Desenvolvimento de dispositivo caseiro para dessalinização de água salobra a partir de sementes de umbu (Spondias tuberosa Arruda Câmara)

Abstract: Recebido em 20/1/11; aceito em 20/7/11; publicado na web em 2/9/11 DEVELOPMENT OF A HOMEMADE DEVICE FOR DESALINATION OF BRACKISH WATER USING UMBU SEEDS (Spondias tuberosa Arruda Câmara). The goal of this work was to develop a homemade device to desalinate brackish water, using biological material like seeds from different plant species of the semi arid regions. Umbu seeds (Spondias tuberosa Arruda Câmara) were found to be the most appropriate material, removing a higher quantity of salt from the water compared… Show more

“…3,4 During storage, crushed seeds of umburana formed a large amount of white crystalline solid, which was mixed with the sample and was also present in the storage container lid, indicating volatilization and crystallization processes. This material was subsequently identified as coumarin (1,2-benzopyrone) by solubility and melting point tests and by infrared (IR) and mass spectra.…”

“…This process can be used in homemade devices for brackish water desalination. 3,4 Menezes et al 3,4 tested different biological materials common to the semiarid region for the sorption capacity of salts contained in brackish water. Among the materials that were considered more efficient are the umbu (Spondias tuberosa Arr.…”

“…Na sua maior parte, esses materiais são usados como alimento para animais, matérias-primas para combustão ou descartados, causando grandes problemas ambientais. Porém, esses resíduos podem ser melhores aproveitados, podendo citar algumas possíveis aplicações: matéria-prima para a produção de etanol (Bonilla-Hermosa et al, 2014), produção de carbonos ativados (Franca; Oliveira, 2009), ingredientes alimentares como antioxidantes, nutracêuticos e edulcorantes (Gonzales et al, 2015), produtos farmacêuticos, substrato em processos de fermentação (Murthy; Naidu; 2012), dessalinização de água salobra (Menezes et al, 2012), em agroquímicos, cosméticos, geo-medicina, nano-biosciência e em indústrias químicas (Kudanga et al, 2017), entre outros.…”

“…The use of this water, however, is limited by a typical problem of the water of the northeastern region: the salt content. Most of the area is located on crystalline rocks and the long underground contact between the water and this type of rock favors its salinization (MENEZES et al, 2012;SOARES et al, 2006).…”
