| Abstract: | K2Zn3Fe(CN)6]2, 9 H2O crystallises in the rhombic system. Lattice parameters are a = 12.941 Å, α = 58.01°. Thermal behaviour of this compound, studied by differential thermal analysis, thermogravimetric analysis and X-ray diffractometry, permitted the determination of the conditions for activation. The adsorption isotherms confirm the zeolitic character of this iron cyanide with a relative important adsorption capacity. The water is released in two steps with a contraction of the lattice. |
