The electrochemical detection of ciprofloxacin (CIP) using copper metal organic framework (Cu BTC) is reported. The glassy carbon electrode was used as a base electrode which was further modified with Cu BTC and differential pulse voltammetry technique was adopted for electrosensing. Under optimized conditions, a linear response for CIP was obtained in concentration range from 1×10−8 to 20×10−6 mol L−1 with a limit of detection of 0.47×10−9 mol L−1. Moreover, the proposed electrosensor showed acceptable reproducibility with 2.39 % relative standard deviation. Determination of CIP in tap water samples showed good recovery in range of 94.6–108 %.

“…In addition, the bands at 500 and 664 cm -1 were related to the stretching modes of Cu-O coordination bond, and Cu2O bonding, respectively [46,50,51]. Two bands observed at 741 and 826 cm -1 were assigned to out-of-plane ring C−H bending [19,46]. Moreover, bands at 1003 and 1611 cm -1 were related to stretching modes of C=C bonding in the structure of Cu-BTC NPs [46,52].…”

Cu-based nanostructures are a well-known class of antibacterial nanomaterials with broad antibacterial properties. In this study, a facile and one-pot solvosonication process is introduced to synthesize Cu-BTC/graphene oxide nanocomposites with controlled morphological and structural properties. The size range of synthesized Cu-BTC nanoparticles is controlled through the synthesis process by adjusting the content of graphene oxide nanosheets in the synthesis precursor solution. A wide range of sizes and morphologies are achieved via this strategy and the size range of Cu-BTC nanoparticles from 30-40 nm to 15-20 nm are obtained by increasing the content of graphene oxide in the precursor solution from 0.005 to 0.15 mg/ml. We believe an increase in the number of available sites on the basal plane of graphene oxide for the nucleation of Cu-BTC nanocrystals is the main reason for the smaller size range of Cu-BTC nanoparticles with higher concentrations of graphene oxide in the precursor solution.Moreover, the antibacterial activities of the Cu-BTC/graphene oxide nanocomposites are also

“…it will differ in physical and chemical characteristics. As evidence, HKUST-1 has various morphologies due to different synthesis conditions, such as octahedrons [14], cubes [13], cuboctahedrons [40], hexagonal polyhedrons [23], rod-like shapes [21], irregular-layered sheets [43], agglomerates [11], or even monoliths [12]. This uncertain morphology can be overcome by the coordination modulation method using additional modulators or chemicals to maintain crystal growth of HKUST-1, such as acetic acid [44,45], nitric acid [46,47], sodium bicarbonate [13,48], sodium acetate, sodium formate, and triethylamine [49].…”

Due to its excellency and versatility, many synthesis methods and conditions were developed to produce HKUST-1 ([Cu3(BTC)2(H2O)3]n). 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% v/v 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.
