| Abstract: | This paper studies the use of interval to measure the water flow analysis method of hexavalent chromium, and GB / T 7467-1987 Determination of hexavalent chromium in the water quality of the two diphenyl carbonyl hydrazine spectrophotometer controlled trials with satisfactory results. The method is very tedious to go out pre-processing centrifuge work, method is simple and has greatly enhanced the efficiency of detection and shorten the time, also has a precision of better features. This method is applicable to determination of drinking water, surface water, domestic sewage and industrial waste water hexavalent chromium. |
