Effect of lime on speciation of heavy metals during composting of water hyacinth

Jiwan SINGH,Ajay S. KALAMDHAD

Frontiers of Environmental Science & Engineering 2016, Volume 10, Issue 1,   Pages 93-102 doi: 10.1007/s11783-014-0704-7

Abstract: However, the major disadvantage of water hyacinth composting is the high content of heavy metals in thelime sludge significantly reduced most bioavailable fractions (exchangeable and carbonate) of heavy metalsTessier sequential extraction method was employed to investigate the changes in speciation of heavy metalsEffects of physicochemical parameters such as temperature, pH and organic matter on speciation of heavy metalsAddition of lime was very effective for reduction of bioavailability of heavy metals during composting
