چکیده

جذب سطحی یون فلز سرب (2+) از نمونه­های آبی به وسیله نانوکامپوزیت پلی اتر سولفون (PES)/نانولوله‌های کربنی (CNT) آمین‌دار‌شده با متغیرهای pH، سرعت همزن، زمان تماس، مقدار جاذب و غلظت اولیه یون فلزی بررسی شد. نتایج FTIR و EDX برای نمونه اصلاح‌شده نشان داد که گروه‌های آمینی نوع اول (N-H2) و نوع دوم (N-H) روی سطح CNT قرار گرفتند. همچنین عکس‌های SEM گویای تغییر ساختار CNT، شکسته شدن آن‌ها و به دنبال آن ایجاد نظم بیشتر بود. سرعت جذب یون به وسیله نمونه نانوکامپوزیت نشان داد که تعادل سینتیکی جذب در 10 دقیقه اول تماس رخ داده است. برای حذف بیشینه یون فلزی، مقادیر نانوجاذب برابر g 1/0 به ازای mL 100 نمونه آبی، pH محیط خنثی و غلظت اولیه یون ppm95 تعیین شد. همچنین مدل ایزوترم فرندلیچ و مدل سینتیکی شبه­ درجه‌دوم، بهترین همپوشانی را باداده­های آزمایشگاهی داشت.

چکیده [English]

Adsorption of lead metal ion [Pb(II)] from aqueous samples was investigated using polyethersulfone (PES)/amine-functionalized carbon nanotubes (NCNTs) via changes of pH, stirring speed, contact time, adsorbent content and initial metal ion concentration. The FTIR and EDX results for the modified sample showed that the first type amine groups (N-H2) and the second type amine groups (N-H) were located on the CNT surface. The SEM images also showed CNTs structure change, their breaking down followed by providing more order. The rate of ion adsorption by the nanocomposite sample showed that the kinetic equilibrium of adsorption occurred within the first 10 min of contact time. To maximize the metal ion removal, the amounts of nano-adsorbent, pH and initial ion concentration were determined 0.1 g/100 mL aqueous sample, 7, and 95 ppm, respectively. Also, the Freundlich isotherm model and the pseudo-second order kinetic model had the best correspondence with the experimental data.
