Complexes of Nickel(II) with [(Prop-2-en(yn)-1-yl)oxy]ethanimidothioate and Their Applications
摘要
Abstract
The reactions of nickel(II) with (S)-[(prop-2-en-1-yl)oxy]ethanimidothioate (PENT) and (S)-[(prop-2-yn-1-yl)oxy]ethanimidothioate (PINT) was studied by the extraction-photometric method. The ligands were characterized with IR and NMR spectroscopy. The influence of aqueous phase pH on the formation of Ni(II)L2 complexes and thermal decomposition were studied. The developed extraction-photometric method was applied to determine nickel in wastewater and plant samples.
