Analysis of various iron nanoparticles and compounds in pulp & paper mill waste water treatment

Pratibha Singh, Nupoor Srivastava, Prashant Singh


The pulp and paper industry waste water is characterized by dark color, foul odour, high organic content & extreme quantities of COD, BOD & chlorinated compounds. These impurities removed by chemical precipitation using ferric chloride and iron nanoparticles. Today iron nanoparticles used for detection and removal of chemical and biological substances include metals, nutrients and chlorinated organic compounds. Iron nanoparticles reveal good result than other chemical techniques used in pulp and paper mill effluent treatment. Iron nanoparticles are widely used in contaminated with chlorinated organic compounds. In present study two samples of pulp & paper mill effluent treated with FeCl3 & iron nanoparticles. It was observed that the concentration of FeCl3 in the sample was high but treatment was less effective while the concentration of iron nanoparticles used in other sample was very low but the treatment was very effective. Iron nanoparticles are highly reactive because of their large surface area, In the presence of oxygen & water they rapidly oxidize to form free iron ions and this treatment process is environmental friendly.
