Resumen
The demand for textile products has grown progressively in current consumer society,
textile garments are bought, used and discarded at a disturbing speed. Among the
different chemical products used in the multiple production processes in the textile
industry, the massive use of colorants stands out. The increase in textile production has
generated a high demand for water with the subsequent production of colored
wastewater. This kind of water is the focus of concern due to the issues generated by
them; Furthermore, to counteract this problem, water quality management processes
have been proposed that include the regulation and reduction of highly toxic and
dangerous pollutants, such as textile dyes. The aim of this study is the review of the state
of the art of the occurrence and risks of dyes in effluents from textile factories and the
analysis of the proposals for their removal through heterogeneous photocatalysis.
Therefore, a bibliographic review has been carried out addressing: 1) the current national
and international legislation on colorants in wastewater; 2) The occurrence of dyes in
wastewater and water bodies; 3) the toxicity of dyes in living beings and 4) analysis of
photocatalytic methods for the removal of emerging pollutants.
