Descrição geral

Zinc sulfate heptahydrate has various industrial applications. It is widely employed as an electrolyte for zinc electroplating and for the storage of solar energy in various solar appliances. Its crystals exhibit diamagnetism.

Aplicação

Zinc sulfate heptahydrate may be used in the following studies:
  • To compose electrolyte for the electrodeposition of Cu-Zn-Sn precursors on Mo-coated glass substrates.
  • Preparation of internal standard (IS) working solution for use in liquid chromatography (LC) coupled with mass spectrometry (MS) analysis.
  • Titrimetric estimation of holmium content in the holmium loaded poly(L-lactic acid) films and microspheres.

Holmium-loaded PLLA microspheres are useful systems in radioembolization therapy of liver metastases because of their low density, biodegradability and favourable radiation characteristics. Neutron activated Ho-loaded microspheres showed a surprisingly low release of the relatively small holmium complex. In this paper
