“…Table 3 lists the values of the decay constant of the absorbance, calculated from the slope of the line obtained in each test with the catalyst and the coefficient of determination of the curves (R 2 ). The HAP synthesized by the HP method has lower efficiency than the HAP synthesized by the CP method, mainly due to the lower surface area and smaller pore volume, according to sorption measurements (Lindino et al, 2016).…”

Fish farming is becoming a highly profitable economic activity and the rearing of fingerlings involves the practice of sex reversal for the production of species (male) using the hormone 17α-methyltestosterone (MT). This study analyzed the methodology for degradation of the hormone through solar and ultraviolet radiation using hydroxyapatite (HAP) as heterogeneous catalyst, synthesized by two different methods, with and without doping with nickel and copper. The results showed that MT hormone is degraded by ultraviolet or solar radiation, and accelerated in the presence of the HAP catalyst. In the presence of Fe (III) in the medium, the degradation rate of the hormone decreases. The method of HAP synthesis influences the degradation efficiency.Keywords: fish fry, hormone, fish-farming. Degradação de 17α-metiltestosterona com catalisador hidroxiapatita RESUMOA piscicultura tem se tornado uma atividade econômica altamente rentável e, para isto, a criação de alevinos adota a prática da reversão sexual para produção de espécies (macho) por meio do hormônio 17α-metiltestosterona (MT). Este trabalho desenvolveu metodologia para a degradação deste hormônio, por meio de radiação solar e ultravioleta utilizando catalisador heterogêneo hidroxiapatita (HAP) sintetizada por dois métodos diferentes, com e sem dopagem com níquel e cobre. Os resultados mostraram que o hormônio MT é degradado pela radiação ultravioleta ou solar, sendo acelerado na presença do catalisador HAP e a presença de Fe(III) no meio diminui a velocidade de degradação do hormônio. O método de síntese da HAP influencia na eficiência da degradação.Palavras-chave: alevinos, hormônio, piscicultura.

This review focuses on a reasoned search for articles to treat contaminated water using hydroxyapatite (HAp)-based compounds. In addition, the fundamentals of heterogeneous photocatalysis were considered, combined with parameters that affect the pollutants’ degradation using hydroxyapatite-based photocatalyst design and strategies of this photocatalyst, and the challenges of and perspectives on the development of these materials. Many critical applications have been analyzed to degrade dyes, drugs, and pesticides using HAp-based photocatalysts. This systematic review highlights the recent state-of-the-art advances that enable new paths and good-quality preparations of HAp-derived photocatalysts for photocatalysis.
