A Co 2+ ion-selective membrane sensor has been fabricated in a poly(vinyl chloride) matrix based on a recently synthesized 3,3′-(dodecylazanediyl)bis(N-(2-(2-aminoethylamino)ethyl)propanamide) (DAEP) as a neutral carrier, sodium tetraphenylborate (NaTPB) as an anionic excluder, and dioctylphthalate (DOP) as a solvent mediator. The electrode exhibits a Nernstian response over a wide concentration range [(6.58 • 10 -7 to 1.0 • 10 -1 ) M] between pH 2.5 and 8.5, and the limit of detection is 6.82 • 10 -8 M. The response time of the sensor is about 5 s, and it can be used over a period of 5 months without any divergence in potential. The proposed membrane sensor revealed good selectivity for Co 2+ over a wide variety of other metal ions. The electrode has been used as an indicator electrode in the potentiometric titration of Co 2+ with ethylenediaminetetraacetic acid (EDTA) and the direct determination of Co 2+ in wastewater from the electroplating industry.

“…These compounds were dissolved in 3 ml of THF to obtain the yellow oily concentrate mixture. A Pyrex glass tube (3 mm ID and 5 mm length) was applied to prepare the membrane [40]. Two or three drops of oily concentrated mixture were poured into the Pyrex tube, so that a transparent membrane about 0.3 mm thick was formed.…”

Mn(II), Co(II), Ni(II) and Cu(II) and N,N-bis(3,5-di-tert-butylsalicyidene)-2,2-dimethyle-1,3-diaminopropane complexes have been synthesized in Y zeolite cavity by the reaction of ion-exchanged metal ions with the flexible ligand molecules. The host-guest materials obtained have been characterized by elemental analysis, XRD, surface area, pore volume, TGA, FT-IR and UV-Vis techniques. Analysis of data indicates that formation of complexes in the pores Y zeolite without affecting the zeolite framework structure. Also, we report the oxidation of cyclohexanol catalyzed by host-guest catalyst with tert-buthyl hydrogen peroxide as oxygen donor. The activity of benzyl alcohol oxidation decreases in the series-[Co(L)]/NaY > [Cu(L)]/NaY > [Mn(L)]/NaY > [Ni(L)]/NaY and the percent of product completely depend to catalyst. Zeolite complexes are stable enough to be reused and are suitable to be utilized as partial oxidation catalysts.
