| titleOfInvention | Preparation method of nylon membrane for adsorbing heavy metals |
| abstract | The invention provides a preparation method of a modified nylon membrane for adsorbing heavy metals, which comprises the steps of acidifying a nylon membrane, adding an activating agent for activation, reacting the activated nylon membrane with a diethylenetriamine solution, washing to be neutral after the reaction is finished, and drying to obtain the modified nylon membrane. The invention takes a nylon 66 membrane as a raw material, hydrochloric acid and N, N' -carbonyldiimidazole-anhydrous methanol solution as hydrolysis and activating agents, and a cross-linking agent of diethylenetriamine, and the membrane material for absorbing heavy metal, which is used for treating Cu, is obtained by synthesis 2+ 、Cd 2+ And Pb 2+ The adsorption amount of (a) is remarkably higher than that of the unmodified original membrane. In Cu 2+ 、Cd 2+ And Pb 2+ For Cu in mixed binary mixed solution adsorption experiment 2+ And Pb 2+ Has high adsorption capacity and selective adsorption, and good reusability and regeneration performance. |
