AB  - Elderberry (Sambucus nigra) pith was modified with polyethyleneimine (PEI) in order to improve the adsorption properties. Characterization of both dried Sambucus nigra pith (DSNP) and amino modification of elderberry pith with branched PEI (PEI/DSNP) was performed by: Fourier-transform infrared spectroscopy (FTIR), optical microscopy, and porosity determination. The amine and ester number, as well as acid value, were determined on DSNP and PEI/DSNP samples using standard volumetric methods. The samples were used as adsorbents for Pb2+ ions from an aqueous solution in a batch system. The obtained results were fitted using suitable equilibrium isotherm and kinetic models. The maximum adsorption capacity for Pb2+ ions on DSNP and aminаted sample, obtained using Langmuir adsorption isotherm at 298 K, are 18.9 and 47.8 mg g-1, respectively. Based on the kinetic studies, the adsorption process follows the pseudo second-order model. Thermodynamic parameters showed that the adsorption process is endothermic and spontaneous. In general, the overall adsorption process was improved by modifying starting material with branched PEI modifier by introducing large numbers of amino functionalities having high affinity to cations.

AB  - The present work reports the commercialization of a recycling process of spent acid from filament
tungsten wire plant to recover molybdenum (VI)-oxide and further utilizing this product for alloying
cast iron. First part of the process consists of ammonia gas neutralization of spent acid containing
molybdenum, crystallization and filtration of ammonium molybdate, drying and roasting to produce
a commercial grade molybdic-trioxide powder (molybdenum mass fraction 59.2 mas%). Second
part of the process consists of grey cast alloying with MoO3 in inducing furnace. Final product was
hardened iron alloy with high yield of molybdenum recovery (up to 86 %).
