Feasibility of Forward Osmosis to Recover Textile Dyes Using Single Salts and Multicomponent Draw Solutions. Membranes 2023, 13, 911. https://doi.org/10.3390/ membranes13120911 This dataset includes the results of the test perfomed and presented in the paper. File and folder structure Results_ Feasibility of Forward Osmosis to Recover Textile Dyes_Membranes.ods has 4 folders. Each folder presents the result obtained in the dye concentration study with a forward osmosis membrane. Folder 1: Draw solution selection This folder presents the test performed to select the suitable draw solution. The membrane test were permormed with three different solutions, NaCl (1M), MgCl2 (1M) and Na2SO4 (1M). Folder 2: Test_with_NaCl(0.5M;1.5M;2M;3M) This folder presents the characterization of the cellulose triacetate (CTA) flat sheet forward osmosis membrane (FTSH2O) from Fluid Technology Solutions (Albany, OR, USA). The characterization was performed with NaCl at different concentration (0.5M, 1M, 2M and 3M). Folder 3: FO_test_for_dye_concentration This folder presents the three different test performed with the FO membrane for dye concentration. Test 1 was performed with NaCl (1M) as draw solution (DS) and a model solution with dye (MS1, 0.05 g/L Remazol turquoise blue G 133% + 0.5 g/L Na2SO4 + 0.5 g/L NaCL) as feed solution (FS) Test 2 was performed with Brine solution (58.44 g/L NaCl + 8.50 g/L Na2SO4 + 25.76 g/L MgCl2·6H2O) as DS and a model solution with dye (MS1, 0.05 g/L Remazol turquoise blue G 133% + 0.5 g/L Na2SO4 + 0.5 g/L NaCL) Test 3 was performed with Brine solution (58.44 g/L NaCl + 8.50 g/L Na2SO4 + 25.76 g/L MgCl2·6H2O) as DS and a model solution with dye (MS2, 0.05 g/L Sirius Blue K-CFN + 0.5 g/L Na2SO4 + 0.5 g/L NaCL) Folder 4: Characterization_FO_test_ This folder presents the characterization of the FS and DS of the tests carried out (test 1, test 2 and test 3).本数据集关联论文为Cifuentes-Cabezas, M.; García-Suarez, L.; Soler-Cabezas, J.L.; Cuartas-Uribe, B.; Álvarez-Blanco, S.; Mendoza-Roca, J.A.; Vincent-Vela, M.-C. 发表于期刊《Membranes》2023年第13卷第911篇的论文《采用单盐与多组分汲取液（Draw Solution）通过正渗透（Forward Osmosis）回收纺织染料的可行性研究》，DOI：https://doi.org/10.3390/membranes13120911。 本数据集包含该论文中呈现的所有实验测试结果。 ### 文件与文件夹结构 主文件为Results_ Feasibility of Forward Osmosis to Recover Textile Dyes_Membranes.ods，内含4个文件夹，每个文件夹对应正渗透膜用于染料浓度研究的实验结果。 #### 文件夹1：汲取液筛选 该文件夹包含用于筛选适配汲取液的实验结果。实验采用三种不同溶液：氯化钠（NaCl，1M）、氯化镁（MgCl₂，1M）与硫酸钠（Na₂SO₄，1M）开展膜测试。 #### 文件夹2：NaCl(0.5M;1.5M;2M;3M)测试实验 该文件夹包含对流体技术解决方案公司（Fluid Technology Solutions，美国俄勒冈州奥尔巴尼）生产的三醋酸纤维素（Cellulose Triacetate, CTA）平板正渗透膜（FTSH2O）的表征结果。表征实验采用不同浓度的氯化钠（0.5M、1M、2M与3M）作为测试介质。 #### 文件夹3：染料浓度正渗透测试实验 该文件夹包含三项采用正渗透膜开展的染料浓度测试实验结果： 测试1：以氯化钠（1M）作为汲取液（Draw Solution, DS），以含染料的模型溶液（MS1：0.05 g/L Remazol turquoise blue G 133% + 0.5 g/L Na₂SO₄ + 0.5 g/L NaCl）作为进料液（Feed Solution, FS）。 测试2：以盐水溶液（58.44 g/L NaCl + 8.50 g/L Na₂SO₄ + 25.76 g/L MgCl₂·6H₂O）作为汲取液，以含染料的模型溶液（MS1：0.05 g/L Remazol turquoise blue G 133% + 0.5 g/L Na₂SO₄ + 0.5 g/L NaCl）作为进料液。 测试3：以盐水溶液（58.44 g/L NaCl + 8.50 g/L Na₂SO₄ + 25.76 g/L MgCl₂·6H₂O）作为汲取液，以含染料的模型溶液（MS2：0.05 g/L Sirius Blue K-CFN + 0.5 g/L Na₂SO₄ + 0.5 g/L NaCl）作为进料液。 #### 文件夹4：FO测试表征实验 该文件夹包含对上述三项测试（测试1、测试2与测试3）所使用的进料液与汲取液的表征结果。
