UAT researcher develops biodegradable material to purify water

Researchers at the Universidad Autónoma de Tamaulipas (UAT) have developed a sustainable, low-cost biocomposite designed to filter heavy metals from water resources. Led by chemical engineering graduate María Fernanda González Arellano and advised by Dr. Juan Roberto de la Torre Escareño, the innovation specifically targets hexavalent chromium (CrVI), a highly toxic and carcinogenic contaminant that is difficult to remove using conventional methods.

The biodegradable material is composed of a matrix of thermoplastic starch, chitosan, and fibers extracted from the pods of the flamboyant tree (Delonix regia). The production process involves four distinct stages: collection, grinding, formulation, and thermopressure.

Experimental evaluations, including spectroscopic analysis, confirmed the material's ability to adsorb heavy metals. Technical studies also validated the biocomposite's stability in aqueous media and its potential for scaling to industrial pilot levels. Due to its environmental impact and viability, the UAT has initiated the patent process for the technology.
