Eletrodo íon-seletivo para determinação potenciométrica de alumínio(III) em meio de fluoreto

The construction and analytical evaluation of a coated graphite Al(III) ion-selective electrode, based on the ionic pair formed between the Al(F)n3-n anion and tricaprylylmethylammonium cation (Aliquat 336S) incorporated on a poly(vinylchloride) (PVC) matrix membrane are described. A thin membrane film of this ionic pair and dibutylphthalate (DBPh) in PVC was deposited directly on a cylindric graphite rod (2 cm length x 0.5 cm diameter) attached to the end of a glass tube using epoxy resin. The membrane solution was prepared by dissolving 40% (m/m) of PVC in 10 mL of tetrahydrofuran following addition of 45% (m/m) of DBPh and 15% (m/m) of the ionic pair. The effect of membrane composition, fluoride concentration, and several concomitants as potential interferences on the electrode response were investigated. The aluminium(III) ion-selective electrode showed a linear response ranging from 1.4 x 10-4 to 1.0 x 10-2 mol L-1, a detection limit of 4.0 x 10-5 mol L-1, aslope of -54.3±0.2mV dec-1 and a lifetime of more than 1 year (over 3000 determinations for each membrane). The slope indicates that the ion-selective electrode responds preferentially to the Al(F)4- species. Application of this electrode for the aluminium(III) determination in stomach anti-acid samples is reported.

Emprego de compostos organometálicos mononucleares de paládio(II) na ativação de macrófagos peritoneais de camundongos

The immune responses are mediated by a variety of cells that, when activated, produce a number of molecules. Macrophages are the first cells to take part in the immune response releasing many compounds in the extracellular environment such as H2O2. Taking into account this aspect we evaluated the activation of an immunological system, in vitro, by determining the H2O2 released in cultures of peritoneal macrophage cells from Swiss mice in the presence of organopalladated compounds of the type [Pd(dmba)(X)(dppp)], dmba = N,N-dimethylbenzylamine, dppp = 1,3-bis(diphenylphosphine)propane, X = Cl, N3, NCO, NCS. An excellent activation of macrophages by the [Pd(dmba)(X)(dppp)] compounds was observed and the influence of the X ligand on the immune response could be verified.
