| titleOfInvention | Preparation of sephadex solid-supported brominated 1-propyl-3 methylimidazole adsorbent |
| abstract | The invention discloses a preparation method for a sephadex solid-supported brominated 1-propyl-3 methylimidazole adsorbent. The preparation method is characterized by comprising the following steps: performing sulfhydrylation on activated sephadex by mercaptoacetic acid; then adding the following components in percentage by mass into a reactor: 55-65 percent of acetonitrile, 5-12 percent of brominated 1-propyl-3 methylimidazole, 28-38 percent of sulfydryl sephadex, 0.5-2 percent of azodiisobutyronitrile to obtain a mixture, wherein all the component percentage sum is 100 percent; keeping the temperature of 70-80 DEG C, stirring, reacting for 25-28 hours, performing cooling and suction filtration, washing the mixture by deionized water until the filtrate is neutral, washing the filtrate by a small amount of ethyl alcohol, and drying the filtrate in a vacuum drying box with the temperature of 50 DEG C to obtain the sephadex solid-supported brominated 1-propyl-3 methylimidazole adsorbent. The adsorbent is extremely high in adsorption capacity to arsenic and chromium, high in physical and chemical stability, high in mechanical performance, high in regeneration capacity, low in cost and environmentally friendly, and the number of repeated use times is large. |
