چکیده

Abstract This study investigated the feasibility of using sodium hypochlorite as an advanced oxidation process to remove Acid Orange 12 azo dye from wastewater. For this purpose, batch reactor experiments were done. Several variables address efficiency considered. These are initial pH (5, 7, and 9), concentration (50 – 250 mg/l), temperature (20-50) degrees Celsius, time electrolysis (1-75) min. also investigate effects UV on was Experimental results showed that color removal NaOCl with is more effective than alone. The highest obtained by increasing (50-250mg/l) at PH=5. When solution increased °C, increased, same time, required reduced (20-5) minutes obtain efficiency. kinetic follows a second-order reaction. thermodynamic functions indicate response spontaneous, endothermic, increases randomness.

Using Eggshell in Acid Orange 2 Dye Removal from Aqueous Solution

Background and purpose: Generated dye wastewater by the textile industry is usually toxic, non-biodegradable and resistant in the environment. Eggshell is one of the inexpensive material and for the reason the vesicular structures can be used as a proper adsorbent for pollutants removal. The aim of this study is to investigate the efficiency of eggshell for removal of acid orange 2 dye from aqu...
