Floating and Magnetic Composite Based on FeMnO3/ ACC: An Efficient Adsorbent for Removing Toxic Dyes in Aqueous Media

Resumo

Lately, despite the scarcity of water resources, there has been a significant and unsustainable increase in
global freshwater consumption, driven by the expanding industrial activity and world population. Water
pollution by organic compounds such as dyes, has attracted the attention of the scientific community and
government agencies. These pollutants are typically highly toxic, persistent, and prone to bioaccumulation
in the environment. Despite these characteristics, they are used in substantial quantities and continually
introduced into the aquatic environment, directly impacting animals, humans, and biodiversity. Therefore,
in this context, adsorption has gained notoriety due to its high performance, accessibility, simplicity,
applicability, and low cost. In this sense, the present work describes the preparation, characterization and
application of a magnetic and floating adsorbent composite designed for the removal of toxic organic
dyes from the aqueous medium. The application of the composite showed that it is possible to reduce
the toxicity of solutions by up to 70%.
