چکیده

یکی از روشهایی که برای جداسازی فلزهای سنگین از زیستگاه‌های آبی استفاده می‌شود، جذب زیستی است. هدف این پژوهش، ارزیابی پیامد هوموسی شدن و توانایی ریزجانداران کاه ‌گندم در جذب و نگهداری سرب از محیط‌های آبی بود. برای دستیابی به این هدف، کاه گندم در دمای آزمایشگاه و رطوبت 70 درصد برای هوموسی شدن نگهداری شد و در هر یک از روزهای 1، 20 و 60 ، نمونه‌هایی از آن برداشت شد و برخی از ویژگی‌های فیزیکی، شیمیایی و بیولوژیکی آن‌ها بررسی شد. سپس دو زیر نمونه سترون و ناسترون از آن آماده شد و همدماهای جذب سرب بر هر یک از مانده‌های نمونه‌برداری شده سترون و ناسترون با کاربرد غلظت‌های گوناگونی از سرب در محلول 001/0 نرمال نیترات سدیم در pH برابر 6 بررسی شد. از میان همدماهای جذب لانگمیر، فروندلیچ و تمکین تنها مدل تمکین بر دادههای جذب سرب خوب برازش نشد. بیشترین گنجایش جذب سرب 36/63 و 41/108 میلی‌گرم بر گرم به‌ترتیب در نمونه کاه گندم تازه- سترون شده و کاه گندم هوموسی شده ناسترون براورد شد. درصد جذب سرب در بالاترین غلظت به‌کار رفته آن در نمونه‌های ناسترون کاه گندم در روزهای انکوباسیون 1، 20 و 60 به‌ترتیب برابر 21/32، 43 و 96/60 درصد بود. با پیشرفت هوموسی شدن کاه گندم ضریب‌های Kl ، n و Kf نیز افزایش یافت. همه فراسنجه‌های جذب سرب در کاه گندم ناسترون به اندازه چشمگیری بیشتر از نمونه‌های سترون شده بود و این نشان می‌دهد که ریزجانداران کاه توانایی بالایی در جذب سرب از محیط آبی دارند.

چکیده [English]

Biosorption is one of the methods used for the separation of heavy metals from aquatic environments. The objective of this study was to investigate wheat straw humification and the capability of its microorganisms for the biosorption of Pb from aqueous solutions. Wheat straw (3 solution (0.001 N) with different Pb concentrations at pH 6. Among the Langmuir, Freundlich, and Temkine models, only the latter failed to fit Pb adsorption data. The highest sorption capacities (qmax) were obtained by the Langmuir model for the humified and unsterile sample (108.41 mg g1) and the lowest was obtained for the fresh and sterile sample (63.36 mg g1). Lead adsorption increased significantly with incubation time and its highest values were recorded with unsterile straw samples taken on days 1, 20, and 60 which were equal to 32.21, 43, and 60.96%, respectively, for the highest Pb concentration. The Langmuir constant (Kl) and Freundlich constants (Kf and n) were significantly higher for the more humified wheat straw samples compared to those for raw straw. All the adsorption parameters recorded higher values with the unsterile wheat straw compared to the sterile one, indicating the ability of the microorganisms to adsorb Pb from aqueous solutions.
