    Annotation© 2016, National Museum Prague. All rights reserved. Laumontite and heulandite-Ca were found in the cracks and cavities of Permian basalt (Malužiná Formation, Ip oltica Group of the Hronicum Unit), in the eastern part of the Kozie Chrbty Mts., at Spišská Teplica Štefánikova and Lučivná Lopušná Dolina localities. Laumontite has a relatively monotonous chemical composition, only K content reaches up to 0.75 apfu. Average crystallochemical formula of laumontite (both occurrences) is (K 0.41 Na 0.06 Ca 3.61 ) Σ4.08 [Si 16.03 A l7.54 ] Σ23.56 O 48 ·18H 2 O, Si/Al ratio 2.13. Main diffraction maxima d(I) of laumontite are 9.461(100), 6.844(44), 4.157(48), 3.508(33), 3.272(22), unit cell parameters: a = 14.738(1) Å, b = 13.087(1) Å, c = 7.554(1) Å, β = 111.84°, V = 1352.3 Å3. Ca is dominant component in heulandite-Ca from the Štefánikova occurrence (2.18 2.69 apfu), from other admixtures, significantly increased is K content (1.30 2.35 apfu). Less important are Ba (0.05 0.7 apfu) and Sr (0.23 0.60 apfu), Na content reached up to 0.26 apfu. Average chemical composition of studied heulandite-Ca corresponds to formula (K 1.79 Na 0.16 Ca 2.39 Ba 0.38 Sr 0.39 Fe 0.13 ) Σ5.24 [Si 26 .82Al 8.94 ] Σ35.76 O 72 ·24H 2 O, Si/Al ratio 3.00. Its main diffraction maxima d(I) are 8.954(100), 4.650(17), 3.976(18), 3.897(18), 2.973(37), unit cell parameters: a = 17.786(1) Å, b = 17.930(1) Å, c = 7.4338(1) Å, β = 115.93°, V = 2131.9 Å3. Zeolites probably originated during the Alpine orogeny, at the reduced p-T conditions after a peak of the prehnite-pumpellyite facies of basalt metamorphosis. The minimum estimated conditions of their origin are T ~ 210 °C and p 2.1 2.4 kbar, corresponding to the burial depth of Hronicum basalts around 7 km, in the time of zeolites formation.

    AnnotationThe removal of Pb(II) ions from synthetically prepared solutions by different low-cost adsorbents (waste polyurethane foam, Slovak bentonite, and zeolite) was investigated. The adsorption experiments were carried out under a batch process with the concentration of Pb(II) ions, amount of adsorbent, pH, and time as the variables. Adsorption was strongly dependent on the pH of the medium, with the uptake of Pb(II) increasing as the pH increased from pH 1.5 to 5.0, after which the experiments could not be continued due to the decreasing solubility of Pb(II). The adsorption was very fast at low coverage, and equilibrium was approached within 60min. The results best fitted the second-order kinetic model, with the rate constant in the range of 3.0x10(-2)-2.9g/mgmin. The Langmuir maximum adsorption capacity of the waste polyurethane foam, zeolite, and bentonite was found to be 14.1, 43.9, and 48.1mg/g, respectively.
