In this study, copper-benzene tricarboxylic (Cu-BTC), or better known as HKUST-1, was successfully synthesized using the solvothermal method in a solvent mixture of water, ethanol and N,N-Dimethylformamide (DMF). The mother liquor from the first synthesis was reused as a solvent for the subsequent HKUST-1 synthesis for up to four repetitions, cutting back the use of fresh solvent as much as 37 %. The fifth material obtained showed similar thermal stability and specific surface area to that of the first one, even though the surface morphology turned from an octahedral shape in the first material to an irregular shape in the fifth material. The results of the adsorption study on Cr(VI) in aqueous media showed that the first and the fifth materials had adsorption capacities of 91 mg/g and 100 mg/g respectively. Both adsorbents followed a pseudo-second order adsorption kinetics with a Langmuir isothermal adsorption model.

在这项研究中，使用溶剂热法在水，乙醇和N，N的溶剂混合物中成功合成了铜-苯三羧酸（Cu-BTC），或更好地称为HKUST-1。-二甲基甲酰胺（DMF）。第一次合成的母液可重复用作溶剂，用于随后的HKUST-1合成（最多重复四次），从而使新鲜溶剂的使用量减少了37％。即使表面形态从第一材料中的八面体形状变为第五材料中的不规则形状，所获得的第五种材料也显示出与第一种材料相似的热稳定性和比表面积。在水介质中对Cr（VI）的吸附研究结果表明，第一种和第五种材料的吸附容量分别为91 mg / g和100 mg / g。两种吸附剂均采用Langmuir等温吸附模型遵循拟二级反应动力学。
