg/L, Alkalinity above 1000 mg/L, Phosphate above 50 mg/L; Fluoride must be absent. Aluminum 18 FREE CHLORINE SPECIFICATIONS Range Resolution Accuracy Typical EMC Deviation Light Source Method 0. 00 to 2. 50 mg/L 0. 01 mg/L ±0. 03 mg/L ±3% of reading at 25 °C ±0. 01 mg/L Tungsten lamp with narrow band interference filter @ 525 nm Adaptation of the EPA DPD method 330. 5. The reaction between free chlorine and the DPD reagent causes a pink tint in the sample.
