Extraction of cobalt and nickel salicylates: application to steel and industrial wastewater samples
Abstract
Aliquat 336 was used as an extractant for cobalt and nickel salicylates. The proposed method was applied to the determination of cobalt and nickel in alloys and industrial wastewater. The results obtained with the proposed method agree well with certified values and are comparable to those given by atomic absorption spectrometry. The method has a high degree of accuracy and precision.
