چکیده

حضور مواد رنگ‌زای آلی در پساب‌ها یکی‌ از نگرانی‌های ویژه در محیط‌زیست به‌شمار می‌رود. از‌این‌رو تصفیه پساب‌های حاوی مواد رنگ‌زا برای محیط‌زیست، اهمیت زیادی دارد. استفاده از جاذب‌های مغناطیسی روشی نوین و همچنین با کارایی زیاد برای حذف مواد رنگ‌زا از محیط‌های آبی است. در این پژوهش، به‌منظور حذف مالاشیت سبز از جاذبی سبز که در ساختار آن پودر جلبک اسپیرولینا که با بیوپلیمر طبیعی کیتوزان عامل‌دار شده است، استفاده شد. جاذب سنتز شده با آنالیزهای VSM، XRD و FTIR مشخصه‌یابی شد. به‌منظور بهینه‌سازی فرایند از نرم‌افزار طراحی آزمایش‌ها و روش پاسخ سطحی در طرح مرکب مرکزی استفاده شد. پارامترهای تأثیرگذار در فرایند جذب شامل pH محلول، دوز جاذب، زمان تماس و غلظت اولیه رنگ مالاشیت سبز بررسی شد. نتایج آنالیز واریانس داده‌ها نشان داد که اثرات متغیرهای مستقل pH، دوز جاذب، غلظت اولیه، زمان انجام واکنش و همچنین اثرات مجذور متغیرهای pH، دوز جاذب، غلظت اولیه و زمان، برهم‌کنش بین فاکتورهای pH به غلظت اولیه، pH اولیه به زمان واکنش، برهم‌کنش غلظت اولیه به زمان و همچنین برهم‌کنش بین دوز جاذب و زمان در مدل معنی‌دار هستند و همچنین پارامتر pH محلول، بیشترین تأثیر را پارامترهای عملیاتی دارد. همچنین مدل هم‌دمای فروندلیچ به‌منظور توصیف رفتار تعادلی فرایند جذب توانایی بیشتری دارد. کامپوزیت مغناطیسی اسپیرولینا/کیتوزان قادر به حذف بیش از 99 درصد مالاشیت سبز از محلول آبی تحت شرایط pH معادل 75/6، دوز جاذب برابر با mg/L230، غلظت اولیه رنگ 4 میلی‌گرم در لیتر و زمان 90 دقیقه بود.

چکیده [English]

The presence of organic dyes in wastewater is one of the special concerns in the environment. Therefore, the treatment of wastewater that contains dyes has great importance for the environment. The use of magnetic adsorbents is a new and highly efficient method to remove dyes from water environments. In the structure of the absorbent, Spirulina algae powder was made into a biopolymer called chitosan. The synthesized adsorbent was characterized by XRD, VSM and FTIR analysis. In order to optimize the process, experimental design software and surface response method were used in the central composite design. The influencing parameters in the adsorption process including solution pH, adsorbent dose, contact time and initial concentration of malachite green dye were investigated. The results of the analysis of variance showed that the effects of the independent variables pH, dose, initial concentration, and time, as well as the square effects of the variables pH, dose, initial concentration, and time, the interaction between pH and initial concentration, the pH to reaction time, the initial concentration to time, and the interaction between dose and time in the model, were significant, as was the pH parameter of the solution, which had the greatest effect among the operating parameters. Freundlich isotherm model was also more capable of describing the equilibrium behavior of the adsorption process. Magnetic composite Spirulina/chitosan was able to remove more than 99% of malachite green from aqueous solution under pH conditions=6.75, adsorbent dose=230 mg/L, initial dye concentration 4 mg/L and time 90 minutes.
