ملخص المقالة :
در این کار تحقیقی حذف اسید قرمز 97 (AR97) به عنوان یک آلاینده مدل از صنایع نساجی با استفاده از نانوذرات NiO از محیط‌های آبی مورد مطالعه قرار گرفته است. در ابتدا اندازه و خلوص نانوذرات NiO بهترتیب با استفاده از تکنیکهای TEM و XRD مشخص گردید. در ادامه کارایی نانوذرات NiO برای جذب سطحی و حذف AR97 مورد مطالعه قرار گرفت. نتایج نشان داد که نانوذرات NiO جاذب موثری برای حذف AR97 از محیط‌های آبی میباشند. بررسی تاثیر پارامترهای عملیاتی نظیر دما، pH، مقدار جاذب و غلظت اولیه آلاینده (AR97) در کارایی جذب سطحی نانوذرات NiO مورد بررسی قرار گرفت. نتایج بهینه بدست آمده از بررسی این پارامترها (دما، pH، مقدار جاذب و غلظت اولیه AR97) به ترتیب عبارتند از C° 25، 2، g L-14 و mg L-1 10 میباشند.
