A STUDY ON THE REDUCTIVE DECHLORINATION OF CHLOROFORM WITH NANO Fe/Cu BIMETALLIC PARTICLES IN AQUEOUS SOLUTION Author Phan Kim Nguyen, Bui Xuan Vung University of Education –The University of Danang;[.]

A STUDY ON THE REDUCTIVE DECHLORINATION OF CHLOROFORM WITH NANO Fe/Cu BIMETALLIC PARTICLES IN AQUEOUS SOLUTION Author: Phan Kim Nguyen, Bui Xuan Vung University of Education –The University of Danang; vungxuanbui@gmail.com Abstract: In this work, nano-Fe/Cu bimetallic particles are synthesized and used to reduce chloroform to methane in aqueous solution The synthesized particles are characterized by X ray diffraction (XRD) pattern, Transmission electron microscopy (TEM) images and energy dispersive X ray (EDX) analysis Such key parameters on the reduction of chloroform as pH, nano-Fe/Cu dosage, treatment time have been investigated Closed batch experiments have been conducted for this investigation Experimental results show that the de-chlorination of 50 mL of 20 ppm chloroform aqueous solution has the highest degradation efficiency of 88.93% under the experimental conditions such as pH = 3, reaction time of 30 minutes and nano-Fe/Cu dosage of 0.05 gram GC-MS analysis for a 20 ppm chloroform aqueous solution before and after treatment has shown that there is no formation of such products containing chlorine as CH2Cl2 and CH3Cl Key words: Nano-Fe/Cu; Degradation; Aqueous solution Bimetallic particles; Chloroform; De-chlorination;
