TRIVALENT CHROMIUM PROCEDURE Subtract hexavalent chromium from total chromium. Record as ppm trivalent chromium. Trivalent Chromium = Total Chromium – Hexavalent Chromium Chromium–Hexavalent, Trivalent & Total 4/4 Smart2 TEST PROCEDURES 10.04

COD can be empirically related to the Biological Oxygen Demand (BOD) and organic carbon content of a specific source of water. This correlation must be determined experimentally for each source of water. APPLICATION: Domestic and industrial wastes. RANGE: 0–1500 mg/L COD METHOD: Dichromate in the presence of silver salts, at high temperature in a closed system, oxidizes most organic compounds to 95-100% of the theoretical amount. This process is called digestion. As dichromate oxidizes the organic compounds, a green complex is formed. The concentration of the green complex is measured at 605 nm SAMPLE HANDLING & PRESERVATION: and is directly proportional to the COD of the sample. Collect samples in glass and test as soon as possible. If samples must be stored, preservation is accomplished by the addition of concentrated H2SO4 to adjust the pH below 2. Samples with suspended solids should be homogenized in a blender (100 mL for 30 seconds) and then stirred gently with a magnetic stirrer. Smart2 TEST PROCEDURES 03.05 COD–Standard Range 1/4
