Comparative Studies on Colour and COD Removal of Reactive Dyes by a Novel Steel Scrap as a Catalyst with Conventional Fenton Process
Abstract
Aim: To remove the colour and COD of two reactive dyes namely reactive blue and yellow by Fenton
and modified Fenton processes. Materials and Methods: The total number of groups used in this
study is two (Control group N = 16 and Experimental group N = 16).The sample size was taken as 16
after being calculated for a pre-test power of 80% with an alpha value of 0.05 in clinical.com. The
removal of colour and COD of two reactive dyes by Fenton process and modified fenton process was
carried out. Results and Discussion: Colour removal upto 90% and 95% by Fenton and modified
Fenton Processes respectively. The best COD removal efficiencies were 65.54 %, and 57.92% in the
case of reactive yellow and reactive blue dyes in the Modified Fenton Process respectively. In the
modified fenton process steel scrap is replaced instead of FeSO4. Conclusion: Compared to the
Fenton process, the modified Fenton process has more percentage of colour and COD removal
within the limits of the study.
