چکیده

آلودگی فلزات سنگین خصوصا فلزات سنگین همراه با نفت از معضلات عمده زیست محیطی به شمار می‌روند. این آلاینده‌ها خاک، آب و اکوسیستم­های مرتبط را درگیر ساخته و مشکلاتی را برای فلور و حتی انسان‌ها ایجاد می‌کنند. با توجه به پتانسیل‌های بالقوه ریز جلبک‌ها در زمینه حذف و کاهش انواع آلودگی­ها اعم از نفتی و غیر نفتی (فلزات سنگین)، این پژوهش با استفاده از ریزجلبک Calothrix.sp جدا شده از مناطق آلوده نفتی با هدف بررسی کاهش فلز سنگین نیکل شکل گرفت که طی آن برخی رفتارهای فیزیولوژیک ریزجلبک نیز مطالعه گردید. طراحی آزمایشات با کمک نرم افزار Design expert و با در نظر گرفتن فاکتورهای 9-4 pH ، غلظت 5 تا 100 میلی­گرم بر لیتر نیکل در زمان 30 تا 120 دقیقه اجرا شد. نتایج نشان داد در 8pH  با میزان 74/80  میلی­گرم بر لیتر  نیکل و زمان 24/48 دقیقه بیشترین میزان جذب نیکل (69 درصد) بود. نتایج این تحقیق نشان داد تیماردهی بیومس با عوامل شیمیایی و فیزیکی مختلف در قالب­های مختلفی نظیر تثبیت و یا استفاده از متابولیت‌های آن، روند جذب را تسریع و تسهیل نموده و پتانسیل استفاده از این ریزجلبک را در سیستم‌های پالایش بعدی هموار می­نماید.

چکیده [English]

Pollution with heavy metals, especially those combined with petroleum, is one of the major environmental problems. These pollutants contaminate soil, water, and related ecosystems and cause problems for the flora and even humans. Considering the potential of microalgae for elimination of petroleum pollution and reduction of various heavy metals contaminations, this study was carried out using Calothrix sp., isolated from polluted areas with the aim of investigating the reduction of nickel as well as studying some physiological behaviors of microalgae. Experiments were designed using the Design Expert software and factors such as PH (pH4-9), nickel concentration (5-100 mg/L), and time (30-120 min) were considered. Results showed that at pH 8, 80.74 mg/L nickel concentration, and 48.24 min the highest nickel uptake (69%) was observed. Treatment of algal biomass with different chemical and physical factors in various forms, such as immobilization or use of its metabolites could improve and facilitate the absorption process and paves the way for the potential application of these microalgae in subsequent purification systems.
