چکیده مقاله :
زمینه و هدف: آلودگی آب به فلزات سنگین یکی از معضلات مهم محیط زیستی است که با ایجاد بیماری های جدی، زندگی و سلامتی انسان ها را تحت تاثیر قرار می دهد. لذا ضروری است که حضور آن ها در محیط کنترل شود. علیرغم استفاده زیاد فلز روی در صنایع و آلودگی منابع آبی توسط پساب های حاوی آن و مشکلات ناشی از حضور این فلز در آب های آشامیدنی، تحقیقی در رابطه با استفاده از نانوذرات کیتوسان که برگرفته از پسماند کارگاه های تکثیر و پرورش ماهی و میگو هست برای حذف بهینه این فلز از منابع آبی، انجام نگرفته است. روش بررسی: تحقیق حاضر در سال 1398 در دانشگاه جیرفت انجام شد و در آن حذف فلز روی از فاضلاب صنایع با استفاده از نانوکامپوزیت کیتوسان اکسید گرافن تحت تاثیر فاکتورهای pH، غلظت نانوکیتوسان، غلظت فلز روی و مدت زمان تماس بر ظرفیت جذب این فلز تعیین گردید. محدوده متغیرها 7-2 برای pH، g/l 5/0-01/0 غلظت نانوکیتوسان، mg/l 200-10 غلظت روی و 420-30 دقیقه زمان تماس بودند.یافته ها: براساس نتایج در pH برابر 4، غلظت جاذب g/l 01/0، غلظت یون رویmg/l 200 و زمان تماس 420 دقیقه، بالاترین ظرفیت جذب mg/g 2/89 به دست آمد. عملیات بازجذب و استفاده دوباره از جاذب نیز انجام و پس از 4 تکرار در فرآیند جذب، ظرفیت جذب مقدار 35/19 به دست آمد.بحث و نتیجه گیری: براساس یافته ها نانوکامپوزیت کیتوسان اکسید گرافن جاذبی موثر با قابلیت جذب بالای فلز روی می باشد.
چکیده انگلیسی:
Background and Objective: Water pollution with heavy metals is one of the most important environmental problems that affect human life and health by causing serious diseases. Therefore, it is necessary to control their presence in the environment. Despite the high use of zinc in industry and the pollution of water resources by effluents containing it and the problems caused 0062002y the presence of this metal in drinking water, a study on the use of chitosan nanoparticles taken from the waste of fish breeding workshops and Shrimp has not been done to optimally remove this metal from water sources.Method: Here, a nanocomposite of chitosan and graphene oxide was synthesized at the University of Jiroft in 2019 and used for removal of zinc metal from industrial wastes. The effects of initial solution pH (2-7), chitosan/graphene oxide bio-sorbent dose (0-1.5 g/l), initial zinc (II) concentration (10-200 mg/l) and contact time on the uptake capacity of metal (30- 420 min) were investigated.Findings: This nanocomposite was exhibited the highest metal ions uptake capacity (89.2 mg/g) at pH value of 4.0, biomass dose 0.01 g/l, metal concentration of 200 mg/l and contact time 420 min. The structural stability and efficient adsorption capacity of adsorbent was proved after four times adsorption–desorption cycles and after that uptake capacity was 19.35 mg/g.Discussion and Conclusion: The results showed that the synthesized nanocomposite from chitosan and graphene oxide could be used as a potentially good adsorbent to remove Zn2+ simultaneously in aqueous solutions.
