[ 3 ] - بررسی استفاده از کاه و کلش در حذف آلودگی نفتی از آب

هیدروکربن‌های آلی به دلیل سرطان‌زا و جهش‌زا بودن، نگرانی‌های زیادی را به وجود می‌آورند. در این پژوهش، از جاذب کاه و کلش به‌عنوان جاذب آلی برای حذف آلودگی نفتی از پساب استفاده­شد. آزمایش‌های جذب به‌صورت ناپیوسته با استفاده از محلول‌های آزمایشگاهی حاوی نفت انجام­گرفت. شرایط بهینه جذب با تغییر فاکتورهای مؤثر بر جذب که شامل pH، غلظت اولیه آلوده‌کننده، زمان تماس و مقدار جاذب بر میزان جذب که در سطوح ...

[ 4 ] - Population dynamics of Carasobarbus luteus in Shadegan International Wetland, Iran

Estimation of length at maturation and spawning time and determination of fishing prohibition time and optimum length for catch are of important information about a fish species. Seasonal samplings were conducted over a year to study population dynamic of Carasobarbus luteus in Shadegan wetland. Samples were collected from five sampling stations in Shadegan wetland (Salmane, Rogabe, Khoroosi, M...

[ 5 ] - Evaluation of effects of physico-chemical factors on chlorophyll-a in Shadegan International Wetland-Khouzestan Province - Iran

Measurement of chlorophyll-a can be considered important to investigate the primary production of an ecosystem. This study aimed to investigate chlorophyll-a concentration, primary production and the factors affecting them in Shadegan Wetland located in Khouzestan Province - Iran. Sampling for measuring (NO3, PO4, BOD5, DO, pH, EC, salinity, temperature) was performed seasonally at five samplin...

[ 6 ] - امکان سنجی تولید زیست توده و حذف فسفات و نیترات از پساب شهری به وسیله کشت جلبک کلرلا وولگاریس(Chlorella vulgaris )

مواد مغذی نیترات و فسفات به وفور در پساب­های شهری وجود دارد. برای ارزیابی کارایی جلبک سبز کلرلا وولگاریس در حذف نیترات و فسفات از پساب شهری و همچنین کاربرد آن به عنوان یک محیط کشت مناسب برای جلبک کلرلا وولگاریس، نمونه­های آب خروجی از تصفیه­خانه­ی مرکزی شهرستان گرگان جمع­آوری شد. 2 تیمار و 1 شاهد این آزمایش که هر کدام شامل 6 تکرار بود پساب­هایی با 100%، 50% و 0% رقت بودند. نتایج نشان داد که جلبک...

[ 8 ] - جذب کادمیوم(II) از محلول های آبی با استفاده از پسماند کارخانه پشم سنگ

این پژوهش، ابتدا برخی از خصوصیات پسماند پشم سنگ مانند pH، EC، pHZPC، ترکیب شیمیایی با استفاده از آنالیز‌‌های XRD و XRF و همین‌طور ساختار و ریخت‌شناسی جاذب‌ها با استفاده از میکروسکوپ الکترونی رویشی(SEM) تعیین شد. آزمایشات جذب به صورت ناپیوسته با استفاده از محلول‌های آزمایشگاهی حاوی فلز سنگین کادمیوم انجام گرفت و شرایط بهینه جذب در اثر فاکتورهای مختلف pH(3، 5، 7 و 9)، غلظت اولیه یون‌های فلزی(1، 5...

[ 9 ] - Phosphate and nitrate removal from municipal wastewater by algae Scenedesmus obliquus cultivation and production of algal biomass

Nitrate and phosphate are abundant in urban wastewater. We evaluated the efficiency of nitrate and phosphate removal from wastewater by Scenedesmus obliquus and its use as a medium for Scenedesmus obliquus. Samples were collected from the effluent of central wastewater treatment in Gorgan. This experiment was done by 3 treatments and 6 replications that effluent with 100%, 50% and 0% were dilut...

[ 10 ] - Effects of nutrients on the primary production and determination of the restricting factors in primary production in the international wetland of Choghakhor (Iran)

Limitations in nutrients and physicochemical parameters play a key role in aquatic ecosystems. The present study aimed to determine the influential physicochemical factors in the chlorophyll-a content for wetland management by identifying the restricting factors in primary production. Sampling was conducted during March 2017-February 2018. Factors such as water salinity, temperature, pH, nitrat...
