Stoichiometry of Cu(II) Ion Extraction with di-2-ethylhexylphosphoric acid Dissolved in Waste Palm Cooking Oil

Alif Azwan Abdul Wahab, Siu Hua Chang, Ayub Md Som

 

Abstract:

This study was aimed to
determine the reaction stoichiometry between Cu(II) and di-2-ethylhexylphosphoric
acid (D2EHPA) in Waste Palm Cooking
Oil (WPCO). The stoichiometry was computed based on
the following
experimental
methods, namely slope analysis, loading test and Job’s
method. Slope analysis was used to measure the variation of the distribution coefficient

Keywords: Cu(II) extraction; D2EHPA; Reaction mechanism; Stoichiometry; Waste palm cooking oil
