Water quality. Physical, chemical and biochemical methods - Determination of phenol index: 4-aminoantipyrine (4-aminophenazone) spectrometric methods after distillation not-eligible — apparatus used to controlWhat is BS 6068 2. 12 Physical, chemical, and biochemical methods about? BS 6068 2. 12 specifies methods for determining the phenol index (3. 2) in waters, surface waters, and wastewaters. After a preliminary distillation, the test samples are analyzed according to the specific application as follows: Method A (direct colorimetric method): This method is capable of measuring the phenol index in test samples that contain more than 0,10 mg in the
