Abstract    Assessment of adsorption zinc (II) ions from aqueous solution using alginate-SBA-15 sorbent nanocomposite was investigated as a function of zinc concentration, solution pH, and contact time. For that purpose, the alginate-SBA-15 nanocomposite adsorbent was prepared through encapsulation method by immobilization mesoporous SBA-15 into a polymeric matrix. Identification of functional groups and surface morphology of the obtained nanocomposite was carried out by X-Ray diffraction (XRD), scanning electron microscopy (SEM), fourier transform infrared spectroscopy (FTIR) and nitrogen porosimetry experiments. Sorption performance of the alginate-SBA-15 adsorbent during batch experiments was studied. A mathematically explanation of adsorption process using kinetics and isotherm models was also performed. Kinetic study was revealed that the pseudo second-order model has good agreement with the experimental results than the pseudo first-order model. Therefore, it indicates that the concentration of both alginate-SBA-15 and zinc metal ions are involved in the rate determining step of the sorption process. The qmax value for zinc (II) ions adsorption onto alginate-SBA-15 was found 46.3 mg g-1. According to thermodynamic analysis, physisorption and the endothermic of the sorption process nature of Zn(II) ions onto alginate-SBA-15 nanocomposite was revealed.

چکیده    در مقاله حاضر، جذب یون روی از محلول آبی با استفاده از نانوکامپوزیت alginate-SBA-15، به عنوان تابعی از غلظت اولیه روی، pH محلول و زمان تماس بررسی شده است. بدین منظور، نانوکامپوزیت alginate-SBA-15 با روش کپسوله سازی به طریق تثبیت مزوپوروس SBA-15 درون یک ماتریکس پلیمری تهیه شده است. تعیین گروه های عاملی و مشخصه یابی سطح جاذب بدست آمده با استفاده از تکنیک های پراش پرتو ایکس (XRD)، میکروسکوپ الکترونی روبشی (SEM)، طیف سنجی مادون قرمز تبدیل فوریه (FT-IR) و تخلخل سنجی نیتروژن انجام شده است. عملکرد جذب جاذب alginate-SBA-15 طی آزمایشات ناپیوسته مطالعه شده است. به منظور توصیف ریاضیاتی فرآیند جذب، مدل های ریاضی سینتیکی و ایزوترم های تعادلی بر روی داده های آزمایش اعمال شده اند. مطالعه سینتیک نشان داد که مدل سینتیکی شبه درجه دوم تطابق بهتری با داده های تجربی نسبت به مدل شبه درجه اول دارد. بنابراین، آن نشان می دهد که هم غلظت یون های فلز روی و هم alginate-SBA-15در مرحله تعیین نرخ فرآیند جذب دخالت دارند. مقدار qmaxبرای جذب یون­های روی بر روی جاذبalginate-SBA-15برابر46.3 mg g-1بدست آمده است. طبق تحلیل ترمودینامیکی، ماهیت فیزیکی و گرماگیر بودن فرآیند جذب یون­های روی بر روی نانوکامپوزیت alginate-SBA-15 اثبات شد.
