Removal of synthetic dyes from wastewaters: a review

Environ Int. 2004 Sep;30(7):953-71. doi: 10.1016/j.envint.2004.02.001.


The more recent methods for the removal of synthetic dyes from waters and wastewater are complied. The various methods of removal such as adsorption on various sorbents, chemical decomposition by oxidation, photodegradation, and microbiological decoloration, employing activated sludge, pure cultures and microbe consortiums are described. The advantages and disadvantages of the various methods are discussed and their efficacies are compared.
