| چکیده | ||
| در این کار، نانومزوپوز SBA-16 از ساقه گیاه نی به روش سبز تهیه شد و برای حذف آلاینده فنل فتالئین استفاده گردید. اثر پارامترهای مختلف (pH، غلظت اولیه فنل فتالئین، مقدار جاذب SBA-16، دما و زمان تماس) در میزان جذب فنل فتالئین توسط جاذب تهیه شده، به کمک نرم‌افزار طراحی آزمایش بررسی شد. نتایج حاصل از آزمایش‌های پیش‌بینی شده نشان داد که بالاترین جذب فنل فتالئین در شرایط 01/4=pH، دمای °C 44، زمان تماس min 20، غلظت اولیه جذب شونده mg/L 13 و مقدار جاذب g 05/0 دیده می‌شود. در شرایط بهینه، پیش‌بینی نرم‌افزار حذف 100 درصدی فنل فتالئین از محیط آبی بوده است که عملا میزان حذف 46/99 درصد به دست آمد. با توجه به پتانسیل بالای نانومزوپور SBA-16 در حذف رنگدانه فنل فتالئین، می‌تواند کاندیدای مناسبی در حذف آلاینده‌های رنگی و تصفیه فاضلاب‌های کارخانجات نساجی محسوب شود. | ||

| چکیده [English] | ||
| In this work, nanomesopose SBA-16 was prepared from reed plant stem by green method and used to remove Phenolphthalein pollutant. The effect of different parameters (pH, initial concentration of phenolphthalein, amount of SBA-16 adsorbent, temperature and contact time) on the amount of phenolphthalein absorption by the prepared adsorbent was investigated with the help of experiment design software. The results of the predicted experiments showed that the highest absorption of phenolphthalein was in the conditions of pH=4.01, temperature 44°C, contact time 20 min, initial concentration of adsorbent 13 mg/L and amount of adsorbent 0.05 g. can be seen. In optimal conditions, the prediction of the software was 100% removal of phenolphthalein from the water environment, which actually achieved a removal of 99.46%. Considering the high potential of nanomesopore SBA-16 in removing phenolphthalein pigment, it can be considered as a suitable candidate for removing colored pollutants and treating wastewater from textile factories. | ||
