چکیده مقاله :

زمینه و هدف: برگ نخل یکی از پسماندهای کشاورزی است که سالانه در حجم وسیعی در کشور تولید می شود. در این مطالعه قابلیت خاکستر برگ نخل به عنوان یک ماده جاذب ارزان قیمت جهت حذف یون‌های Cadmium (II) از محلول های آبی مورد بررسی قرار گرفت. روش بررسی: متغیرها شامل pH (7-2)، غلظت یون های فلزی در محلول (mg/l 350-50) و مقدار جاذب (g/l 14- 1/0) در سیستم جذب ناپیوسته بودند. یافته ها: pH بهینه برای حذف یون های Cd(II)، 4 به دست آمد. بررسی متغیر میزان جاذب در این مطالعه نشان داد که با افزایش مقدار جاذب از 1/0 تا g/l 11 میزان جذب افزایش و پس از آن تا g/l 14 که حد بالای متغیر مورد نظر است، تقریبا ثابت شود. هم چنین کارایی جذب در مدت 60 دقیقه در غلظت mg/l 100 بیش ترین مقدار بود. بحث و نتیجه گیری: با توجه به نتایج، در نهایت جذب بهینه در شرایط pH 4، میزان جاذب g/l 11 و غلظت یون های کادمیم mg/l100 برابر %36/92 به دست آمد.جمع بندی نتایج این مطالعه نشان داد که خاکستر برگ نخل دارای پتانسیل بسیار خوبی جهت حذف یون های سمی فلزات سنگین از قبیل کادمیم از محلول های آبی می باشد.

چکیده انگلیسی:

Background and Objective: Annually, large amount of date-palm leafs are produced as waste products of agriculture in Iran. In this study, the potential of date-palm leaf ashes as an inexpensive adsorbent for Cd(II) removal from aqueous solutions has been investigated. Method: The studied variables were pH (2-7), Cd (II) ion concentrations (50 – 350 mg/l) and adsorbent dose (0.1 – 14 g/l) in batch systems. Findings: The optimum pH for the removal of Cd (II) ions was equal to 4. Investigation of the effect of adsorbent dose showed that the removal efficiency increased with the increase of adsorbent dose from 0.1 to 11 g/l, and after that the removal efficiency was stabled with the increase of adsorbent dose. The highest removal efficiency was obtained at 60 minutes in 100 mg/l Cd(II) concentration. Discussion and Conclusion: According to results, optimum removal efficiency of Cd(II) in pH 4, adsorbent dose of 11 g/l and Cd(II) ions concentration of 100 mg/l was obtained as 92.36%. It was concluded that the date-palm leaf ash had a good potential as an adsorbent for the removal of toxic heavy metals, such as cadmium, from aqueous solutions.
