Efficient adsorptive removal of tetracycline from aqueous solution using phytosynthesized nano-zero valent iron

Recently, nano-zero valent iron (nZVI) has been identified as one of the most promising materials for the removal of a wide range of pharmaceuticals in water. However, nZVI effectiveness in aqueous media is dramatically reduced due to its aggregation and instability. To overcome these problems, castor oil (Ricinus communis Linn.) leaves aqueous extract has been used in this study as a reducing and stabilizing agent to increase the stability of...
