Abstract
Herein, we report study about adsorption kinetics of rhodamine B onto metal organic framework containing cobalt (CoOF). The CoOF can be successfully produced from the reused waste–organic ligands and solvents. The as-prepared material was carbonized and purified prior to testing. The adsorbent was characterized with scanning electron microscopy, Fourier transform infrared spectrophotometer, X-ray diffractometer, thermogravimetric analysis, Raman spectroscope, and N2 adsorption/desorption isotherms. The kinetics of dye adsorption onto structure was examined with the UV–Vis spectrophotometer. Various physiochemical parameters such as initial dye concentration, pH of dye solution, and temperature were investigated in an adsorption technique. The adsorption uptake was found to increase with increase in initial dye concentration. An increase in adsorption capacity was noticed when the solution was changed to basic, optimum conditions obtained at pH 7. The results indicate that along with an increase in the tem...
