15. Quantificação de antimônio em garrafas de politereftalato de etileno (PET) brasileiras por fluorescência de raios-X e avaliação quimiométrica para verificar a presença de pet reciclado através do teor de ferro
Antimony is a common catalyst in the synthesis of polyethylene terephthalate used for food-grade bottles manufacturing. However, antimony residues in final products are transferred to juices, soft drinks or water. The literature reports mentions of toxicity associated to antimony. In this work, a green, fast and direct method to quantify antimony, sulfur, ir

16. Efeitos da história térmica nas propriedades do polímero pet: um experimento para ensino de análise térmica
Polyethilenetherephtalate (PET) is commonly used in manufacturing of beverage bottles representing a didactic appeal in thermal analysis education due to its presence in the student's day life. Additionally such polymer presents well defined thermal analytical curves and a well known thermal behavior. TGA curve is used to present the thermal stability. The t

17. AnÃlise da utilizaÃÃo de gargalos e fios de garrada pet como enchimento de torres de resfriamento
In some industrial processes, as well as in air conditioning processes, there is the need for cooling of equipments that generate heat during his operation. Usually, the fluid utilized to dissipate that generated heat is the water, due to its physical characteristics (high heat capacity, low viscosity, high thermal conductivity and high density). Besides its

18. Hidrólise parcial da superfície do polyethylene terephthalate (PET): transformando um rejeito em um material de troca catiônica para aplicação ambiental
In this work it is proposed a simple and versatile undergraduate chemical experiment in polymer and environmental technology based on the process of polyethylene terephthalate (PET) hydrolysis. Polyethylene terephthalate from post-consume bottles is submitted to a controlled partial hydrolysis which allows the students to follow the reaction by a simple proc

19. Biodegradação de polietileno tereftalato (PET) por fungos ligninoliticos / Biodegradation of polyethylene tereftalate by ligninolytic fungi
In 1977, polyethylene terephthalate (PET), a plastic derived from petroleum, started to be used as raw material for packaging material and engineering plastics. However, under an environmental point of view, the use of plastics is considered problematic because of their high durability and high volume when present in domestic and industrial solid wastes. Thi
