| چکیده | ||
| برنج یکی از اقلام غذایی مهم است که پسماند کشاورزی حاصل از آن پوستۀ شلتوک است. بخش عمدۀ خاکستر پوستۀ شلتوک (87-98 درصد) از سیلیکا تشکیل شده است و به کار بردن آن به عنوان ماده اولیه سنتز سیلیکا، در مقایسه با روش‌های دیگر، باعث کاهش آلودگی محیط‌زیست و کاهش مصرف انرژی می‌شود. پوستۀ شلتوک به علت داشتن هزینۀ پایین برای تولید سیلیکا، از نظر اقتصادی با صرفه استسیلیکا با دارا بودن ویژگی‌های منحصر به‌فرد همچون سطح ویژه بالا و تخلخل یکنواخت به عنوان نانوحامل در نانوریزپوشانی ترکیبات زیست‌فعال غذایی و دارویی کاربرد دارد. در این پژوهش، با هدف سنتز نانوذرات متخلخل سیلیکا از پوستۀ شلتوک به روش تخریب حرارتی، متغیر دمای کلسینه شدن در سه سطح 400، 600 و 800 درجه سلسیوس و متغیر دمای گلیسرول در سه سطح 200، 225، 250 درجه سلسیوس در نظر گرفته شد. نمونه سیلیکای کلسینه شده در دمای 600 درجه سلسیوس و دمای گلیسرول 200 درجه سلسیوس که دارای درصد خلوص بالا (حاوی 94/07 درصد سیلیکا) و ساختار بیشکل بود (2θ =22)، به عنوان نمونه مناسب در نظر گرفته شد. از روش سطح پاسخ نیز برای تعیین نمونه بهینه استفاده گردید. اندازۀ ذرات با استفاده از روش پراکندگی نور دینامیکی (DLS)، 252 نانومتر تعیین شد و ناحیۀ سطح ویژۀ آن 51/653 متر مربع بر گرم بود. | ||

| چکیده [English] | ||
| Rice is one of the essential food items; the agricultural residue obtained from it is rice husk. Most of the rice husk ash (87-98%) is composed of silica. Application of rice husk as a raw material for the synthesis of silica, compared to other methods, reduces environmental pollution and energy consumption. It is also economically viable due to its low cost. Silica is used as a nanocarrier in the nanoencapsulation of bioactive and pharmaceutical compounds due to its unique properties, such as its high specific surface area and uniform porosity. For this purpose, mesoporous silica nanoparticles were synthesized from rice husk by heat degradation at three calcination temperatures of 400, 600, and 800°C and glycerol mixing temperatures of 200, 225, and 250°C. Calcined silica at 600°C and 200°C glycerol were considered the optimal samples. This sample had a high purity (containing 94.07% silica) and an amorphous structure (2θ=22). The response surface method (RSM) was used to determine the optimal sample. Moreover, its particle size was 252 nm, as determined by dynamic light scattering. In addition, its specific surface area was high (51.653 m2 g-1). | ||
