Herein, 1,4-benzenedicarboxylate (BDC) and 2-amino-1,4-benzenedicarboxylate (NH₂-BDC) as organic linkers and tetraisopropyl orthotitanate as a metal source were used to synthesize several metal-organic frameworks (MOFs) nanomaterials. Five Materials Institut Lavoisiers (MILs) as MOFs include MIL-125(Ti), NH₂-MIL-125(Ti) and three MILs with different organic linkers molar ratios (BDC/NH₂-BDC: 75/25, 50/50 and 25/75 denoted as MIL-X1, MIL-X2 and MIL-X3, respectively). The synthesized nanomaterials were used for ultrasound-aided adsorption of cationic dyes (Basic Red 46 (BR46), Basic Blue 41 (BB41) and Methylene Blue (MB)) from single and multicomponent (binary) systems. The BET, XRD, FTIR, SEM, TEM, TGA and zeta potential were used for characterizing the MILs. Dye removal followed pseudo-second order kinetics with constant rate of 0.20833, 0.00481 and 0.00051 mg/g min for BR46, BB41 and MB, respectively. In addition dye adsorption obeyed the Langmuir isotherm model and the maximum dye adsorption capacity for BR46, BB41 and MB was 1250, 1428 and 833 mg/g, respectively. The synthesized MIL showed high reusability and stability over three cycles. The adsorption thermodynamics data presented that dye removal was a spontaneous, endothermic and physical reaction. The free Gibbs energy for dye removal by the NH₂-MIL-125(Ti) at 308K was -19.424, -15.721 and -17.413 kJ/mol for BR46, BB41 and MB, respectively.

在此，使用1,4-苯二甲酸（BDC）和2-氨基-1,4-苯二甲酸（NH ₂ -BDC）作为有机连接物，并使用原钛酸四异丙酯作为金属源来合成几种金属有机骨架（MOFs）纳米材料。作为MOF的五种材料研究所（MIL）包括MIL-125（Ti），NH ₂ -MIL-125（Ti）和三种具有不同有机连接基摩尔比（BDC / NH ₂）的MIL-BDC：分别表示为MIL-X1，MIL-X2和MIL-X3的75 / 25、50 / 50和25/75）。合成的纳米材料用于从单组分和多组分（二元）体系中超声辅助吸附阳离子染料（碱性红46（BR46），碱性蓝41（BB41）和亚甲基蓝（MB））。BET，XRD，FTIR，SEM，TEM，TGA和zeta电位用于表征MIL。BR46，BB41和MB的染料去除遵循伪二级动力学，恒定速率分别为0.20833、0.00481和0.00051 mg / g min。此外，染料吸附遵循Langmuir等温模型，BR46，BB41和MB的最大染料吸附容量分别为1250、1428和833 mg / g。合成的MIL在三个周期内显示出很高的可重用性和稳定性。吸附热力学数据表明，染料的去除是自发的，吸热和物理反应。NH去除染料的自由吉布斯能量对于BR46，BB41和MB，在308K时的₂ -MIL-125（Ti）分别为-19.424，-15.721和-17.413 kJ / mol。
