چکیده

زمینه و هدف  هیدروکربن‌های پلی‌آروماتیک[1] بر سلامت انسان و محیط‌زیست در کوتاه‌مدت و بلندمدت تأثیرات منفی متعددی دارد. در این مطالعه به بررسی سیستماتیک مطالعات انجام شده در زمینه حذف PAHs از خاک‌های آلوده با استفاده از روش الکتروکنیتیک و تعیین پارامترهای تأثیرگذار بر این فرایند پرداخته شده است.
مواد و روش‌‌ها این تحقیق، یک مطالعه مروری نظام‌مند می‌باشد. برای این منظور، ابتدا کلیدواژه‌های مرتبط با آلاینده‌های نفتی و روش الکتروکنتیک تهیه شد. جستجو در پایگاه‌های علمی شامل Scopus،  Web of Scienceو PubMed انجام گرفت. پس از اتمام جستجو در هر پایگاه مقالات به نرم‌افزار Endnote منتقل شد و غربالگری تا رسیدن به مقالاتی که کاملاً به موضوع ارتباط دارند انجام گردید.
یافته‌ها به‌طور کلی571 مقاله تا تاریخ 10 سپتامبر سال 2018 از پایگاه‌های ذکر شده پیدا گردید. سپس با حذف موارد تکراری و موارد غیرمرتبط با موضوع، 10 مطالعه موردبررسی دقیق قرار گرفت. مطالعات بررسی شده مربوط به سال‌های 2000 تا سال 2017 بود. در سه مطالعه از روش الکتروکنتیک به همراه سورفاکتانت‌ها و بیوسورفاکتانت‌ها شده بود. چهار مطالعه از روش تجزیه زیستی به همراه فرایند الکتروکنتیک بهره برده بود. تلفیق فرایند الکتروکنتیک با سایر فرایندها می‌تواند کارایی این فرایند را در حذف PAHs از خاک تا حد بسیار بالایی در زمان‌های نسبتاً کوتاه (کمتر از 1 ماه) افزایش دهد.
نتیجه‌گیری با توجه تأثیرگذاری پارامترهای مختلف بر فرایند، انجام یک پایلوت آزمایشگاهی برای بهینه گرفتن فرایند قبل از اجرای این روش به صورت میدانی توصیه می‌گردد.

چکیده [English]

Introduction: Polycyclic aromatic hydrocarbons (PAHs) have several adverse effects on human health and environment in the short and long term. In this study, a systematic review of the studies carried out to date on the removal of PAHs from contaminated soils by electrokinetic method and determining the parameters affecting this process has been investigated. Materials and Methods: This research is a systematic review study. For this purpose, the keywords related to PAHs pollutants and electrokinetic methods were first prepared. Search in scientific databases including Scopus, Web of Science and PubMed was done. After completion of the search, the findings of search was transferred to the Endnote software and screening was done to reach articles that are fully related to the subject. Results: A total of 571 articles were found until September 10, 2018 from the mentioned data basis. Then, 10 studies were carefully reviewed after removing duplicates and non-compliant items. The included studies were from 2000 to 2017. In 3 studies, electrochemical methods with surfactants and biosurfactants were used. Four studies utilized biodegradation techniques along with electro-kinetics. Combination of the electrokinetic with other processes can increase the efficiency of this process in removing PAHs from soil in a short period (less than 1 month). Conclusion: Considering the influence of different parameters on the process, it is recommended to conduct a pilot test to optimize the process before the implementation of this method.
