Lead, copper, cobalt, nickel, iron and zinc ions form monocitrate complexes (negative charge) in citrate solution which is absorbed on the citrate form of anion-exchange resins (citrate as counter ion) y exchange of citrate ion with citrate complexes. These are subsequently recovered from the resin by 0.5M ammonium citrate eluent at pH 2.0. Under optimized conditions, quantitative recovery ...

In the title compound, C(29)H(21)BrF(2)O(3), the dihedral angles between the central anisole ring and the pendant fluoro-benzene rings are 48.86 (19) and 31.89 (18)°. The dihedral angle between the anisole ring and the 1-bromo-2-meth-oxy-benzene ring linked via the enone bridge is 82.95 (17)°. In the crystal, C-H⋯O hydrogen bonds link the mol-ecules into C(11) chains propagating along [010].

In this research the  ion exchange potential of natrolite towards K+, Tl+, Cs+, Ca+2, Ni+2, Cu2+, and Co2+ in their melted salts was investigated. The effect of temperature, reaction time and zeolite to salt ratio on the exchange relation was studied. The exchange of Ca2+, Ni2+, Cu2+, and Co2+ was negligible and was equal to 2.59, 6.29, 3.14 and 5.04 percent respectively whereas the exchange of...
