Description

General description

Nickel (II) sulfate hexahydrate (NiSO₄·6H₂O), commonly called retgersite, is a naturally occurring enantiomorphic mineral. It crystallizes in the monoclinic space group C2/c. Crystal structure of its various polymorphic forms have been investigated. The chiral nickel sulfate hexahydrate has been reported to induce asymmetric autocatalysis. The thermal degradation behavior of nickel(II) sulfate(VI) hexahydrate in air and helium atmosphere has been studied using thermogravimetry (TG) and X-ray powder diffraction (XRD).

Application

• Improvement of ion chromatography with ultraviolet photometric detection and comparison with conductivity detection for the determination of serum cations.: This study explores advanced ion chromatography techniques for analyzing serum cations, where Nickel(II) sulfate hexahydrate may be used as a standard or in method development. The research compares ultraviolet photometric detection with conductivity detection, enhancing analytical methods for precise cation analysis in various samples, which can be crucial for environmental and clinical chemistry (Shintani H, 1985).
