[ 1 ] - Biodegradation of methylene blue from aqueous solution by bacteria isolated from contaminated soil
The use of biodegradation methods by microorganisms in the removal of industrial dyes are widely considered owing to their high efficiency and compatibility to the environment. Therefore, this study aims to evaluate the biodegradation of methylene blue (MB) from aqueous solution by bacteria isolated from contaminated soil. This study was performed in laboratory scale on bacteria isolated and pu...
[ 2 ] - Using geographic information system (GIS) and remote sensing (RS) in zoning nitrate concentration in the groundwater of Birjand, Iran
Previous studies have shown that the presence of nitrate in drinking water can cause several diseases especially in the infants, such as cancer and blue baby. The Environmental Protection Agency (EPA) has since adopted the 50 mg/l standard as the maximum contaminant level (MCL) for nitrate for regulated public water systems. This study aimed to evaluate the concentration of nitrate in the drink...
[ 3 ] - بررسی حذف سفالکسین از محیط‌های آبی با استفاده از مونت موریلونیت سبز بارگذاری شده با نانوذرات TiO2 در حضور پرمنگنات پتاسیم
هدف: به دلیل مضرات آنتی‌بیوتیک‌ها در اکوسیستم، باید قبل از تخلیه پساب‌های حاوی آن‌ها به داخل محیط توسط یک فرایند موثر حذف شوند. هدف از این مطالعه حذف سفالکسین توسط مونت موریلونیت سبز محلی بارگذاری شده با نانوذرات TiO2 (TiO2/GLM) در حضور پرمنگنات پتاسیم بوده است. مواد و روش‌ها: این تحقیق تجربی به صورت ناپیوسته انجام شده است. در این مطالعه، از مونت موریلونیت سبز (Green Local Montmorillonite) یاف...
[ 4 ] - بررسی کارایی حذف کروم شش ظرفیتی از محلول‌های آبی با استفاده از کربن فعال پودری تولیدی تحت تأثیر امواج فراصوتی
Background and Aim: Activated carbon is a most common adsorbent. By emerging of new technologies, the activated carbon production methods need to be improved. The aim of this study was producing powdered activated carbon from Peganum Harmala seed under ultrasound waves for activation and its application for chromium removal from aqueous solutions. Materials and Methods: This experimental stu...
[ 5 ] - بررسی احیای فتوکاتالیستی کروم شش‌ظرفیتی توسط نانوذرات سبز آهن در محلول‌های آبی: یک مطالعه آزمایشگاهی
Background and Objective: Hexavalent chromium (Cr (VI)) is a highly toxic pollutant that isknown as a carcinogen and mutagen agent to humans. Photocatalytic reduction is one of the known ways to remove these contaminants. Therefore, the aim of this study was to investigate the catalytic effect of green iron nanoparticles, as eco-friendly materials, on photocatalytic reduction of Cr (VI) from wa...
[ 6 ] - بررسی حذف کروم شش‌ظرفیتی از محلول‌های آبی با استفاده از کربن فعال گرانولی و پودری تولید‌شده از دانه اسپند
Background and Objectives: Because of toxical and hazardous properties of hexavalent chromium (Cr(VI)), its removal by an economical and efficient method is necessary. The use of activated carbon, as an adsorbent, is a common and effective method for hexavalent chromium removal. Thus the aim of this study was to produce granular and powdered activated carbon form Peganum Harmala and compare the...
[ 7 ] - بررسی حذف کروم شش ظرفیتی با استفاده از دانه گرانولی اسپند از فاضلاب سنتتیک
Background and Aim: Discharge of industrial wastewater containing hexavalent chromium into the environment can have harmful effects to the types of organisms. So, chromium should remove before discharging to the environment with an effective method. The purpose of this study of is hexavalent chromium removed with Peganum harmala granular seeds(PGS). Materials and Methods: In this experim...
