5), it is necessary to neutralize the sample by the addition of NaHCO3 until completion of effervescing of CO3 2À of the sample; otherwise, sharp color change of the water sample near the end point cannot obtained. 46 Characterization and treatment of textile wastewater Reagents i. Potassium chromate: dissolve 50 g K2CrO4 in a little distilled water. Add AgNO3 solution until a definite red precipitate is formed. Let it stand for 12 h, filter, dilute to 1 L. ii. 79 g AgNO3 and dilute up to 1 L with distilled water.

8. xii. 0 g 4-aminoantipyrine in distilled water and dilute to 100 mL. Prepare this solution daily. xiii. 0 g K3Fe(CN)6 in water and dilute up to 100 mL using distilled water. Filter if necessary, and store in a brown glass bottle. Characterization of Textile Wastewater 49 Actual process 1. Distillation A. 0 with H3PO4 solution using methyl orange as an indicator. Add 5 mL CuSO4 solution. Transfer to distillation flask and collect 500 mL distillate using measuring cylinder as receiver. If the distillate is turbid, repeat the same procedure as above.

9) Fortunately, this interference can be eliminated by the addition of HgSO4 to the sample prior to the addition of other reagents. The Hg2+ ion combines with ClÀ ions to form poorly ionized HgCl2 complex: Hg2 + + 2ClÀ ! 10) In the presence of excess Hg2+ ions, the ClÀ ion is so small that it is not oxidized to any extent. NO2À ions are oxidized to NO3À, and this interference can be overcome by the addition of sulfamic acid to the dichromate solution. Apparatuses a. Reflux assembly with water condensers b.
