Micellar extraction followed by flow injection ICP-AES for preconcentration and determination of aluminium ions.

ABSTRACT: In this study, a convenient and sensitive off-line cloud point extraction method (off-line CPE) was developed to preconcentrate trace amounts of aluminium (Al) ions prior to their determination by flow injection (FI) coupled to inductively coupled plasma-atomic emission spectrometry (ICP-AES). The method is based on the formation of a complex between Al³⁺ and 3, 2', 4', 5, 7-penta hydroxy flavone reagent, using Triton X-114 as a non-ionic surfactant to extract the formed complex and facilitate phase separation. Following extraction, the micellar phase containing Al ions was analyzed using ICP-AES coupled with a flow injection system (FI-ICP-AES). The off-line CPE variables were optimized using the Taguchi method, resulting in optimal conditions of pH 4.5, 1000 µg L^-1
