| 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 the nylon membrane, activating the nylon membrane with an activating agent, reacting the nylon membrane with a diethylenetriamine solution, washing the nylon membrane to be neutral after the reaction is finished, and drying the nylon membrane to obtain the modified nylon membrane. The method increases the active sites on the surface of the membrane by hydrolysis and activation, and improves the heavy metal adsorption capacity of the membrane. The modified nylon membrane for adsorbing heavy metals, which is prepared by the method, comprises Cu 2+ 、Cd 2+ And Pb 2+ To Cu 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. |
