Abstract

 

The possibility of formatting a colored complex between Ni2+ ions and 4-Hydroxy-3-[[(2-hydroxy phenyl) methylene] amino] benzene Sulphonic Acid (HPHMAB) was studied by spectrophotometric method for determination of Nickel in aqueous solutions. The reagent reacts in aqueous medium at pH=7 to give a green- yellow complex with maximum absorbance at λmax=430nm. The stoichiometric composition of complex is CNi;HVMAB=(1:4). The molar absorptivity and complex constant formation were found to be ε=2.744×104 l. mol-1.cm-1 and βk =1.5382×105. We have studied all factors which affect the complex formation Ni-HPHMAB. Beer-Lambert was obeyed within the range (0.2-6) mg/l with a detection limit of 0.039 mg/l. The developed method was examined on Nickel standard solutions (RSD≤2.91%, recovery> 91 %). All results showed the accuracy, reliability and confirming the possibility of  using the reagent (HPHMAB) to determination of Nickel.
