ملخص المقالة :
زمینه و هدف : روی یک عنصر فراوان در پوسته زمین با مقدار تقریبی 04/0 گرم به کیلوگرم می باشد. روی در طبیعت بیش تر به صورت سولفید روی یافت می شود. همچنین جذب روی توسط ته نشست ها نیز مقدار روی محلول در محلول های آبی را کاهش می دهد. در این مطالعه، به بررسی حذف فلز روی توسط جلبک سندسموس پرداخته شد. روش بررسی : جهت تعیین میزان جذب فلز روی توسط جاذب سندسموس تحت شرایط مختلف غلظت آلاینده، دوز جاذب، زمان تماس، pH تماس داده و با دستگاه جذب اتمی مقدار باقی مانده اندازه گیری شد. ایزوترم های جذب و مدل سازی سینتیکی یون های فلزی بر روی جاذب بر اساس آزمون مدل های ایزوترم لانگمیر، فروندلیچ و سینتیک های شبه درجه اول و شبه درجه دوم تعیین شدند. یافته ها: جذب به وسیله مدل های ایزوترم لانگمویر و فروندلیچ و سینتیک جذب توسط مدل های شبه مرتبه اول و شبه مرتبه دوم شرح داده شدند. نتایج نشان داد ضریب همبستگی، سینتیک جذب از مدل شبه مرتبه دوم با مقدار برابر 1 و تعادل توسط ایزوترم فروندلیچ با مقدار 7926/0 توصیف شدند. بحث و نتیجه گیری: فرآیند جذب در این مطالعه نشان داد با توجه به ضریب همبستگی بالا جلبکScenedesmus spقابلیت خوبی در حذف فلز روی دارد و می تواند به عنوان پیشنهادی مناسب جهت حذف روی از پساب ها مورد استفاده قرار گیرد.
