Due to its excellency and versatility, many synthesis methods and conditions were developed to produce HKUST-1 ([Cu(BTC)(HO)]). However, the diversity of HKUST-1 was actually generated both in terms of characteristics and morphologies. Hence, the consistency of HKUST-1 characteristics and morphologies needs to be maintained. The statistical analysis and optimization provide features to determine the best synthesis condition. Here, a room-temperature coordination modulation method was proposed to maintain the morphology of HKUST-1 while reducing energy consumption. In addition, response surface methodology (RSM) was used to demonstrate the statistical analysis and optimization of the synthesis of HKUST-1. The molar ratio of ligand to metal, reaction time, and acetic acid concentration were studied to determine their effects on HKUST-1. The optimum HKUST-1 was obtained by the synthesis with a molar ratio of ligand to metal of 0.4703 for 27.2 h using 5% / acetic acid concentration. The statistical analysis performed a good agreement with the experimental data and showed the significance of three desired parameters on HKUST-1. The optimum HKUST-1 had the adsorption capacity of 1005.22 mg/g with a removal efficiency of 92.31% towards CV dye. It could be reused up to 5 cycles with insignificant decrease in performance.
由于其优异的性能和多功能性，开发了许多合成方法和条件来制备 HKUST-1([Cu(BTC)(HO)] )。然而，HKUST-1 的多样性实际上是在特性和形态方面产生的。因此，需要保持 HKUST-1 特性和形态的一致性。统计分析和优化提供了确定最佳合成条件的特征。在这里，提出了一种室温配位调制方法，以在降低能耗的同时保持 HKUST-1 的形态。此外，还使用响应面法 (RSM) 来展示 HKUST-1 合成的统计分析和优化。研究了配体与金属的摩尔比、反应时间和乙酸浓度，以确定它们对 HKUST-1 的影响。通过在摩尔比为 0.4703 的情况下反应 27.2 小时，使用 5%/乙酸浓度合成得到了最佳的 HKUST-1。统计分析与实验数据吻合良好，表明三个理想参数对 HKUST-1 的重要性。最佳的 HKUST-1 对 CV 染料的吸附容量为 1005.22mg/g，去除效率为 92.31%。它可以重复使用 5 次，性能下降不明显。
