چکیده مقاله :
چکیده 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. یافته‌ها: 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 نتیجه‌گیری: 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.
Background and Objective: Annually large amount of date-palm leafs are produced as waste products of agriculture are produced 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 usedwas investigated.Method: The studied vvariables were as 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. IExperiments for investigate of the effect of adsorbent dose showed that the removal efficiency increased with the increasing increase of adsorbent dose from 0.1 to 11g/l the removal efficiency increased and after thatafter that the, removal efficiency was stabled with the increasing increase of adsorbent dose, removal efficiency was stabled. The removal efficiency reached the highest value at 60 minutes in 100 mg/l Cd(II) concentration was highest value.Discussion and Conclusion: According to the results, optimum conditions for desirable Cd(II) removal efficiency of 92.36% was obtained Cd(II) in pH 4, adsorbent dose of 11g/l and Cd(II) ions concentration of 100 mg/l. was obtained 92.36%. This study concluded indicated that, date-palm leaf ashes, have a good potential, as an adsorbent, to remove the toxic heavy metals like including cadmium from aqueous solutions.Keywords: Pollution, Ash, Adsorption, Cadmium
