Arsenic(V) removal with polymer inclusion membranes from sulfuric acid media using DBBP as carrier.

Polymer inclusion membranes (PIMs) based on cellulose triacetate (CTA) and dibutyl butyl phosphonate (DBBP) were tested for arsenic(V) separation from H2SO4 for its recovery from copper electrolytes. Solvent extraction experiments allowed the determination of the As(V)-DBBP and H2SO4-DBBP complexes formed in the organic phase. Application of a transient model to membrane transport experiments in solutions containing only arsenic or H2SO4 indicated that it occurred under a kinetically controlled regime by formation of H3AsO4[DBBP]2 and H2SO4[DBBP] species, respectively.

Experience with GyneFIX insertions in Spain: favorable acceptance of the intrauterine contraceptive implant with some limitations.

This study evaluates the incidents associated with GyneFIX insertion and first-year expulsion and continuity rates within the usual intrauterine contraceptive practice of a working group of Spanish professionals (GESEG), formed specifically with this aim. It is a prospective, multicenter, observational study of GyneFIX insertion in 1684 women. Data were prospectively collected on a structured form and processed centrally.
