Without undue exposure to air, transfer 4 to 5 grams of ferric chloride to a tared weighing bottle, using a clean paper funnel to prevent ferric chloride from coming in contact with the grou
6、nd joint. Stopper the bottle immediately, and reweigh the bottle and contents. Wash the specimen into a 500 milliliter (mL) volumetric flask with water, cool to approximately 25 OC, and fill the bottle to the mark with water and shake by hand. Allow the contents to settle for about 10 minutes and th
7、en vacuum filter approximately 425 mL of the solution through a tared Gooch crucible, containing an acid-washed asbestos pad, into a dry vacuum flask. Remove the flask containing the filtrate and save the filtrate for succeeding analyses. Replace the vacuum flask with another vacuum flask and filter
8、 the remaining solution. Wash the flask with water and add washings to the Gooch crucible. Repeat the washing procedure six times, allowing the filter to pull dry between each washing. Wash the precipitate once with ethyl alcohol. Dry the crucible and precipitate for 30 minutes at 100 OC, heat for 1
9、5 minutes at 600 OC, cool in a desiccator to room temperature, and reweigh. All weighings shall be to the nearest milligram (mg). Calculate the percent water insolubles as follows: Percent water insolubles = 1 O0 A B Where A = Weight of precipitate (weight of crucible with asbestos pad and precipita
10、te minus weight crucible with asbestos pad), and B = Weight of sample (weight of weighing bottle and sample minus weight of weighing bottle). 2.1.2 Ferrous chloride (FeCl,). A sample of the filtrate from 2.1.1 shall have the percentage of ferrous chloride determined 6 accordance with the procedures
11、of the American Water Works Association (AWWA) Standard for Liquid Ferric Chloride, ANSUAWWA B407. 2.1.3 Ferric chloride (FeCl3. A sample of the filtrate from 2.1.1 shall have the percentage of total iron determined, and subsequently the percentage of ferric chloride calculated, when tested in accor
12、dance with the procedures of ANSUAWWA B407. 2.2 Impurities. The ferric chloride supplied shall be certified as suitable for contact with or treatment of drinking water in accordance with the requirements for impurities given in ANSI/AWWA B407. 3.
