Item Uso do planejamento brereton para confecção de polímeros e biopolímeros na remoção de azul de metileno em meio aquoso com detecção no UV-VIS(2019) Diniz, Amanda Caroline de Oliveira; Nascimento, Elaine Cristina Lima do; http://lattes.cnpq.br/1224379023006746; http://lattes.cnpq.br/3991664513262160Pollution of water resources is a serious problem to be dealt with, as it comes from synthetic tailings that are thrown into bodies of water that damage all fauna and flora in the environmental compartment. Thus, research has been emerging to reduce and / or remove toxic products, heavy metals and effluent dyes in aquatic systems. As a result, there is a range of developed materials acting as adsorbents or biosorbents for the treatment of the water system. As the objective of this work make films of different matrices (starch and PVC) with or without reinforcement (sisal fiber) to obtain the best removal rate. Thus, the Brereton 54 planning was used to make the films, which took into account several factors such as matrix, reinforcement, plasticizer and solvent, where it generated polymers (PVC), biopolymers (maize starch), biocomposites (maize and sisal fiber powder), composites (PVC and sisal) and polymeric blends (cornstarch and PVC with or without sisal). These were made according to the planning tests, using the 6-film solvent evaporation technique where they were physically evaluated by visual inspection and UV-VIS spectrometry. As a result, in general, the films presented few uniform, resistant and without bubbles, highlighting that the E4BC10 biocomposite and E1CO10 composite films showed higher removal rate of me.
