Abstract
In Colombia in 2015, 406,078 tons of hazardous waste were produced, of which about 28%
were discarded untreated. In this sense, the tannery sector uses chromium salts to stabilize
the collagen fibers, adding chromium to the process effluent. Chromium is a heavy metal,
which due to its bioaccumulation and persistence in water generates environmental and
health problems. For this reason, a nanocomposite with reduced toxicity and low cost, with
an iron oxide core coated with titanium oxide was developed to remove chromium from
effluents.
