| چکیده | ||
| نانوذرات ZnO جاذبهای قوی برای جذب مواد آلی و غیرآلی میباشند. در این پژوهش نانوذرات ZnO با استفاده از کورکومین در دمای °C 160 و 10=pH سنتز شده و از آن برای حذف متیلن بلو با غلظت‌های اولیه مختلف، و در دما ها و pH ها ی متفاوت مورد استفاده قرار گرفت. ویژگیهای فیزیکی و مورفولوژی نانوذرات سنتز شده با استفاده از تکنیکهای XRD، DLS، SEM، FTIR و BET آنالیز گردید. نتایج نشان داد با افزایش دما، ابتدا مقدار جذب تا °C 40 افزایش و سپس کاهش یافت که بیشترین جذب برابر با mg/g 320 بود. با افزایش pH نیز مقدار جذب افزایش یافت و در محیط بازی (10=pH) مقدار جذب بیشینه و برابر با mg/g 235 به دست آمد. بررسـی سـینتیک جـذب سطحی دادهها نشان داد که سینتیک حذف رنگ از مدل سینتیکی شبه مرتبه دوم پیروی میکند. همچنـین نتـایج ایزوترم جذب نشان داد که نتایج حاصل از جذب با مدل ایزوترم جذب در حال تعادل لانگمویر تطابق خوبی نسبت به فروندلیچ دارند (99/0=R2 و 564/0= RL ). حداکثر ظرفیت جذب بر مبنای ایزوترم لانگمویر در مقدار mg/g 324 حاصل گردید. مقادیر به دست آمده از پارامترهای ترمودینامیکی نیز نشان داد که جـذب متیلن بلو گرماگیر و خودبخودی است. | ||

| چکیده [English] | ||
| ZnO nanoparticles (NPs) are effective adsorbents in removal of various organic and inorganic contaminants. In this study, ZnO NPs were synthesized using curcumin at 160 ° C and pH = 10 and used to degradation methylene blue at different initial concentrations and at different temperatures and pHs. Physical and morphological properties of the synthesized NPs were analyzed using XRD, DLS, SEM, FTIR and BET. Obtained results indicated that by increasing the temperature up to 40 °C, adsorption was initially increased to maximum amount of 320 mg/g and then decreased. Furthermore, maximum amount of adsorption was obtained by increasing in the pH (235 mg/g at pH=10). Results revealed that adsorption kinetics in order to dye remove was well fitted using a pseudo second-order kinetic model. The obtained results were also indicated that the Langmuir equation could be predicted the dye adsorption, better than the Freundlich equation, due to its higher R2 (0.99) and RL (0.564). According to the Langmuir equation, maximum adsorption capacity was 324 mg/g. The obtained values for the thermodynamic parameters were also indicated that the dye adsorption was an endothermic and spontaneous process. | ||
