摘要:

A new analytical method using the reagent di-2-pyridyl ketone benzoylhydrazone (DPKBH) as a colorimetric chelating agent for the spectrophotometric determination of Ni(II) in natural water samples wasestablished. This method involves a liquid-liquid extraction and was developed for determination of trace amounts of Ni(II).
