RemovalofCoraleleNavyBlue3DDyefromActivatedCarbon Synthesized from Paper Mill Sludge

Abstract

The adsorption capacity of activated carbon synthesized from sludge from paper mills is 
investigated. Converting of paper mill sludge to adsorbent like activated carbon is a significant 
process since it decreases environmental problems connected with disposal of waste sludge. The 
dye (Coralele Navy Blue 3G) adsorption on activated carbon generated from paper mill sludge from 
synthetic textile waste water (STW) was investigated. The experimental design and data analysis 
were done using four factors and a full factorial central composite design based on response surface 
methodology (RSM). Initial dye concentration: 40-120 mg/l, Adsorbent dose: 1-10gm/l, pH 3-9, and 
contact time: 0-150 minutes were used as input parameters, with percentage dye removal being the 
system's reaction. The ideal situation values of operational parameters are found to be initial dye 
concentration: 80 mg/l, Adsorbent dose: 5.5 gm,Contact time:150 minutes, and pH:6. Optimum dye
