Production of organic dyes has increased in recent years and the textile industry has the main final application and contributes to the accumulation of non-biodegradable toxic compounds that lead to the water quality degradation. There are different methods for removing these compounds through wastewater treatment, however conventional methods do not provide satisfactory dye removal. In this sense, the dye removal process using photocatalysis is considered the most efficient and promising method. Thus, the present work aims to synthesize and characterize composites formed between poly (4-aminobenzoic acid) and Cd/La bimetallic oxide, in order to study their activity in the photodegradation of the malachite green dye. The chemical structure of these materials was characterized Artigo Original Original Article Artículo Original Artigo recebido em 06/06/2020 aprovado em 15/10/2020 publicado em 12/03/2021. 76 using vibrational spectroscopy and the results confirm the obtaining of the proposed compounds. The band gap energy of the catalyst was determined to be 2.76 eV. The kinetics were determined as pseudo-first order for the catalyst and second order for the composite. The kinetic study determined that the use of poly (4-aminobenzoic acid) increases the efficiency of photocatalysis by 4.56 times.
