چکیده

در سال‌های اخیر توجه زیادی بر روی حذف رنگ از پساب‌های صنایع نساجی صورت گرفته است که نه تنها به‌دلیل سمیّت این پساب‌ها بلکه به‌دلیل ظاهر ناخوشایندی است که به پساب می‌دهند. روش‌های مختلفی برای حذف رنگ مورد استفاده قرار گرفته است. یکی از رایج‌ترین روش‌های مؤثر و ارزان قیمت، فرایند جذب سطحی است. در این پژوهش نانوکامپوزیت پلی‌آنیلین- مولیبدوفسفات قلع (II) به روش ساده و مقرون به صرفه‌ای سنتز شد. برای شناسایی نانوکامپوزیت سنتز شده از آنالیزهای دستگاهی FT-IR، XRD ، EDS، BET، TEM و FESEM استفاده شد. سپس کارایی نانوکامپوزیت تهیه شده در حذف رنگزای راکتیو نارنجی 122 بررسی شد. نتایج حاصل از SEM نشان داد که اندازه ذرات در حدود 80 نانومتر بوده و ساختار آن با توجه به طیف XRDبه‌حالت آمورف است. نتایج نشان داد که فرایند جذب در 40 دقیقه به تعادل می‌رسد و مقدار حذف با افزایش دز جاذب افزایش و با افزایش غلظت رنگزا و pH کاهش می‌یابد. مطابق نتایج ایزوترم جذب سطحی، جذب رنگزای راکتیو نارنجی 122 بر روی نانوکامپوزیت پلی‌آنیلین مولیبدوفسفات قلع II از ایزوترم لانگمیر تبعیت می‌کند و حداکثر ظرفیت جذب رنگزا توسط 42/47 میلی‌گرم بر گرم به‌دست آمد. نتایج آزمایش‌ها نشان داد که 1/0گرم از نانوکامپوزیت قادر به حذف 56/87 درصد از رنگزای راکتیو نارنجی 122 در غلظت اولیه 50 میلیگرم در لیتر و درpH برابر 2 است.

چکیده [English]

In the last few years, color removal from textile industries has been given much attention because of its potential toxicity and visibility problem. There have been various promising techniques for the removal of dyes. Adsorption is one of the most popular, effective and economic methods. Nanocomposite of polyaniline-molybdophosphatetin(II) was synthesized by polyaniline and molybdophosphatetin(II) via simple and easy method and was characterize by FTIR, XRD, FESEM, TEM, BET and EDS. Then, the efficiency of synthesized nanocomposite was investigated  on the removal of Reactive Orange 122 dye. FESEM and XRD data reveled that  the size of nanocomposite was 80 nm and  its structure was  amorphose. As results, dye adsorption onto nanocomposite was reached to equilibrium at 40 min. Also, its removal increased by increasing of nanocomposite dosage and decreasing of pH and dye concentration. Isotherm adsorption studied cionfirmed the Reactive Orange 122 dye adsorption onto polyaniline-molybdophosphatetin (II) was obeyed Langmuier isotherm and the maximum adsorption capacity for removal of Reactive Orange 122 dye by polyaniline-molybdophosphatetin(II) was obtained about 47.42 mg/g. The maximum removal of Reactive Orange 122 dye (87.56%) by polyaniline-molybdophosphatetin(II) was obtained at pH =2, 0.1g/250ml of nanocomposite, and 50mg/L of dye concentration.
