| titleOfInvention | A kind of preparations and applicatio of mercaptopropyl trimethoxysilane modification flax adsorbent |
| abstract | The invention discloses a kind of preparation method and application technology of mercaptopropyl trimethoxysilane modification flax adsorbent, feature is: cleaned by flax, cut short, pulverize after drying, after flax drying using treatment fluid A and treatment fluid B process to pulverize respectively, flax must be oxidized, in the reactor, add by following composition mass percent, N, dinethylformamide: 50 ~ 75%, oxidation flax: 10 ~ 30%; Be heated with stirring to 65 ~ 75 DEG C, slowly drip thionyl chloride: 12 ~ 25%, dropwise, temperature rises to 80 ~ 90 DEG C, and isothermal reaction 3 ~ 5h, is cooled to room temperature, add mercaptopropyl trimethoxysilane: 1.0 ~ 3.0%, each component sum is absolutely, and stirred at ambient temperature reaction 6 ~ 12h, filters, with N, after dinethylformamide washing, vacuum drying, obtains mercaptopropyl trimethoxysilane modification flax.This adsorbent has very high adsorption capacity to arsenic, excellent physical chemistry and mechanical performance, and power of regeneration is strong, Reusability often, the not only low but also environmental protection of cost. |
