Study on the green decontamination method of riot dyeing agent rhodamine B

The riot dyeing agent Rhodamine B is a loaded in ammunition, which can produce serious environmental pollution after use. In order to eliminate the of rhodamine B, decontamination method with simple operation, wide material sources and green environment protection was studied. First, an orthogonal experiment used obtain concentration ratio decontaminant excellent performance, that is, best effect when hydrogen peroxide 15%, boric acid 3.5% ferrous sulfate heptahydrate 0.4%. Then, actual formulated decontaminants on examined by test tube immersion method. results experiments showed according optimal had significant effects both powder non-woven masks contaminated B. This has good application value be for ammunition sites clothes hazards
