Kawakib A. Aziz,Thana Y. Yousif +1 more
TL;DR: In this paper , the preparation of new metal complexes via reaction of two anthraquinone ligands with Mn(II), Co(II) and Ni(III), Ni(I), Cu(I) and Zn(II).
Flotation-Spectrophotometric Investigations on an Ion- Association System Containing Zirconium (IV)
TL;DR: In this article, the optimum conditions for zirconium (IV) flotation and spectrophotometric determination as an ion-association compl ex were found: flotation solvent (chloroform), shak ing time (2 min), pH (6.0-6.1), acetate buffer, sequence of their addition, dissolution solvent for the floated compound (dimethylsulphoxide) and its volume (4 mL).
