for two hours on Nuova-II stir plate. After this dilutions
(300ml distilled H20) were made for filtration. It was
carried out through precision suction pump.
Finally, the filtrate was removed and concentrated to
the density between 1.48-1.51 g/cm3
and it was
crystallized in the crystallization dish at room
temperature 27°C. Crystals were analysed for Zinc
contents on Atomic Absorption Spectrophotometer.
Small, orthorhombic and shiny crystals were obtained.
Physical and chemical tests were performed to ensure
that the recovered chemi
