چکیده

نانوجاذب­های پلیمری سیکلودکسترین (CDs)/ پلی اتر بلک آمید PEBA)) با توجه به ماهیتشان از جمله تخلخل پذیری، زیست سازگاری و زیست‌تخریب‌پذیری به‌عنوان نانوکامپوزیت­های پلیمری نوین از اهمیت کاربردی خاصی برخوردار می­باشند. هدف از این پژوهش بهینه­سازی حذف جلبک عامل طعم و بو در آب آشامیدنی با استفاده از نانوجاذب­های PEBA/CDs بود. طراحی آزمایش‌ها و تأثیر پارامترهای تجربی بر میزان حذف جلبک، به‌صورت سیستماتیک با روش Fractional Factorial انجام گرفت.  جهت دستیابی به بیش­ترین عملکرد حذف جلبک، از روش بهینه­سازی RSM استفاده شد. به‌منظور مشخصه­یابی این نانوساختارها از طیف‌سنجی FTIR، تصاویر SEM، فن BET و آنالیز نقشه‌برداری استفاده شد. این آنالیزها نشان دادند که محصولات سنتزی دارای خواص ایده­آلی همچون ریخت­شناسی همگن و توزیع اندازه الیاف در گستره نانومتری هستند. علاوه براین، بر اساس اطلاعات حاصل از آنالیز BET، سطح مؤثر نمونه در حدود m2/g 840 تعیین شد. نتایج بررسی­ها بر روی جلبک Navicula نشان داد که نانوجاذب­های پلیمری PEBA/CDs می­توانند با کاهش تعداد کلنی جلبک به 5 کلنی بر کیفیت‌بخشی طعم و بو در آب آشامیدنی تأثیرگذار باشد. نتایج آنالیز واریانس نشان داد که پارامترهای مقدار جاذب پلیمری، حجم آب و مدت‌زمان تماس به­دلیل داشتن Pvalue برابر با صفر بر میزان حذف جلبک تأثیرگذار هستند. همچنین یافته­ها نشان‌دهنده کاهش تعداد کلنی جلبک به میزان 3 کلنی بود. استفاده از نانوساختارهای نوین و همچنین مطالعه سیستماتیک به­کاررفته در این مطالعه می­توانند به‌عنوان یک راهبرد جدید به‌منظور کیفیت‌بخشی به آب آشامیدنی استفاده شود.

چکیده [English]

Cyclodextrin (CDs)/polyether black amide (PEBA) polymeric nanostructures are of particular practical importance due to their nature including porosity, biocompatibility and biodegradability as new polymeric nanocomposites. The aim of this research work was to optimize the odour and taste causing algae in drinking water using PEBA/CDs nanoadsorbents. The design of experiments and the effect of experimental parameters on the rate of algae removal was done systematically by Fractional Factorial method. RSM optimization method was used to achieve the highest algae removal performance. FTIR spectroscopy, SEM images, BET technique and mapping analysis were used to characterize these nanostructures. These analyzes showed that the nanoadsorbents synthesized had ideal properties such as homogeneous morphology and fiber size distribution in the nanometer range. In addition, according to data obtained from BET technique, the surface area of the sample was about 840 m2/g. The results of studies on Navicula algae showed that PEBA/CDs polymeric nanoadsorbents can affect the quality of drinking water by reducing the number of algae colonies to 5 colonies. The results of analysis of variance showed that the parameters of dose of polymeric nanoadsorbents, water volume and contact time (Pvalue = 0.000) affect the rate of algal removal. The results showed a reduction in the number of algae colonies by 3 colonies. The use of novel nanostructures as well as the systematic studies used in this study can be used as a new strategy to improve the quality of drinking water.
