Copper(II) and nickel(II) complexes of 14-membered hexaazamacrocyclic ligand with C-methyl substituent have been synthesized by one-pot reaction and characterized by elemental analyses, FT-IR, electronic spectra, and LC-MS. Complex types are [Cu(C18H42N6)(ClO4)2] (1), [Ni(C18H42N6)](ClO4)2 (2), and [Cu(C22H50N6)(ClO4)2] (3). The results of spectroscopic techniques indicated that both complexes 1 and 3 containing...

This work investigates the comparative adsorptive removal of Ni (II) ions from aqueous solution using coconut shell and banana peel. Optimum conditions for adsorption were determined by experimental design, while Analysis of Variance (ANOVA) and BonferroniHolm Posthoc significance statistical tests on operational parameters were also conducted. The parametric effect of...

Model adsorpsi senyawa koordinasi Ni2+-H2O, Ni2+-NH3, Nit+-EDTA dan Nit+-CN pada permukaan alumina digambarkan berdasarkan variasi variabelnya, yaitu pH, spesies ligan dan alumina serta kuat ion. Metode adsorpsi yang digunakan adalah pengguncangan. Pengujian juga dilakukan secara visual dengan menggunakan Scanning Electron Microscope (SEM).
Alumina yang digunakan berasal dari AICI3 dengan variasi suhu...
