    Notes: Abstract The solid state reaction between KMnO4 and zeolite-13X at a temperature below the melting point of the salt presumably results in inclusion of manganese in the zeolite. Quantitative measurements of manganese uptake at various proportions of KMnO4 in the mixture were achieved by neutron activation analysis of the Mn-zeolite.

    Notes: Abstract Volume diffusion of I− anions in the near surface region of copper has been studied by radiotracer technique. The diffusion coefficients were determined for different I− coverages on copper employing the Gruzin method of measuring the residual activity. Diffusion annealing was carried out between 303 and 673 K. The distribution of the I− species in the diffusion-annealed sample was monitored by noting the residual activity of the specimen upon subjecting it to successive acid-etchings. The simultaneous evaporation losses from the I− deposit are reduced by securely holding the sample coupon in between two blank copper coupons using a metal clip.

    Notes: Abstract Volume diffusion coefficients of I− anions in the near surface region of silver have been determined using131I. The distribution of the labelled ions with depth is determined by acid etching and counting the residual activity. The coefficient of diffusion is determined for surface layers of three different thicknesses over the temperature range 373–823 K. The mechanism proposed assumes the dissociation of Ag+I− in surface layer and the diffusion of I− into the interstitial free space immediately beneath the surface. This process is found to be accompanied by a small negative entropy change.

    Description / Table of Contents: Abstract Поглощение избирательным обменом катионов Cs+, Ba+2 и Zn+2 из чистых растворов цеолитом-13Х подчиняется следующему порядку Q∞[Cs+]〉Q∞[Ba+2]〉Q∞[Zn+2] в то время как в случае двухкомпонентных смесей имеем Q∞[Ba+2(mix Zn+2)]〉Q∞[Ba+2(mix Cs+)]〉Q∞[Cs+(mix Zn+2)]〉Q∞[Cs+(mix Ba+2)]〉Q∞[Zn+2(mix Cs+)]〉Q∞[Zn+2(mix Ba+2)]. Поглощение Ba+2 из смеси обладает наименьшим подавляющим эффектом.
    Notes: Abstract The preferential exchange uptake of the cations Cs+, Ba2+ and Zn2+ from pure solutions by zeolite-13X follows the order Q∞ [Cs+]〉Q∞ [Ba2+]〉Q∞ [Zn2+], while in case of binary mixtures the order is Q∞ [Ba2+(Zn2+)]〉Q∞ [Ba2+(Cs+)]〉Q∞ [Cs+(Zn2+)]〉Q∞ [Cs+(Ba2+)]〉Q∞ [Zn2+(Cs+)]〉Q∞ [Zn2+(Ba2+)]. Ba2+ uptake from mixtures shows the least suppression effect.

    Notes: Abstract Competitive uptake of Cs+, Ba2+ and Zn2+ ions from aqueous medium by zeolite-3A is studied by the radiotracer technique. Suppression Cs+ uptake in presence of Ba2+ is the maximum amongst the competitive uptakes. The simultaneous uptakes of the individual cations are considered in the light of the zeolite pore size, hydration effects and mobilities of the competing cations.

    Notes: Abstract Isotherms of silver uptake by zeolite-13X from AgNO3 at temperatures /323-563 K/ around the melting point of the nitrate are reported. Measurements of silver uptake have been carried out by a neutron activation method. At temperatures below the melting point the Ag+ uptake is exchange dominant while above the melting point the exchange accompanies substantial AgNO3 inclusion. The overall process of Ag+ uptake from both the powder and the melt is endothermic within the temperature range employed.
