چکیده

زمینه و هدف: پساب ‌صنایع نساجی حاوی مقدار قابل توجهی از آلاینده های سمی و آلی می باشد. به علت خطرات بهداشتی از قبیل سرطان‌زایی و جهش‌زایی، تخلیه این دسته فاضلابها در منابع آبی می تواند مخاطرات بهداشتی دربرداشته باشد. هدف ازاین تحقیق، بررسی کارائی حذف رنگزای بازیک بنفش 16 (BV16) از محلول های آبی با استفاده از کیتوزان استخراج شده از ضایعات میگو می‌باشد.
 
مواد وروش ها :در این مطالعه تاثیر پارامترهای مختلف از قبیل زمان تماس، غلظت اولیه رنگزا، غلظت جاذب و pH بر روی میزان جذب مورد بررسی قرار گرفت. غلظت باقیمانده رنگزا با استفاده از دستگاه اسپکتروفتومتر در طول موج nm 545 قرائت شد. داده‌های جذب با ایزوترم‌های لانگمیر، فروندلیخ و سینتیک‌های واکنش شرح داده شدند.
 
یافته ها: نتایج نشان داد با افزایش زمان تماس و افزایش دوز جاذب، میزان حذف رنگ توسط جاذب افزایش و با کاهش غلظت اولیه رنگزا، میزان حذف افزایش یافت. بر طبق نتایج بدست آمده، جذب رنگزا بر روی این جاذب از ایزوترم فروندلیچ با 99/0<2R تبعیت می کند.
 
نتیجه گیری: نتایج حاصل از این مطالعه نشان داد که میتوان از کیتوزان استخراج شده از ضایعات میگو به عنوان یک جاذب نسبتاً کارآمد جهت حذف رنگزای بازیک بنفش 16 در محلول های آبی استفاده نمود.

چکیده [English]

Background & Objective: Textile effluents contain significant amounts of toxic and organic pollutants. Due to health risks such as carcinogenic and mutagenic effects, discharge of this kind wastewater to water resources can lead to health impacts. The aim of this study was to survey the efficiency of Chitosan derivative in removal of basic dyes violet16 from aqueous solutions.
 
Materials & Methods: In this study the influence of different parameters including contact time, initial dye concentration, adsorbent concentration, and PH, was studied. Residual of dye concentration was measured using a spectrophotometer set in 545 nm wavelength. Adsorption data was described by Langmuir and Freundlich isotherms and kinetic reactions.
 
Results: The results showed that increasing contact time and adsorbent dose enhances dye removal rates for this adsorbent. By decreasing initial concentration of dye, removal rates increased. In optimal conditions, Chitosan derivatives were able to remove dye 68 percent respectively. For this adsorbents optimum pH was obtained 10. According to the results, adsorption process for both adsorbents was determined by Freundlich isotherm by R2>0.98. Dye absorption kinetic of both adsorbents followed pseudo second degree by R2>0.98.
 
Conclusion: the results showed that Chitosan derivative can be applied as an efficient adsorbent for removal basic violet 16 dye from aqueous solutions.
