Abstract
The leather tanning sector is one of the most representative industrial activities in the Colombian economy, with a share of 2.17% in the manufacturing GDP, mostly grouped into SMEs through the export of wet-blue type leather generating revenue of $ 70 million a year. However, an undue exploitation of the activity, as well as manufacturing practices that are not very aware of the environmental impact generated mainly by hexavalent chromium, generates concern both for the environmental effects and for the harmful effects on the health of the population of Bogotaná. The present article establishes through a literature review the conventional and future treatments for the removal of heavy metals, taking hexavalent chromium as a model, proposing a nanomaterial that solves the problem in wastewater.
