چکیده

کلش گندم به عنوان یک پسماند کشاورزی کم ارزش حاصل از فرآیند برداشت و عمل­آوری گندم از مزارع شناخته می­‌شود که سرشار از سیلیس بی­شکل می‌­باشد که فرآیند استخراج آن ساده بوده و نیاز به مواد شیمیایی و تجهیزات پیچیده­ای ندارد و می‌­تواند به عنوان یک ماده اولیه ارزان قیمت و در دسترس جهت تولید مواد بر پایه سیلیس مورد استفاده قرار گیرد. در مطالعه حاضر، سیلیس بی­شکل و فعال از کلش گندم به روش شست ‌و شوی اسیدی با اسیدهای مختلف شامل HCl، HNO3، H2SO4 و H3PO4 با موفقیت استخراج گردید و از آن در سنتز نانوکامپوزیت Fe3O4@SiO2 استفاده شد. سپس، نانوکامپوزیت سنتز شده توسط گروه عاملی کیتوسان (CS) عامل‌دار شده تا بیونانوکامپوزیت Fe3O4@SiO2@CS به ‌دست آید. ویژگی‌­های ساختاری مواد تولید شده با استفاده از آنالیز­های XRF، XRD، FT–IR، VSM، BET، SEM و پتانسیل زتا مورد بررسی قرار گرفت. نتایج حاصل نشان داد، سیلیس بی­شکل و فعال با خلوص 52/96% با استفاده از شست‌ ‌و شوی اسیدی با HNO3 از کلش گندم استخراج شده است. همچنین، نتایج حاصل از آنالیز VSM خاصیت سوپر پارامغناطیسی بیونانوکامپوزیت Fe3O4@SiO2@CS را با خاصیت مغناطیسی emu g–1 17/55 نشان داد. به علاوه، نتایج حاصل از حذف رنگ نشان داد، میزان حذف رنگ بازیک قرمز 46 با استفاده از بیونانوکامپوزیت سنتز شده 97% بوده و ظرفیت جذب آن mg g–1 1700 می‌­باشد که در مقایسه با سایر جاذب­‌ها بسیار بالاتر و مطلوب­تر می‌­باشد. جداسازی بیونانوکامپوزیت سنتز شده از محلول­‌های رنگی با استفاده از یک آهنربای خارجی انجام شد.

چکیده [English]

In the present study, amorphous silica was successfully extracted from wheat straw by acid leaching technique using various acids including HCl, HNO3, H2SO4 and H3PO4 and was used in the synthesis of Fe3O4@SiO2 nanocomposite. Then, the synthesized nanocomposite were functionalized by chitosan functional group (CS) to obtain Fe3O4@SiO2@CS bionanocomposite. The percentages of the constituents, the crystallization state, the identification of the functional groups and the surface morphology of the produced materials were investigated using XRF, XRD, FT–IR, VSM, BET, SEM and zeta potential analyzes. Finally, the synthesized Fe3O4@SiO2@CS bionanocomposite was used for removal of Basic Red 46 dye from aqueous solutions as an efficient and effective adsorbent. The results showed that pure and active silica with purity of 96.52% was extracted from wheat straw using acid leaching with HNO3 acid. Also, the results of VSM analysis showed the superparamagnetic properties of Fe3O4@SiO2@CS bionanocomposite with magnetic properties of 17.55 emu g–1.In addition, the results of dye removal showed that the Basic Red 46 dye removal efficiency using synthesized Fe3O4@SiO2@CS bionanocomposite was 97% and adsorption capacity of it was 1700 mg g–1, which is much higher and desirable than many other adsorbents.
