Synthesis and Characterization of Potassium Manganese Nickel Sulphate Hexahydrate: A Potential UV Filter

摘要

Single crystals of potassium manganese nickel sulphate hexahydrate were crystallized by the slow evaporation technique from aqueous solutions. Crystals obtained have been analyzed by powder XRD, single crystal XRD, SEM-EDX, FTIR, UV transmission, atomic absorption spectral analysis and TG-DTA. The lattice parameters were calculated from the XRD data. Atomic absorption spectral analysis showed that the Mn atoms were present in the mixed crystals and it is confirmed by EDX. Scanning electron microscopic studies used to understand the morphology of the calculi. The thermal analysis, TGA and DTA showed that the mixed crystals have higher thermal stability than the potassium nickel sulphate hexahydrate crystals. UV-visible spectral studies confirmed that the grown crystal is transmissive in the ultraviolet region.
