A series of new Ni(II) dithiocarbamate compounds of the composition [NiX(cetdtc)(PR3)](X = Cl, Br, I, NCS; cetdtc = cyclohexylethyldithiocarbamate; R = phenyl, n-butyl) has been synthesized. All the isolated complexes have been characterized by elemental analysis, IR and UV/VIS spectroscopy, 31P{1H}-NMR spectroscopy, thermal analysis magnetochemical and conductivity measurements. On the basis of the results of the physico-chemical study, all complexes are diamagnetic, non-electrolytes with a square-planar NiS2PX chromophore.

This paper describes the physico-chemical study of the adsorption of dysprosium (Dy3+) in aqueous solution onto two types of activated carbons synthesized from spent coffee ground. KOH activated carbon is a microporous material with a specific BET surface area of 2330 m2·g-1 and pores with a diameter of 3.2 nm. Carbon activated with water vapor and N2 is a solid mesoporous, with pores of 5.7 nm in diameter and a specific surface of 982 m2·g-1. A significant dependence of the adsorption capacity on the solution pH was found, while it does not depend significantly neither on the dysprosium concentration nor on the temperature. A maximum adsorption capacity of 31.26 mg·g-1 and 33.52 mg·g-1 for the chemically and physically activated carbons, respectively, were found. In both cases, the results obtained from adsorption isotherms and kinetic study were better fit to a Langmuir model and a pseudo-second-order kinetics. In addition, thermodynamic results indicate that dysprosium adsorption onto both activated carbons is an exothermic, spontaneous and favorable process.
