Synthesis of Copper(II) Trimesinate Coordination Polymer and Its Use as a Sorbent for Organic Dyes and a Precursor for Nanostructured Material

Abstract

Several important synthesis pathways for metal-organic frameworks (MOFs) were applied to determine how the synthesis methods and conditions affect the structure and adsorption capacity of the resulting samples. In the present work, three different synthesis routes were used to obtain copper trimesinate coordination polymer: Slow evaporation (A), solvothermal synthesis using a polyethylene glycol (PEG-1500) modulator (B), and green synthesis in water (C). This MOF was characterized by elemental analysis, infrared spectrometry, X-ray diffraction, scanning electron microscopy, thermogravimetry and volumetric nitrogen adsorption/desorption. The samples have permanent porosity and a microporous structure with a large surface area corresponding to the adsorption type I. The obtained MOF was tested as a sorbent to remove organic dyes methylene blue (МВ), Congo red (CR) and methyl violet (MV) as examples. Dye adsorption followed pseudo-first-order kinetics. The equilibrium data were fitted to the Langmuir and Freundlich isotherm models, and the isotherm constants were determined. Thermodynamic parameters, such as changes in the free energy of adsorption (∆G0), enthalpy (∆H0), and entropy (∆S0), were calculated. Thermolysis of copper trimesinate leads to the formation of carbon materials Cu@C with a high purity.

Metal Organic Frameworks to Remove Arsenic Adsorption from Wastewater

“…However, this is a tedious and time-consuming technique. Sometimes different combinations of solvents are also used to increase the solubility and rate of the reaction [22,86,119]. In solvothermal synthesis, the reactions are performed in closed vessels or Teflon-lined autoclaves at temperatures beyond the boiling point of the solvent [111].…”

Highly effective selectively removal of carcinogenic dyes and iodine adsorption and release via a metal–organic framework based on multiple helical chains

“…Eventually, the Q m of Cu-BCPPy to SD III and DB 38 are calculated to be 557 and 164 mgÁg À1 , respectively, which is higher than many reported copperbased MOF materials (Table 1). [43,[46][47][48][49][50][51][52][53][54][55][56][57] As has been stated above, Cu-BCPPy provides a probability of selectively removing large-size carcinogenic dyes.…”

Directionally-Grown Carboxymethyl Cellulose/Reduced Graphene Oxide Aerogel with Excellent Structure Stability and Adsorption Capacity

“…Therefore, such contaminants need to be removed with low-cost competent techniques in order to use the water for drinking or other purposes, which is growing to be a foremost challenge currently. Adsorption [ 5 , 6 , 7 ], an economic, efficient and eco-friendly technology, has the characteristics of clear principle and convenient industrial application.…”
