The sorption capacity of salt was tested for ten different biological materials. The salinity of the water was determined before and after contact with the biological material. Umbu seeds (Spondias tuberosa Arruda Câmara) were considered the most appropriate material, after treating and drying at different temperatures. The prepared material showed that the process met the Langmuir model. The maximum adsorption capacity of sodium by the material at 30, 40 and 50 °C was estimated to be: 52.6, 165 and 250 mg g−1 respectively. Thus, 1 L of brackish water with salinity between 0.6‰and 1.2‰, as the samples tested in this work, may have its sodium chloride content removed using only 1 g of the seeds treated as described in this study if the water is heated to 50 °C. The thermodynamic analysis indicated that the adsorption process is physical and exothermic and that the interactions between the biological material and sodium occurred spontaneously.Submitted by Ana Valéria de Jesus Moura (anavaleria_131@hotmail.com) on 2012-02-07T18:33:15Z No. of bitstreams: 1 __pdn.sciencedirect.com_....0-S0011916411006862-main.pdf: 256120 bytes, checksum: 95c15e917afe7943ea709c321674370e (MD5)Made available in DSpace on 2012-02-07T18:33:15Z (GMT).
