Elemental sulfur has been used as a binding agent for the treatment of heavy metal containing waste residues.However, the use of elemental sulfur alone could not satisfactorily immobilize heavy metals in the residues.Therefore, Seven additives, namely NaOH, Na2SO3, Ca(OH)2, NaNO2, Na2S2O3·5H2O, Na2S·9H2O and Na2CO3 have been investigatedto enhance the immobilization effect of heavy metals in the sulfur immobilization process.
