Recent advances in decolourization of dyes using iron nanoparticles: A mini review

Water is the most abundant resource present on earth however due to un-constrained human activities it is getting highly polluted. Wastewater generated from many industries is a major water pollution problem worldwide. One of the most concerned industrial contaminants present in wastewater is dyes from many industries, majorly being dyeing and textile industries. The first visual indicator of pollution is colour leading from dyes. Due to various environmental and health impacts, it is very important to either remove or degrade dyes present in industrial effluents before their disposal. The present study focuses on sources of dyes present in wastewater streams and their detrimental effects. The study also highlights the usage of iron nanoparticles by various researchers all around the world for the removal of these dyes and the various parameters that affect the efficiency of the iron nanoparticles for dye removal.
