Abstract :
The present work was aimed at studying the effect of biologically produced ferric sulphate on metal removal. By using biologically produced ferric sulphate the amount of 1.40, 1.10, 0.44, 0.40, and 3.016 g/L mass was removed for copper (6 h), nickel (10 h), zinc (8 h), aluminium (36 h) and tin (72 h) respectively. These interesting results motivate further the use of biologically produced ferric sulphate for mobilization of metals from electronic waste. A sustainable recycling process can be established for extraction of metals from electronic waste by using biologically produced ferric sulphate.
