KUNZ, Airton; PERALTA-ZAMORA, Patricio; MORAES, Sandra Gomes de  and  DURAN, Nelson. New tendencies on textile effluent treatment. Quím. Nova [online]. 2002, vol.25, n.1, pp.78-82. ISSN 0100-4042.

Textile effluents, when not correctly treated, cause a high impact to the environment. The main recalcitrant compounds present in textile effluent are represented by the synthetic dyes, used during the fibber dying process. Among others, the azo dyes are considered the most harmful due to its mutagenic and carcinogenic character. In the present work we reported a revision study on the new tendencies for remediation of textile effluents, mainly to degrade the recalcitrant compounds. For this purpose, chemical, physical, photochemical, biological and combined processes were investigated.

Keywords : textile effluents; treatment processes; recalcitrant compounds.
