Adsorptive uptake of congo red (CR) dye from water by a Ni(II) coordination compound containing carboxylate and N-donor ligands, formulated as [Ni(TDPH)(BPY)] 1, is herein reported (4,4-bipyridine= BPY; 3,3-thiodipropionate= TDPH). Characterization of the compound was done by Scanning Electron microscopy (SEM), Thermogravimetric analysis (TGA), Infrared spectroscopy (FTIR), and X-ray diffraction (XRD) analysis. Experimental data were subjected to isotherm and kinetics studies, an R2 value of 0.9953 was obtained for the Langmuir isotherm while the pseudo-second-order model was observed to be best fit for the experimental data with a correlation coefficient value of 0.9918.
