ملخص المقالة :
زمینه و هدف: ترکیبات فنلی یکی از مهم ترین مواد آلاینده هستند که موجب سمی شدن منابع آب می گردند. حضور فنل و مشتقات آن در آب و فاضلاب به دلیل سمیت و تهدیدی که برای زندگی انسان، حیوان و محیط ایجاد می کند یک نگرانی عمده محسوب می شود. به هر- حال شناخت و ردیابی این آلاینده ها و همچنین شناخت راه های کنترل و حذف آن ها امری بسیار مهم برای حفظ محیط زیست، تصفیه انواع فاضلاب و تأمین آب آشامیدنی سالم و بهداشتی می باشد. لذا این تحقیق با هدف اصلی حذف آلاینده فنل از محیط آبی با غلظت اولیه بالا(mg/l100) توسط فرایند هتروژن فوتوکاتالیست در راکتور با پوشش شیشه ای پیرکس با بستر شبه مایع انجام یافت.روش بررسی: ابتدا آنالیز پاسخ سطحی برای نانوکاتالیست TiO2 به همراه هیدروژن پراکسید و اشعه UV 250 وات، برای یافتن شرایط بهینه حذف فنل از محیط آبی به روش هتروژن فوتوکاتالیست انجام شد.سپس جاذب SBA-15 که به دلیل ساختار متخلخل قابلیت زیادی در حذف آلاینده فنل در میان سایر جاذب ها دارد و سپس نانوکامپوزیت TiO2/SBA-15 سنتز شد. سپس ویژگی های ساختاری و فیزیکی نانوکامپوزیت توسط آنالیزهایTEM ، FESEM، BET ، XRD شناسایی شد.یافته ها:نتایج بیان گر کارایی حذف 96% فنل با غلظت mg/l100 در مدت زمان 420 دقیقه بود.استفاده از روش پاسخ سطحی برای تعیین شرایط بهینه یکی از روش های مؤثر برای دست یابی به هدف مورد نظر در این تحقیق بود.بحث و نتیجه گیری: با توجه به نتایج، ملاحظه می شود که مواد مزو متخلخل پریودیک حاوی TiO2 در مقایسه با TiO2 پشتیبانی نشده راندمان بالایی در تخریب فوتوکاتالیزوری آلاینده های آبی دارد.
