Direct azo dyes and their effect on self-purification of water
Direct azo dyes and their effect on self-purification of water. Timofeeva, S. S.; Kashina, N. F.; Shevernovskaya, O. A. (Irk. Gos. Univ., Irkutsk, USSR). Deposited Doc., VINITI 6831-83, 109 pp. Avail. VINITI (Russian) 1983. DOCUMENT TYPE: Report CA Section: 61 (Water) Section cross-reference(s): 41 All azo dyes studied, i.e., Direct Fast Bordeaux [94362-47-7], Direst Fast Orange 2 Zh [39363-31-0], Direct Dark Green [3626-28-6], Nigrosine Water Sol. (I) [8005-03-6], Direct Fast Brilliant Blue [6527-70-4], Direct Violet S [38493-85-5], Direct Brown KKh (II) [2429-82-5], Direct Black Z [1937-37-7], Direct Black 4K (III) [2429-83-6], and Direct Diazo Black S, [2429-73-4] had no substantial effect on the O conditions, pH, the development of saprophites, and the total count of microorganisms in the water when present in concns. of 0.001 mg/L. At higher concns., e.g., 0.1, 1.0, and 5.0 mg/L, the dyes cause more significant changes in water quality indexes and impact water self purifn. The max permissible concns. that do not effect self purifn. processes are 0.01 mg/L for I, II, and III, and 0.001 mg/L for the rest of the dyes.
Determination of benzidine in direct dyes by a thin-layer chromatographic method
Determination of benzidine in direct dyes by a thin-layer chromatographic method. Genin, V. A.; Dvoskin, S. I.; Chertov, V. A. (Onkol. Nauchn. Tsentr., Moscow, USSR). Gig. Sanit., (8), 87-8 (Russian) 1977. CODEN: GISAAA. DOCUMENT TYPE: Journal CA Section: 40 (Dyes, Fluorescent Whitening Agents, and Photosensitizers) Section cross-reference(s): 59, 80 Benzidine [92-87-5] residues in direct azo dyes can be detd. by extn. of a 25-40 g dye sample with 200 mL CHCl3 with a Soxhlet extractor (45-70 cycles), concn. of the ext. to 10 mL, and thin-layer chromatog. with 9:1 CHCl3-EtOH as mobile phase. By this method 3 samples of Direct Bordeaux [1937-35-5] and 2 samples of Direct Brown KKh [2429-82-5] contained 17-35 and 38 mg/kg benzidine residues, resp. No benzidine was detected in 7 samples of Direct Black 3 [1937-37-7], although 0.001% deliberately introduced was easily detected.
