dc.description.abstractA method for the simultaneous spectrophotometric determination Cu(aq)2+, Ni(aq)2+, Co(aq)2+, and Fe(aq)2+, 3+ in refinery process streams based on multiwavelength analysis is proposed. The individual concentrations of the metallic ions present in quaternary mixtures was achieved by using molar absorptivities of each element at the wavelength of interest1 solving a simultaneous equation. A calibration model was setup simulating the refinery. The concentration of the elements predicted here were then used to predict the elements in an unknown sample. Simultaneous multicomponent determination of Cu2+, Ni2+, and Co2+ in process streams is possible. A good comparison of the laboratory analysis to the new method is proved.en_ZA
