چکیده

هدف از این پژوهش، مقایسه کارایی دو فرایند پرسولفات فعال‌شده توسط Fe2+ و الکترو پرسولفات در حذف محلول اسید آبی 25 بود. بدین منظور، تأثیر پارامترهای pH، غلظت رنگزا، غلظت پرسولفات سدیم و غلظت سولفات آهن (II) مورد بررسی قرار گرفت. طبق نتایج حاصل پس از 60 دقیقه، حذف 92 درصد رنگزا تحت 3pH = ، غلظت mg/L 50 رنگزا، غلظت mg/L 500 نمک پرسولفات سدیم و غلظت mg/L 100 نمک سولفات آهن (II) در فرایند پرسولفات فعال‌شده با Fe2+ و حذف 95 درصد رنگزا در 5= pH ، غلظت mg/L 200 رنگزا، غلظت mg/L 500 نمک پرسولفات سدیم و غلظت mg/L 100 نمک سولفات آهن (II) در فرایند الکترو پرسولفات با استفاده از دو الکترود گرافیت صورت گرفت اما در شرایط مذکور پس از زمان مشابه 180 دقیقه حذف حدود 90 درصد COD در هر دو فرایند ‌ حاصل شد. نتایج بررسی سینتیک‌ واکنش نشان داد که استفاده از فرایند الکترو پرسولفات موجب افزایش سرعت واکنش از mg/L/min 0016/0 تا mg/L/min 0487/0 می‌شود. مقایسه این دو فرایند نشان داد استفاده از فرایند الکتروشیمیایی موجب بهبود قابلیت فرایند پرسولفات فعال‌شده با Fe2+ و انجام عمل تصفیه در pH نزدیک به pH طبیعی رنگزا (مصرف مواد شیمیائی کمتر) و حذف رنگزا با غلظت بیشتر (4 برابر) می‌شود.

چکیده [English]

The purpose of this study was to compare the performance of Fe2+ activated persulfate and electro-persulfate process in Acid Blue 25 removal from aqueous solution. For this reason, the effects of different parameters including pH, dye, sodium persulfate and ferrous sulfate concentrations were investigated. The removal efficiency of 92% at the time of 60 minute was obtained at pH= 3, dye concentration= 50 mg/L, sodium persulfate concentration= 500 mg/L and Fe (II) sulfate concentration= 100 mg/L for Fe2+ activated persulfate system and the removal efficiency of 95% at pH= 5, dye concentration = 200 mg/L, sodium persulfate concentration = 500 mg/L and ferrous sulfate concentration = 100 mg/L for electro-persulfate system by means of graphite materials as the neutral electrodes. COD removal efficiency in Fe2+ activated persulfate and electro-persulfate in the mentioned conditions were 90% and 89% in 180 minutes, respectively. Moreover, the result of process kinetics showed that using electrochemical process improved the reaction velocity from 0.0016 to 0.0487 mg/L/ min. The comparison between these two-process showed that using electrochemical process improved dye removal efficiency by 4 times.
