چکیده

در این پژوهش، جاذب نانوالیاف نایلون۶/نانوذرات کیتوسان (CS/N6NFs) با ترکیب روش های الکتروریسی و الکترواسپری ساخته شد. ابتدا بستر نانولیفی نایلون۶ به روش الکتروریسی ساخته شده و در ادامه الکترواسپری نانوذرات کیتوسان روی این بستر جهت ساخت جاذب انجام شد. جاذب ساخته شده با فنون، میکروسکوپی الکترون روبشی گسیل میدانی (FESEM)، زاویه تماس و آزمون کشش مورد بررسی قرار گرفت. مطالعات FESEM، نشان داد که نانوذرات کیتوسان بطور یکنواخت بر روی سطح نانوالیاف الکتروریسی شده نایلون۶ توزیع شده و به خوبی به الیاف متصل شده اند .تولید نانوذرات کیتوسان به روش الکترواسپری با توزیع اندازه ذرات تقریبا یکنواخت و با میانگین اندازه حدود nm 110 را نشان داد. نقش کیتوسان در بهبود میزان ترشوندگی با کاهش زاویه تماس از 06/64 به 80/53 مشاهده شد. مقادیر مدول یانگ به ترتیب برای N6NFs و Cs/N6NFs برابر 82/4 و MPa 28/5 بدست آمد. عملکرد جاذب Cs/N6NFs در حذف رنگزای اسید رد ۸ (AR8) از محلول های آبی بررسی شد. آزمایشهای نشان داد که مقدار g 015/0 از جاذب Cs/N6NFs توانایی حذف بیش از 95٪ از AR8 را دارد. آزمایشهای جذب در حالت ناپیوسته حاکی از آن است که جاذب طراحی شده برای جذبAR8 پس از 5 مرتبه احیا توسط NaOH، همچنان بازده جذب بالای 70% را دارد. ظرفیت جذب جاذب برای این رنگزا mg.g-1 16/195 محاسبه شد. مدل لانگمویر برازش مطلوبی با داده های تجربی ایزوترم جذب داشت. مطالعات سینتیکی نشان داد که داده های جذب از مدل شبه درجه دوم پیروی می کنند.

چکیده [English]

In this research, nylon 6 nanofiber/chitosan nanoparticles (CS/N6NFs) adsorbent was fabricated by combining electrospinning and electrospraying methods. First, the nylon 6 nanofibrous substrate was made by electrospinning method, and then chitosan nanoparticles were electrosprayed on this substrate to make a adsorbent. The adsorbent was characterized by, field emission scanning electron microscopy (FESEM), contact angle and tensile test. FESEM studies showed that chitosan nanoparticles are uniformly distributed on the surface of nylon 6 electrospun nanofibers and are well connected to the fibers. The production of chitosan nanoparticles by electrospraying showed an almost uniform particle size distribution with an average size of about 110 nm. The role of chitosan in improving wettability was observed by reducing the contact angle from 64.06 to 53.80. Young's modulus values were obtained for N6NFs and Cs/N6NFs equal to 4.82 and 5.28 MPa, respectively. The performance of Cs/N6NFs adsorbent in removing acid red 8 (AR8) dye from aqueous solutions was investigated. Experiments showed that the value of 0.015 g of Cs/N6NFs adsorbent has the ability to remove more than 95% of AR8. Adsorption tests in batch mode indicate that the adsorbent designed to absorb AR8 after 5 times of reduction by NaOH still has a high absorption efficiency of 70%. The adsorption capacity of the adsorbent was calculated to be 195.16 mg.g-1 for AR8. The Langmuir model had a good fit with the experimental data of the adsorption isotherm. Kinetic studies showed that the adsorption data followed a pseudo-quadratic model.
